Last night I ordered an Atari 2600 Custom Cartridge from Atari Age. This was after reading the description for it, because It appears that you can order a reproduction of a rare game with the original artwork, with added text saying "Reproduction Cartridge." This is fine for me because I only want to be able to play games on actual Atari hardware that I would never be able to afford otherwise. And I don't much like Everdrives. Before getting to the PAL question, the rare game that I wish to have a reproduction of is Demolition Herby. It's like Amidar and Spiderdroid, except it's faster, adds a touch of vehicular combat, and is loads of fun to play. So far I've only been able to play it thru emulation, but I want to be able to play it on actual Atari hardware. After I ordered and paid for an Atari 2600 Custom Cartridge, I added the following note to the order: I need a reproduction of "Demolition Herbie" for my own use. https://atariage.com/software_page.php?SoftwareLabelID=132 (I meant Herby) Now on to the PAL question. Can PAL games be placed onto an NTSC cartridge? There are PAL exclusives that I want to be able to play on my Atari hardware, which use the NTSC standard. Those games include Acid Drop and Meteor Defense for example. Can anyone answer the PAL question for me? Both of the mentioned PAL exclusives run on my emulator, EMU7800, but Acid Drop cuts of the bottom 30% or so off the screen, and Meteor Defense runs, but in black and white only. Most PAL games run fine though. Thanks in advance. -Mark -
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.)

If any of you missed SvOlli's post, there is a 512 byte demo competition at the Nordlicht DemoParty this year. I have been working on an entry for the past couple weeks, and it is very close to being finished. The original plan was to have colorful dots slowly raining down the screen with some peaceful sounding music, but I needed something a little more interesting, so I added text as well. As of now, there is no music, but I have 45 bytes of ROM left to work with, plus plenty of unused bits from another table. I will do my best to add a 2-voice soundtrack, and if I have a few bytes leftover, I will try to fix the "R" character. (That might give you a hint to how I am doing the character graphics). I am posting the current .bin here, but I won't be posting any source code until after the contest is over. Any feedback is appreciated! If you have a PAL system and a Harmony cart, please test it out for me, since I don't have a PAL setup. I specifically am curious about whether or not the top of the kernel is aligned properly. demo2018.bin

I noticed that it doesn't fit in the slot, so is there some kind of adapter to make it work on my NTSC Atari 2600? I'm aware of the vídeo output issue PAL games have on NTSC TVs, but I already have a solution for that.

Hey guys, I decided to try this forum as it might garner some more attention than in the Marketplace section. I'm near to completion with my PAL release Atari 7800 collection and there are three games that I've been having real difficulty in getting... - Kung Fu Master - F-18 Hornet - Tomcat: F-14 Simulator All three of these games were released in PAL territories under the HES/Salu branding and I'm looking for boxed versions of these games! I'm also on the hunt for a boxed PAL copy of Dark Chambers. Is anyone willing to sell any of these? I don't care too much about the condition! Thanks! -
I recently acquired a CGL M5. Its a machine I've wanted since they first came out. I loved the design of the Sord M5, and even though the CGL version doesn't share the Sord's elegant "M5" logo, it wasn't very expensive and allowed me to explore the great "M5 Multi II" multi-game ROM made and sold by Charlie Robson. Now this post may be in the wrong forum. But you guys know TI hardware better than anyone, and the CGL M5 uses the TMS9929A VDP also found in European spec TI99/4As among many other machines. The M5 then converts the R-Y, Y, B-Y output to composite PAL. But my monitor is a North American Commodore 1084, and expects composite NTSC or RGB. I've looked around for a 9929A to RGB conversion schematic, and there are a few, including the one linked in this document from a Sega SC3000 forum: http://www.smspower.org/forums/2325-RYBYYOutputFromSC3000VDPTMS9929 But I also see that some people have tried this approach and met with mixed results, including one ColecoVision owner who it seemed may have fried his machine in the effort (see post 26) http://atariage.com/forums/topic/110598-colecovision-av-out/page-2 This guy has a neat looking board that it seems would make pulling RGB from the TMS9929A straight forward, and has generously shared all the schematics and build files, but since I have never had a board made before I am way out of my depth on this one: https://hackaday.io/project/13056-tms9929a-rgb-and-component-adapter So another approach might be to convert the CGL M5 to use a TMS9918A instead? Can that be done? From an evening spent looking at websites, it seems I might be able to remove the 9929A and insert the 9918A. Leave pins 35 and 38 NC, and then drive pin 36 directly to the RCA jack. I'd need to replace the oscillator too to get the right color signal for NTSC, and probably burn a Sord NTSC BIOS so that the unit reports itself as NTSC to those games that depend on timing. So how insane is the replacement plan? Would it work in theory? Assuming there isn't something else in the Sord's design that prevents it? Can you tap composite NTSC right off pin 36 of the VDP? What else would I need? Diodes? Resistors? And if these questions are worthy of a face palm, should I just go hunt for a native NTSC Sord model? I can also lug my Sony PVM out of the closet which has PAL and NTSC Composite and S-Video, but doesn't have RGB, so the Amiga and ST displays look awful. Thanks for any pointers.

In Session 7 of "Atari 2600 Programing for Newbies" I learned that 50Hz PAL has up to 242 lines of actual picture. However, the Stella Programmer's Guide says to use 228 picture lines when doing a conversion from NTSC to PAL (see screenshot below). Which one would make most sense to use? I guess when converting an NTSC game to PAL50, it would be even easier to use 192 visible scanlines (just like NTSC) and increase the number of lines in VBLANK and OVERSCAN accordingly. Or would that cause issues? (other than not using the full screen estate). Are there any best practices to follow when creating a game that should run on NTSC, PAL60 and PAL50?

We hear a lot about the Atari and its NTSC artifact being used by programmers to get more colours in hi-res modes but I don't think I've ever seen (and couldn't find when I searched) any discussion of PAL games that took advantage of the way PAL displays horizontally blur the display allowing for dithering effects to increase the palette and achieve transparency effects or half bright colours the way it was done on machines like the mega drive and spectrum. Are there any PAL games on the Atari that use these techniques?

I was pointed in the direction of this forum by some good folks over on Reddit. I have come into the possession of what seems to be a PAL release of Star Strike by Telegames. I have not been able to get much information about it, other than a few mentions, and its appearance in a few databases. http://www.atarimania.com/game-atari-2600-vcs-star-strike_7809.html and http://www.completeroms.com/dl/atari-2600/star-strike-telegames-pal-/1760 I've been provided with a little more information about Telegames and how they came to license the game, but putting a value on it has proven very difficult. There are no eBay listings that I have been able to find, let alone a finished auction. I am aware this game -even though, perhaps rare - might not necessarily be that valuable. I'm not an Atari collector, my preference lies with the PC and PS1/2 consoles for now, so this game would probably be part of a trade in the future. https://imgur.com/a/1XhNZel Thanks for your time.

Good afternoon gents. Yesterday I tried Defender on my Colecovision console for the first time (well okay, that's being late!) and saw that the radar is blank. I've read this old thread here and it seems this is a common and somehow expected problem: http://www.atariage....ap-doesnt-work/ Now the question is: has anyone found or selected a ROM image that doesn't show this problem? Is anyone able to and willing to fix any of the ROM images available so that ther radar will show up correctly? By the way, I was very impressed by such a HUGE issue and I wonder how it could go under silence back then in the eighties. OK for the first production batch, these things may happen, but how could it be they didn't fix it in the next batches?

Since I have begun dabbling in programming for the Atari 2600, I have become interested in running a PAL system for testing purposes. I have one wood-grain 4-switch NTSC VCS, and there are multiple PAL VCS's for sale on eBay at reasonable prices. My main question is about displaying the signal. I obviously don't have a PAL CRT, and the only way to get one would be to pay a fortune to ship one from across the pond. Not to mention that I would need to power it with the proper voltage at 50Hz. I have heard that the Commodore 64 1080/1084 monitors will accept PAL signals, though (I think), but getting a PAL CRT is pretty much out of the question for now. I was thinking of instead getting a signal converter so I could display the picture on a NTSC CRT, something like in this video. It seems too good to be true, but could something as inexpensive as this converter be all I need? One other question. I noticed that my power supply converts from 110V 60Hz to 9v DC. If I plug a PAL system into a US wall outlet, will it work properly? Or will I need a different power supply? I would assume that both NTSC and PAL systems run at 9V, but I may be wrong.

Hello everyone, First of all: I am new to this forum and to the Atari 2600. I'm not sure if this is the right way/place to ask this, so if not, please tell me. I recently bought an Atari 2600 (darth vader) PAL console in untested condition. I got it to work mostly, the problems it had have mostly been solved except for one: There is interference in the video (RF) signal, which results in white dots moving around the screen in waves. (I have attached a video and an image of it) Here is what I already tried: -Use an NES (nintendo) RF switch instead of the built-in cable: introduced more static and the white dots remained. -Disconnected the RF cable from the Atari's motherboard and tried it with an NES: worked perfectly fine, no static at all. -Cleaned both connectors and the cable with some alcohol: Improved nothing. -Finetuned the tv channel multiple times. Important to mention is that the cable has been damaged and soldered back together by the previous owner, but since it worked fine with the NES i don't think this is the problem. My guess would be that there is something wrong with the big capacitor on the board or the RF modulator. It could also be due to the power adapter, it is one of those universal adapters on which you can set the voltage, I set it to 9V, I dont have an original one. Any help or tips would be greatly apriciated. MOV_0053.mp4

Stella has an option which emulates color loss on PAL CRT TVs. This color loss, where only grays instead of colors are displayed, happens in Stella when the scanline count is an odd number and a PAL mode is selected. This has always been assumed to be correct. But there exist a number of ROMs, which produce an odd number of scanlines and are clearly meant to be PAL. This finally made me wonder. And therefore I wrote a simple test program and tested it on my own PAL CRT (14" Sony Trinitron KV-14LT1E), attached to my composite modded console. And no matter what number of scanlines I try, there is no color loss at all! Now I wonder if this is special for my TV/console combination (most likely) or if color loss doesn't work like we assumed for 20 years now. If you own a PAL CRT, please give the attached program a try. Use joystick up and down to change the number of scanlines. Do you get a colored picture for odd scanlines too? When you report back, please provide some details about the TV and the input (antenna, composite, RGB...) you have used too. Thanks in advance! ColorLoss.bin
