  1. Hello, I just bought two retro Sega handheld consoles recently but I just realised that both of their screen are burnt as faulty. So I am look for an experienced repair for new LCD screens to replace them. I will happy to pay for LCD screens from websites like Ebay, Amazon, etc. I will pay you for your service to fix them. I will happy to drop them in Sydney metro but I don't mind to post them in only Australia as well. They are Sega Nomad Genesis and Sega Game Gear consoles. See pictures of them attached.
  2. Hello! I have a probably stupid dilemma, but no matter how I look high or low, all I can find online is how to connect a 2600 to a modern tv. Well, I don't want to connect it to a modern tv. I have a 2002 pk 4184 tv-radio I want to use. Ports on it? Simple question: it has exactly one; an "Ex Ant" (presumably external antenna) port. There's also an onboard antenna of course. Is there any sort of adapter that can connect the RF cable that came with the atari to it? Or am I just going to need to get an antenna box for the atari and find it's "station"? I feel like it would be better to hardwire it if I can. Here's an image of both items:
  3. Hello, I'm currently a newbie to Batari Basic and Visual bB for the Atari 2600 and had only begun to set up both programs. I installed both Batari Basic 1.5 and Visual bB build 568. So far according to the Windows 10 installation method I had extracted both zipped files and placed them together in a folder labeled "Atari2600". From there I launched the Visual bB configuration wizard and ran the install_win batch file. From there I am able to launch the Visual bB however I get error windows claiming to be script errors. I'm able to skip or ignore these messages and go into the program, from there everything appears to work as normal and I'm able to compile my code which at the moment has only been a playfield. When I test my code in the built in emulator, I'm then presented with an error regarding the file which will not allow me to run the code. Could I have possibly made an error while installing both programs or made an error with the configuration wizard? Any help or guidance would be greatly appreciated!
  4. Hey guys, so this time I messed up bad, no excuses here. Simply how can I fix this. Also will the product pictured below which is an conductive epoxy help? The game is Zelda for NES.
  5. I’ve had my odyssey for a while now and it’s worked perfectly since purchase, I’ve been using it on a ‘94 or so CRT and just recently bought a Curtis Mathis ‘81 to better fit the era (believe me i looked for a 70s... impossible) but now that it’s hooks to this older tv, it’s grainier (not the main issue) but now the wall won’t show! I’ve heard this being an issue before but it was never one for me so I never knew how to fix it. Also there are so many dials on this tv that I have no clue what they do I’ll attack some images if anyone could help me out
  6. Somehow my computer doesn't want to build DASM and I don't want to change my setup risking to break other projects. Can anyone create a DASM Windows executable from the latest source code for me?
  7. Seeking any information on: (Suche nach Informationen:) Wulf Becherer Eugen Baumgartner and software 3D-World. Towards the end of the retail support for the TI99/4a, I purchased - at full retail price- a copy of 3D-World. The documentation I have contains no maker or distributor name but the software contains the above two Germanic names with Copyright in 3D-World claimed by Becherer in the program code. I have found a little known commercial offering by AMERISOFT of 3D-World, and the manual I have and their manual are clearly from the same source, with the same weak translations and spelling errors, but theirs has added a copyright AMERISOFT note. Could this be a European program that has been "lifted" -officially or unofficially- by an American company? Amerisoft do not seem to have built a major presence in the TI World- but sadly neither do Becherer and Baumgartner. If anyone can help shed light on these gentlemen or on the circumstances of the program, I can add a note to the English manual I am recreating for the software. The Amerisoft disk is on wht. thanks S
  8. Hello, I’m wondering if anyone can identify the wood type the Magnavox odyssey uses on its woodgrain patter, I want to duplicate the pattern with another odyssey inspired project. Does anyone know the type or at least a good substitute? It’s a darker woodgrain
  9. Hy there. I got my very first Jaguar today. Hooked it up and it seem to work fine. Can't test much because I currently have no controller. Now comes the strange part. The start up screen has sound but is missing the growl when the Logo comes up. The music in the startup plays fine tough. Cybermorph starts up with sound effects but no music an no voice samples. What could be my problem? I am aware that the game could have mutet the sound by the previous owner but the partial missing sound seems fishy!
  10. I have been a pixel designer for about 10 years now and will guarantee to give your 2600 game the best graphics I possibly can. Any and all graphics in game I am willing to flesh out. Any serious offers can email me at [email protected] and we can talk further in depth. Thank you.
  11. Hi all, When I was a kid I used to go to the local arcade hall and play a platform game that played out in an asia / oriental world where a little guy shot balls in different colors at the enemy creatures. I wanna show it to my kids - but I cant recall the name of the game ? Help !!! =)
  12. I've been trying to mod my intellivion 2 to output composite video. I almost have the thing working, but the video signal is still having problems. text characters will start to shake after about 3 seconds of running, and there is a white line going down the screen lined up with the characters. I tried putting a 2000uf cap across the 5v line, but that didn't do anything. Ive checked the mod board multiple time times, but haven't found any problems with it that fixed the signal. also the rf modulator never output any video signal so i don't have any way to see if its a problem with the console. also don't have any extra rf modulators or consoles to test with.
  13. My intelvison 2 isn't outputting 12v when the rf modulator is connected. If I remove it the connection reads exactly 12v but as soon as its connected it drops to 11-6ish volts. Also was not getting any video from the rf out, and my composite mod is having problems keeping a stable signal. Wondering if the low voltage is the source of the problem. Also one of the ic's gets really hot and I'm not sure if that's related to the voltage or if that's normal. There is actually some yellowing inside the case in the area that its located.
  14. Hi guys its been a while since i posted on the forums however, My sound (monitor output sound, don't have rf box) is not working. I did a couple measurements with the multimeter on the POKEY and it seems that it does have voltage output at pin 37 (read that on forum where someone had the same audio problem with their 130xe) Personally, I have a hunch that it's not the POKEY chip itself rather it's a capacitor or resistor in the sound circuit since I'm pretty sure POKEY handles I/O and keyboard scanning (both of which work tested the disk drive with emulation with aspeQt/SIO2PC, however cassette playback does not work.) So I guess my question is should I just skip trying to get a donor POKEY and attempt to troubleshoot the sound circuit (potentially just shotgunning the entire circuit and replacing it all until it works)? I would gladly accept any advice from anyone! Thank you! I have the schematic of all the resistor/capacitor values here http://www.jsobola.atari8.info/derelit/xefsm.pdf
  15. I got an old odyssey 4000 from an attic a month or two ago, and I've been trying to get it working. I have the service manual and I made an attempt at an av mod based off of a thread I read here. The audio works, the system starts, and it seems like the game is running, but there is no video output to the tv. There is also not the voltage the service manual says I should have at the video out pin, or anywhere I can tell it connects to. Can anyone advise on what to check?
  16. Hi again, Did a bit of restructuring and now it seems to go to the correct bank on power up. The issue I think is right after that it jumps into no man's land a.k.a RAM and never returns which results in a black screen with a brown messed up playfield and a horrible death sound. 😝 The strange part is bank 0 is so small it is latterly only a few bytes in size with only a few calls to the required syncing subroutine, and then the title screen kernel which draws the title screen using the playfield and yes all the graphics are in the same bank.

  17. Hello all, long time reader, first time poster on the forums. I recently picked up a junk Coleco Telstar Combat system made in ‘77 for a couple dollars. It was pretty roached, but it’s a rather obscure system so I couldn’t pass it up. However, after getting it all cleaned up, I plugged it to my TV to test it out, but all I got was static and no signal. I tried many times turning the system off and on but mostly no signal would appear at all. Sometime a staticky signal would fade in and out, but it was very inconsistent. Once, I even got a vague image of the actually game screen to appear for a few seconds. I’m fairly confident that the video cable coming from the system itself is not the issue and I have it hooked up to a known working RF switch that works well with my Atari 2600. So, I opened the system back up, removed the RF shield, and began to adjust the RF inductors (I’m using a modern tv). ( I attached pics for reference) There appears to be 2 RF inductor adjustments under the shield, and a screw adjustment at the top right corner of the board. I started adjusting the orange (bottom) inductor but that only caused the video to go from no signal, to staticky image, back to no signal. So I tried to adjust the white (top) RF inductor, but it wouldn’t budge. Upon further inspection, I saw the slot inside this inductor had several cracks. I desoldered the inductor from the board to examine it further, but couldn’t get it to budge. After resoldering it back on, I still have the same issue, however, the static signal seems to become more and more scarce, leaving me with no signal as I fiddle more and more with the inductors. I also tried adjusting the screw adjuster to no avail, but I’m not really sure which RF adjusters I should/need to adjust. Would the cracking in the inductor be enough to inhibit the video signal completely? Is there anything else that could be causing this issue besides the inductors? I have a rather limited knowledge on electronics as I have only been attempting retro repairs for about a year and a half, so any new nuggets of knowledge are greatly appreciated! This is a really neat and rare system that I would like to have working in my collection. Feel free to ask questions if something isn’t clear. Thanks in advance! (Note: I have the same problem regardless if I’m using batteries or the power supply).
  18. Hi, Quick question, right now I have a 8k game using the standard F8 bankswitching scheme. Say I wanted to upgrade it to a 16k game via F6, how would I go about doing that? Do I just add the extra needed banks or is there a more precise procedure required?

  20. I'm not sure if anyone can help me with this, but ! Here goes ! I recently found a good emulator for the NEC PC6001. I need it to complete a video for my youtube channel but I'm having difficulties getting it to run a .cas image for pac-man that I found on Archives.org. I have't been able to find an alternate image of this game anywhere online. I do know it exists because of this. http://p6ers.net/hashi/emupacman.html I've tried to make it work in Mess & with PC6001VW Emulator to no avail. Anyone know where I can get an alternate rom image to work with this emulator. Because so far I'm turning up nothing in my searches. Attached are the clips I currently have.
  21. I am having a small issue with my code. I am trying to get the duck to stop when it reaches the top after hitting the flyaway state. However no matter what I try the code gets ignored. Source Code Relevant section Any of you experts have any ideas on what's going on?
  22. This forum has a lot of information hidden away in its depths. The repetition of the same questions indicates that locating that information is not as easy as it could be. Ideally I would like to create a metasearch so you could use one search box- but you would be deluged with possible answers and I don't have the resources anyway. So... I have created a page of searches for you to use. In some cases you need to prefix your search with "ti-99/4a" in quotes to focus the results on our favourite computer - I have noted this when especially relevant. How you use quotation marks is important in reducing unhelpful results - but overuse may cause you to miss something, so practice with varying search forms. Just putting lots of words without quotation marks is not usually useful and just one or two words may overwhelm you.. If I have omitted a resource rich web site (which does not require javascript!) do let me know.and I will update this offering. So- open this htm file in your browser and save it to your local machine where you can then open it at will. Have fun tisearch.htm
  23. Hey there everyone, I just started learning to program the Atari 2600 in Assembly recently and I think that I have learned a great deal. However, I seem to have hit a road block. Initially, when I first started programming playfields and backgrounds, I plugged the values in line by line like this: .fctbNone{ color:#e0e0e0; }.fctbStyle0{ color:#adff2f;font-style:oblique; }.fctbStyle3{ color:#ffd700; }.fctbStyle5{ color:#ee82ee; }.fctbStyle4{ color:#00bfff; }.fctbStyle2{ color:#ffa500; }.fctbStyle1{ color:#00ffff;font-weight:bold; }.fctbStyle1Style3{ color:#00ffff;font-weight:bold; }.fctbStyle2Style3{ color:#ffa500; }.fctbStyle6{ color:#ff6347; }.fctbStyle0Style6{ color:#adff2f;font-style:oblique; }; < GAME TITLE >; < AUTOR > processor 6502 include "vcs.h" include "macro.h" ;---------- LABELS ----------;---------------------------- SEG ORG $F000Reset; Initialize TIA/RAM; ------------------ LDX #0 LDA #0 Clear STA 0,X INX BNE Clear ; Initialize Labels; ----------------- COMPILE_VERSION = NTSC NTSC =#1 LDA #%00000001 STA $82 LDA #$BC STA COLUPF LDA $82 STA CTRLPF ; Start Game; ----------StartOfFrame LDA #0 STA VBLANK LDA #2 STA VSYNC ; VSYNC Signal STA WSYNC STA WSYNC STA WSYNC LDA #0 STA VSYNC ; Vertical Blank LDX #0 VerticalBlank STA WSYNC INX CPX #37 BNE VerticalBlank ; Scanlines LDX #0IDIOT INX LDA #$C4 STA COLUBK STA WSYNC CPX #40 BNE IDIOT LDA #$C4 STA COLUPF LDA #$0 STA COLUBK LDA #%11111111 STA PF0 STA PF1 LDA #%10111111 STA PF2 MORAL INX LDA #$CA STA COLUBK STA WSYNC CPX #42 BNE MORAL LDA #%11100000 STA PF0 LDA #%11001111 STA PF1 LDA #%00011111 STA PF2CORAL INX LDA #$CA STA COLUBK STA WSYNC CPX #44 BNE CORAL LDA #%11000000 STA PF0 LDA #%10000111 STA PF1 LDA #%00001111 STA PF2NORAL INX LDA #$CA STA COLUBK STA WSYNC CPX #46 BNE NORAL LDA #%10000000 STA PF0 LDA #%00000011 STA PF1 LDA #%00000111 STA PF2STEVE INX LDA #$CA STA COLUBK STA WSYNC CPX #48 BNE STEVE LDA #%00000000 STA PF0 LDA #%00000001 STA PF1 LDA #%00000011 STA PF2PTEVE INX LDA #$CA STA COLUBK STA WSYNC CPX #50 BNE PTEVE LDA #0 STA PF0 STA PF1 STA PF2BIGB INX LDA #$CA STA COLUBK STA WSYNC CPX #110 BNE BIGB BIGBB INX LDA #$2E STA COLUBK STA WSYNC CPX #130 BNE BIGBB BIGBBB INX LDA #$2C STA COLUBK STA WSYNC CPX #150 BNE BIGBBB FED INX LDA #$0 STA COLUBK STA WSYNC CPX #192 BNE FED EndScreen LDA #%01000010 STA VBLANK ; Overscan LDX #0Overscan STA WSYNC INX CPX #30 BNE Overscan ; Next Frame ; ---------- JMP StartOfFrame ORG $FFFA .word Reset .word Reset .word Reset END Thanks all! But while I was continuing in the tutorials, I found that my original methodology isnt really going to work (or will it? please let me know!) especially working with a great deal of sprites and backgrounds.

I did a mod to my JR around a year ago, and i ended up killing my board when i tried changing the jacks on it, and i can't find the original posting for the mod i Did. I saw this AV mod for the JR, and i was wondering how well it worked. https://atariage.com/howto/composite.html I think i remember some people saying the video quality wasn't the best, but I am just looking for something that is reasonably good enough to use. If the link does not work just try googling "atariage 2600 jr av"
  25. Hey guys. I've seen a lot of good help on this forum that I've used to help me diagnose my Atari 2600 4-switch that has not worked ever since I tried to install a widely used composite mod. (Kit Link Here) I installed it using an instructable (Instructable Link Here) I followed all instructions including removing q202, r209, r222, and c205, aaaaand... nothing it didn't work. (note: when I say nothing, I mean the TV says no signal.) I suspected bad connections but that wasn't it. I tried re-soldering the old components and that did something for a while but then it stopped. Next I thought that it wasn't getting enough power so I checked the power supply and 5v reg. Both were just fine except the 5v Reg had 2 of it's pins crossed. After uncrossing them I got some video for about two seconds and then it quit. (see attached video) I thought it was the chips now so I replaced all 3 (TIA, RIOT, and CPU) and this put me back to the same old no signal screen. I tried the old chips on a working system (w/o composite mod) and they gave a black screen. Not sure what to do at this point. Nothing is abnormally hot. Maybe my somewhat noob soldering skills maybe be a problem Cheers, kalgran Glitching.mp4
