  3. ***UPDATE: Download the ENTIRE NTSC & PAL Atari 7800 set HERE. Original Post follows... This is relatively important, especially for our game developers I'm hoping this helps and makes color conversion from one format to another a bit easier. Download both raw color palettes here: There is no bias and both palettes share the following same attributes per standard Atari 7800 configuration without any display device influence (And no 'warm-up' factor). This is system cold/factory default settings as follows: Contrast = 0.05 Brightness = 0.00 Color = 0.22 Phase = 25.7 Colorburst = 180 degrees This NTSC palette and the ones to follow are brand new and never released before due to error on my part, but this PAL palette has been released before under a different name, again due to errors on my part. Again, they are both the 'raw' ones for their respective regions. Your input (especially PAL users as I am in NTSC land) is greatly appreciated for this thread. Thank You, Robert
  4. Listed for sale here are 86 Atari 2600 cartridge and manual sets separated by company, of which there are 13 represented. Unless otherwise noted*, all carts are: - in complete company sets - mint condition - NTSC - included with original manuals and inserts (no catalogs) Hi-res scans or photos will be provided if requested. Asking prices are based on the midpoint between what I paid back in the day and current VGPC.com sales listings, where available. I encourage all interested parties to do their own research, but I think you'll find these prices to be bargains. Prices DO NOT include shipping, but Priority Mail shipping will be free to US buyers who purchase 2 or more sets. International buyers please PM do discuss shipping options. Please PM questions, comments, offers to buy... American Videogame - 1 game - $19---> SOLD Bit Corp Re-release (*All PAL) - 7 games - $75 *Set incomplete - does not include Dancing Plates, Space Tunnel. *Quelle Phantompanzer cart was in Bit Phantom Tank box when I bought it in 2001; manual is a copy. Bomb (*All PAL) - 2 games - $130---> SOLD *Price is MY COST from 2001. No auction data available. *Set incomplete - does not include Assault, Great Escape. *Z-Tack label is faded. *Included manuals are in German and French only. Data Age - 8 games - $78----> SOLD First Star - 1 game - $87 > SOLD *Cart is standard, NOT Xonox style. FOX - 17 games - $200----> SOLD *7 of the 17 carts have altered labels. Back in the mid-'80's, when nobody cared, I resented Fox for not putting the title of every game on the end label. After all, who doesn't store their carts end-label out?! So I sliced them and swapped the titles on the fronts with the copyright info on the ends of the following titles: *Bank Heist *Crypts of Chaos *Earth Dies Screaming *Flash Gordon *M*A*S*H *Revenge of the Beefsteak Tomatoes *SpaceMaster X-7 I suppose a buyer, if any, could swap them back, but they can never again be considered mint. Nevertheless, the asking price is $169 less than current VGPC pricing. Is that not worth some less-than-pristine labels? Froggo - 6 games - $74----> SOLD Konami - 3 games - $52----> SOLD M Network - 17 games - $150----> SOLD Salu Exclusives (*All PAL) - 3 games (plus 1) - $70 *My Golf is a HES exclusive but is included here simply because this is the version I acquired.

Sears Exclusives - 3 games - $44----- > SOLD U S Games - 14 games - $123----> SOLD *The following 4 carts are beveled-style: Entombed, Picnic, Piece 'O Cake, Raft Rider.
  5. Hello! I'm wondering of anyone has investigated the feasibility of modding a 2600 so that you can switch between clock frequencies and/or color palettes. The goal of such a project would be to play cartridges of differing regions on the same machine. I've seen a similar project on a Commodore 16 where the clock crystal was replaced with an Arduino, the latter programmed to output different selectable frequencies to produce a signal for PAL and NTSC video. As for the color palette, I believe that would require a swap of the TIA chip, which could be done manually if the board is socketed. I haven't studied the schematic, and a cursory search doesn't show anything useful. To anyone with the hardware experience, do these ideas seem sound? My assumption is that the only difference between a PAL, NTSC, and SECAM 2600 are the clock crystal and TIA since the game cartridge does all the video synch. Steve Guidi
  6. Hi folks, I am new at AtariAge. Months ago, I've got an AV-modded european Atari 2600 Jr. (Rev. F board) in a great condition for cheap. However, here at my country (Brazil), PAL-B compatible TV sets are rare to find. The closest color system that is supported by most TVs is PAL-N (PAL variation used in Argentina and a few more countries in South America). I tried to replace the 4.433618 MHz XTAL with a 3.582056 MHz one, but that gave me no colors in any PAL-N compatible set. Also tried to replace the 3.546894 MHz one with a second 3.582056 MHz XTAL, but still gave me nothing but B&W picture. Is there something I can do to make this console output PAL-N? Both systems are 50 Hz and have the same resolution, so it should work somehow. Thanks a lot!
  7. New palettes for Stella - Stella257 & Stella267. Both palettes contain updated NTSC and PAL colors, SECAM retains the standard Stella settings. Stella257 has the 180 degree colorburst in place resulting in 1$ and F$ being a near exact match (Visually they will appear exact to most). Stella267 closer represents the standard Stella palette having a slight phase shift from the 180 degree colorburst, providing the most noticeable change to F$ - darker browns in comparison to 1$, and E$ - giving a more neutral balance between a green and brown hue, instead of a stronger green presence under Stella257. There is no manipulation of contrast, brightness, or gamma for these palettes. Stella has internal controls to handle that Download the palettes here: Stella2XX_Palettes_20130911.zip Screen captures to follow (click pics to enlarge and remove distortion) are in this order: Stella (Standard) --> Stella257 --> Stella267 Color Bar Generation (1984) (VideoSoft) (NTSC) 'Title Screen' & 'Color Bars' [Composite mode @ Stella default values] Color Test (26-09-2002) (Eckhard Stolberg) (NTSC) [Composite mode @ Stella default values] [TV mode disabled (AKA RGB)] Color Test (26-09-2002) (Eckhard Stolberg) (PAL) [Composite mode @ Stella default values] [TV mode disabled (AKA RGB)] Enjoy.
  8. Short and Sweet version... The most complete and diverse palettes available; including not only "tint/hue" but internal console "pot adjustments" as well which in part accounts for variances between systems and displays. A range of brilliance and saturation levels are included too. Grab the complete set with below description and explanation here: GCCFINALXX_20130624.zip *UPDATED 6/24* - Additional color logic/decode for neutral "pot" palettes and improved naming convention. Detailed version... The GCCFINALXX palettes offer a robust range of settings with much diversity regarding color control. It includes "tint" adjustment (as typical found on a display's end-user controls) as well as "pot" adjustment (Color tuning found inside the 7800 console). Additionally, there is a range of color brilliance and saturation settings from the raw/base levels to extreme levels. Here is a typical file name: "NTSC_GCCFINAL1G_XTRBRT_LOWSAT.pal" It describes the palette in the following four areas: I. Region II. Palette Family Pot and Tint/Hue Setting III. Brilliance Setting IV. Saturation Level I. REGION: The region difference is noted by either NTSC or PAL in the file name. II. PALETTE FAMILY POT / TINT SETTING The difference respecting the "pot adjustment" is noted by either number 1, 2, or 3 in the file name: 1 = More Blue to Red, Less Blue to Green. 2 = Neutral 3 = More Blue to Green, Less Blue to Red. The difference respecting the "tint/hue setting" is noted by either a letter G, N, or R. G = More Green N = Neutral R = More Red Complete Color Base line: GCCFINAL1G = TINT is more green / POT is more blue over red, less blue over green GCCFINAL2G = TINT is more green / POT is neutral GCCFINAL2G-ALT = TINT is more green / POT is neutral (Alternate color logic) GCCFINAL3G = TINT is more green / POT is more blue over green, less blue over red GCCFINAL1N = TINT is neutral / POT is more blue over red, less blue over green GCCFINAL2N = TINT is neutral / POT is neutral GCCFINAL2N-ALT = TINT is neutral / POT is neutral (Alternate color logic) GCCFINAL3N = TINT is neutral / POT is more blue over green, less blue over red GCCFINAL1R = TINT is more red / POT is more blue over red, less blue over green GCCFINAL2R = TINT is more red / POT is neutral GCCFINAL2R-ALT = TINT is more red / POT is neutral (Alternate color logic) GCCFINAL3R = TINT is more red / POT is more blue over green, less blue over red III. BRILLIANCE: The level of color brilliance or brightness is noted using the following: LOW = Base/Raw Level MED = Average Level XTR = Extreme Level Complete Brilliance Line (Least to Greatest) = LOWBRT, MEDBRT, XTRBRT IV. SATURATION: The level of color saturation is noted using the following: LOW = Base/Raw Level MED = Average Level XTR = Extreme Level Complete Saturation Line (Least to Greatest) = LOWSAT, MEDSAT, XTRSAT A few final thoughts...Keep in mind that your current display device (Computer monitor can have a slant/push) may result in you choosing a palette that could seem like an unlikely candidate or choice. For example, have you ever read a review where they says the monitor has, not a red, but a "pink push", or "too much pink"? The actual issue may be there is a stronger than expected or accustomed to blue over red ratio. In that scenario, you may want to counter it with one of the GCCFINAL3X palettes depending on how strong the monitor's slant/push is of "pink". Or if you have a display with a red push, you may want or/and need to counter it with one of the GCCFINALXG palettes. Then again, your current display may be perfectly color calibrated and it is the original 7800 system or device you play(ed) it on that leans or slants in a certain direction regarding colors as a result of the pot adjustment or television configuration. It's all factors to keep in mind when trying the select a palette that looks 'right' to you. Please note too, one palette may look just right for one game and very wrong for another. A few titles there is little noticeable changes (I.E. Dig Dug) among a slew of different palettes. In other titles, each palette will make a obvious and distinct difference (I.E. Xenophobe). ENJOY!
  9. Hi. I recently bought an Atari Jaguar of eBay. It is PAL. It seems to power on and shows a green light. But when I hook it up to the TV, I see a distorted image (what you see when you don’t insert an Atari 2600 cartridge properly) I’ve been told by someone that the console is working as it should and the image I see is caused by the PAL system being used in an NTSC country. What do you think? By the way, I am using the AV signal. Is there something I need to buy to get it working? Thank you!
  10. I've recently been offered 3 2600 games; 'Dancing Plate', 'Sea Monster' & 'Space Tunnel' all of which I know very little about, and was hoping someone could give me some insight, as when searching i've found very little information. All games are in their boxes with manuals and appear to be in excellent condition. Image is attached. Would really appreciate anyone who could help shed some light on the rarity and value of these games. Thanks!
  11. Hi y'all, and Happy New Year! I recently picked up a heavy 6-switcher on eBay, which had an AV mod fitted (by "Atarimania9", a UK seller from London). I am finding that all the carts which came with the console, are fine - but any new ones I buy (and I've purchased carts from about 8 different UK sellers) are ALL playing in black and white only?? So, could the problem be that I have an NTSC console (and supplied carts), but playing UK (PAL) carts is the issue? Cheers all, and best wishes,. Matt.
  12. Hello, I bought an Atari 2600 from a flea market today and since It didn't come with a power cord I have no idea whether It is PAL or NTSC. My question is, how can I know what kind of Atari 2600 I have without risking to break the thing down because of overcharge. Instead of a charger, It came with a cord that looks like It has a US socket. Please leave a response If you know something.
  13. Hi everybody! I have bought an ATARI 2600 woody heavy sixter and im facing a problem.. In my crt (sony trinitron 14") tv i have great pic but no sound..

  14.

  15. Hi there. I'm working on a game which I intend to work on the base model Atari 8-bit computers, i.e. those with 8k memory. (I got the constrained programming bug working on some entries for the yearly minigame compo.) Can anyone confirm whether there was such a thing as an 8k PAL Atari 400 or 800? I've inferred from what I've read that there must have been 8k NTSC versions of both computer, since NTSC versions were released first. Unfortunately, I can't make seem to find a definitive answer about PAL versions. The computers were sold released slightly later in Europe (1981?). Thanks for any information or links, Malcolm
  16. Hello, I recently bought an Atari 2600 and It did not come with a power cord. I managed to find one, but there is a voltage switch on it, so I have to set the right voltage. If you know how many volts I need in order to play a PAL Atari 2600 in Europe and not make It blow up, leave an answer. By the way, the power cord is capable of giving me power from 3 volts up to 12 volts.
  17. Hi, I'v been a collector for many years, but never been active on forums such as AA. Lately I've noticed the topic PAL Heavy 6-er pop up here and there. Since I (well a collector friend has it now) found a PAL Heavy myself, I thought it would be nice to post pictures. It's a fleamarket find in the Netherlands. Found with some original text label carts. Bought from a non - collector, non reseller, private seller. Cheers, Rene
  18. Hi Guys This is my first post here so please be gentle with me. I'm from the UK and I've recently bought a couple of Heavy Sixer's from the States. I have modded one of them with a composite video kit and it works great. However, I was wondering what else I would need to do to convert the system into a PAL unit? I've read about the TIA and how it differs so my questions are: a) Could I replace the system board only with a PAL light sixer, keeping the switch board and all other original components? Would this work? b) If I was to keep the system board and replace the TIA with a PAL unit, is there anything else I need to consider? The info on the internet I've found seems to be pretty vague. I read something about the crystal also needing replacing and maybe some other bits? Thanks in advance
  19. I have started doing some modding on my Game Gear about 2 months ago and its been pretty fun and exciting (successful LED backlight mod and battery replacement for the Powerback so far. WOOT!). I started looking into a 50hz/60hz mod for the GG VA1 board to play my PAL master system games on by following various posts switching the NTSC pin from the Sega 315-5535 to a 5V source. After going through the Service Manuals (http://gamesx.com/wiki/lib/exe/fetch.php?media=schematics:service_manual_-_game_gear_va1.pdf) and other posts, I am having a very silly issue: Where is Pin 118 on the Sega 315-5535 IC? I see some possible spots on the other side of the chip, but I don't want to start chopping leads before knowing exactly which pin I'm sending a 5V signal to. I'm modifying a USA VA1 837-9024 Game Gear board. Any and all help would be greatly appreciated. I've tried some other communities to find this information and I've found the AtariAge community to be very helpful in the past. Take care guys !
  20. Hi people, when I bought my Jaguar back in 1995(?) here in Austria, it came with Cybermorph packed-in. Just to expand my collection of boxed Jaguar games, I recently bought a boxed Cybermorph. The cart has the number J9000E on it, so it is the European PAL version. The manual has three languages (English, French, German), so this is PAL too. But the box is only in English and has the number J9000 on it, meaning it would be an NTSC box. So my question is: Does a multilingual box for Cybermorph exist? Possible that someone just put my PAL Cybermorph cart + manual in an NTSC box. Or was it sold that way in Europe? I know that a boxed Cybermorph is kind of rare because most(?) Jaguars had Cybermorph as pack-in. But maybe someone has a multilingual Cybermorph box or has at least seen one?
  21. Since her sister Maria received new clothes and Stella received new clothes, it was only a matter of time. Download the Atari 5200 palette files here: Pam2XX_Palettes_20131108.zip The 'Pam' palette files are presented with the same options as the 'Maria' palette files. There is a "base" palette plus the following options: x0 = Saturation Increase x1 x2 = Gamma Increase and Saturation Deltas x3 x4 x5 = Gamma and Saturation Increase with Contrast Deltas x6 x7 x8 = Saturation Increase with Contrast Deltas x9 Also like the Maria and Stella palettes, we have Phase Shifts 24.7 through 27.7 degrees in 0.5 degree increments. In addition to palette files with the '*.pal' file extension, the complete set above is also presented with the '*.act' file extension (Used with Atari 5200 emulators such as Atari800Win Plus, Jum52, & kat5200). Phase Shifting examples follow utilizing the x0 [saturation increase only] NTSC palette in the following order... Pam247NTSCx0 --> Pam252NTSCx0 --> Pam257NTSCx0 --> Pam262NTSCx0 --> Pam267NTSCx0 --> Pam272NTSCx0 --> Pam277NTSCx0. Pole Position: Joust: The next few are highlighting the two ends of the phase shift spectrum and a logical 'middle' ground (See explanation below): Pam247NTSCx0 --> Pam262NTSCx0 --> Pam277NTSCx0 Astro Chase: Moon Patrol: Mr. Do's Castle: Ms. Pac-Man: Pitfall II: Here are examples showcasing the different options within each phase shift. Phase Shift 26.2 degrees is selected in this order: PAM262NTSC --> PAM262NTSCx0 --> PAM262NTSCx1 --> PAM262NTSCx2 --> PAM262NTSCx3 --> PAM262NTSCx4 --> PAM262NTSCx5 --> PAM262NTSCx6 --> PAM262NTSCx7 --> PAM262NTSCx8 --> PAM262NTSCx9 Frogger: Pitfall: Color Bars with Reference from PAM Diagnostic [sALT] Cart v1.1: Pam247NTSC --> Pam252NTSC --> Pam257NTSC --> Pam262NTSC --> Pam267NTSC --> Pam272NTSC --> Pam277NTSC. GTIA CHIP - NTSC C014805 Official Document Color Order: Atari 5200 Field Service Manual: Per the technical documents referenced above the following can be deduced: Directions were given for the color just below and above the (grey) reference bar to be within one shade of each other. Under the same reference document, directions are given for it to be the same color. Phase Shift 25.7 degrees - matching Hue 1x, 15x and the color below the reference grey bar fits making it the same color. Accounting for system 'warm-up'/phase shifting as well as the instructions for it to be within one shade of each other would make Phase Shift 26.2 a realistic logical choice. It also collaborates with the official document color order: Hue 1x = Gold, Hue 2x = Orange, Hue 15x/F$ = Light-Orange; Phase Shift 26.2 places Hue 15x/F$ between Hue 1x, gold and Hue 2x, orange; a light orange in color. Here is an alternative capture of the color bars from the PAM Diagnostic [sALT] Cart v1.1 with Phase Shift 26.2 degrees in place by utilizing the 'Pam262NTSC' palette within kat5200's NTSC video simulation mode along with a few game captures: (Click on the capture to remove some of the distortion) Hue 1x for NTSC is intended to be gold, not green-yellow/yellow-green. Gold is how Hue 1x appears under a CRT - the original and intended display device for the system. A green-yellow/yellow-green Hue 1x is how the NTSC 5200 palette is manipulated and modified (in part) under a modern flat panel (I.E. LCD/LED/Plasma) display. The above harmonizes with what has been documented for the Atari 2600 and Atari 7800 systems as well, regarding their NTSC color palette. Although there is no Atari 5200 PAL system the palettes offered in the download for the PAL region are theoretical ones based upon how the colors align under the Atari 7800 PAL system (Since Atari 5200 NTSC and Atari 7800 NTSC share essentially the same palette when viewed on a CRT). However, it should be noted that PAL 8-bit (400/800) Atari computer systems appear to provide the same - or an *extremely* similar - palette of NTSC Atari 5200 consoles displayed on a CRT. Additionally, that would also mean that Atari 8-bit NTSC and PAL palettes are the same (Or extremely similar) from at least the 'base' level. Once actually processed through display circuitry from their respective region as well as slight hardware system differences (There is an additional oscillator for 8-bit PAL systems driving color frequencies), other items such as NTSC color 'artifacting' would not be present under PAL. A thorough summary of Atari 2600/5200/7800 console system palettes is here.
  22. Download the palettes here [updated 8/30]: 2X7-PROSYSTEM_20130830.zip The '2X7-PROSYSTEM' palettes (25.7 degrees --> 26.7 degress --> 27.7 degrees)... NTSC: PAL: Why? Technically the phase shift of the 7800 is ~25.7; actually, 25.714 according to the math here... https://sites.google.com/site/atari7800wiki/rgb (Thank you Eric Ball). The reality though is most (all?) 7800 systems fluctuate the phase shift higher as the system 'warms up'; additionally there is a variable resistor which also impacts the ultimate end results. The color references affected the most - and consequently most noticeable - are values E$ and F$. At the 25.7 setting colors 1$ and F$ match near exact. To the naked eye they in fact look exact. According to the books this would be proper having a 180 degree color-burst resulting. However, even a new system I obtained within the last year does not stay at that degree. There is a deviation from it, resulting in the shift going higher than 25.7 degrees. The question is how much greater do we go? Simply stated, color F$ more realistically ends up between the hue of Color 1$ and 2$; darker than 1$, but lighter than 2$. If we set the phase two degrees higher (27.7) we end up with colors E$ and F$ as a near exact match of colors 1$ and 2$. Some systems, including one of my own, phases this much and even higher (~28.7) over several hours (To the point where E$ and F$ fall in between 2$ and 3$ in hue - and most other values almost look like they have shifted a complete row (I.E. 8$ starts to look like a 9$, 9$ starts to look like a A$, etc.); but now that is swinging the pendulum too far in the other direction. So, if 25.7 is technically accurate, but hardly remains the reality, and 27.7 brings too much of a phase shift to the palette, then a happy medium would be 26.7. Setting the phase to 26.7 we obtain a color F$ that is in between the hues of color 1$ and 2$. MESS, in fact, has F$ documented (Thank you Dan Boris) as a 'light orange' range, whereas 1$ is a 'gold' range and 2$ is a 'orange' range. Additionally, we obtain light browns from 1$, while now having darker browns set under F$. Looking at color E$ under the 26.7 setting, it falls right as a 'pea soup', the 'Linda Blair special', puke-ish green throughout; placing it in between a green and a brown color. Going back to 25.7 causes E$ to become a stronger green on the lower end, swinging the pendulum to 27.7 makes E$ a brown color. The often noted intension is for the E$ range to fall between a green and a brown; it is arguably better achieved at 26.7. The extensive work done in brightness, contrast, saturation with the literally hundreds of palettes created and viewed across half dozen displays, along with the input of the community, has helped achieved a nicely saturated and bright palette setting from the base values as shown above. That is easily adjusted and open to interpretation of course, so if you want something more/less saturated, brighter, etc...Just ask. Additionally, the "BASE" palettes are being included for those who perhaps just want the base values and/or like to self-adjust saturation, brightness, contrast, etc. BASE '2X7-PROSYSTEM' palettes (25.7 degrees --> 26.7 degrees --> 27.7 degrees)... NTSC: PAL: Unlike the GCCFINAL palettes, we are not looking to factor in a wide range of television tints or pot adjustments. These palettes presumes a properly calibrated/pot adjusted 7800 and a television which falls within a neutral tint setting - and expects similar from the monitor it is being displayed upon. It's almost a certainty that programming color choices were made on systems with a variety of phase settings as well. For instance, some games like Choplifter! and Midnight Mutants look better with a higher (27.7) phase shift, but others like Pole Position II and Joust look better with a lower (25.7) one. Here is a look at Choplifter! - (25.7 --> 26.7 --> 27.7): Notice how much better the sky and ground appear with a system that phase shifts higher. Here is a look at Joust - (25.7 --> 26.7 --> 27.7): Notice how bad the enemy bird wings look with a higher phase shift. They lose their green. Just to emphasize, the above are not utilizing any tint/hue control or manipulation. There is no manual changing of RGB values or proportions. This is not the same as a television display tint/hue control. This comes strictly from the console itself and is not a pot adjustment either. *Note to 7800 game developers: Avoid color E$ like the plague!* Interestingly enough, a 'perfect Fuji' (Enable the BIOS) demands '257-PROSYSTEM' - and it is the technically accurate ideal, if not actually experienced for a long duration of time. Here is the Fuji captured under NTSC (25.7 degrees --> 26.7 degrees --> 27.7 degrees): *The differences are likely less noticeable on a CRT especially when animated, but still worth noting* If you have a system that truly sticks to a 25.7 degree shift, it's covered here, as well as those going beyond, 26.7 degrees, up to 27.7 degrees. UPDATE 8/28: Received request for less saturated palettes. Lighter/less saturated palettes have been added. Here are the '2X7-PROSYSTEM-LT' palettes (25.7 degrees --> 26.7 degrees --> 27.7 degrees)... NTSC: PAL:
  23. I'm still gathering all the bits to get classic gaming systems up in working order, and decided I'll probably go for an OSSC or Retrotink2 on my HDTV as opposed to using the Trinitron in my basement. I recall reading that HDMI 1080P sets can handle 50hz inputs - is this true? What would be the logistics of getting both NTSC and PAL games working? I'm really only interested in PAL for a handful of Mega Drive games that originated as Amiga ports (Chaos Engine, etc.)
  24. Open to reasonable offers on 3 complete in box Atari 2600 games. All are in fantastic condition. Happy to provide more pictures upon request. Located in Australia. Thanks!
  25. Hi, I'm looking for help pricing these two games. I did not found any of these on ebay. Thank you.
