  1. I have an issue with two games on my //e, Maniac Mansion and Prince of Persia. They flat out don't work, no matter that disk images I try. I've ruled out bad disks by copying known good games to those same disks and they work fine. I've heard that Maniac and POP require 128K RAM to run, I don't know if I have that. I have a //e with a 65c02 marker on the keyboard, I don't know what exact model of //e it is. Inside it has just a 64K RAM card in the AUX slot, maybe a double hi-res card. Do I need to get a 128K card for one of the expansion slots? I've also had some conflicting information that the //e has 64K on-board and using a 64K AUX card should work, but these games don't work. I think I should just get a 128K RAM card and be done with this.
  2. Anyone use the N64 Ultra HDMI kit? How is it?

  3. Well, it doesn’t seem to be moving too fast. Toss me a PM if you’ve decided.
  4. I got it from (I think) jelloslug on pcenginefx before the forum closed. See this thread: https://www.pcenginefx.com/forums/index.php?topic=18611.0
  5. Shipping only to Canada and USA, Paypal only, Prices are in USD. --- PC Engine Duo system, the original black model. It's fully recapped with a console5 smd cap kit, with a new super capacitor for saving and an RGB amp mod + 8 pin DIN socket. It needed wires to fix a couple corroded vias from the original capacitors. The DC jack was replaced with a smaller socket to fit more common power adapters. It has a new 3D printed card slot cover. The CD drive hasn't been touched but works great. Console is fully tested, good audio from the AV port and the headphone jack. Comes with PSU, matching controller, AV cable and RGB SCART cable. Also includes 3 loose hucard games Victory Run, Legend of Hero Tonma, Be Ball SOLD $270 USD shipped to Canada and USA SOLD Pictures: https://i.imgur.com/ORU8Nat.jpg https://i.imgur.com/Gn4dpeV.jpg https://i.imgur.com/CSLdcSo.jpg https://i.imgur.com/TFbteBy.jpg https://i.imgur.com/WIA2cdy.jpg Composite video: RGB converted to component video: https://i.imgur.com/YmF1eVH.jpg https://i.imgur.com/usbcrms.jpg PCE card and CD games in cases.

  6. I tried the checkout at arcadecomponents.com and their postage to Canada is very reasonable $8.50 USD), so I went ahead and ordered a CO10444 TIA and since it was on sale, a CO10745 6507 CPU too.
  7. Did nobody notice the mention of Atari-style joysticks here? Last I checked, you can't get easily get those to work on later IBM PC compatibles. The focus here should mainly be on gameport controllers (DB15). I don't think there's a particularly easy option for a computer like this. If you had DOS drivers for the PCMCIA / CardBus / PC Card slots, then a Gameport card would work. Parallel port to gameport would be a pain in the ass.
  8. Unless the game uses SRAM for game code (very rare in SNES games), then the only answer here is the Mask ROM. Do you by any chance have another SNES to test the game on?
  9. So, the game doesn't boot then, just a black screen? PCB has no apparent damage? Probably a bad Mask ROM then. Yes, they can go bad. A friend of mine mailed me a non-working Super Metroid, the first print version with 3 Mask ROMs in it, the PCB was in amazing condition. After extensive tests (dumped game, examined ROM in hex editor), I found that ROMs 1 and 2 out of 3 had gone bad. The last ROM was still good, just had to burn EPROMs to replace the first two ROMs. The specific nature of failure was the first two Mask ROMs appeared to have a stuck lower data line, internal failure. The game's (Super Metroid) SNS header said "Sspprrmmttoodd", the header is located at the beginning of the first Mask ROM. Also, ROMs 1 and 2 were made by Toshiba, the 3rd one was by Hitachi.
  10. He said the game boots to a black screen and the intro music plays. Sometimes the game displays the anti-piracy screen. I don't think the problem lies in the edge connector/trace area. It sounds more like a ROM/SRAM problem. The SNES cartridge slot is what some would call "OneBus", everything in the SNES has to share and take turns with the cartridge slot. A broken trace or a failing Mask ROM usually renders the game unbootable. This is unlike the NES which has two ROM buses in the cartridge slot, one for the CPU and one for the PPU. In a system like this, it's always possible to have a bootable game with graphical glitches. The PPU doesn't care if it's receiving graphics or not, but the CPU must get usable code or it can't work. The CPU also generates the music in the NES.
  11. Actually, the DKC Trilogy and a lot of other SNES games will specifically check for SRAM more than what's installed on the retail cartridge. This is because many popular copier devices back in the day used much larger SRAM chips for holding data. The way the game is behaving could be bad SRAM or a bad Mask ROM. Assuming there's no damage on the PCB, the ideal option would be to dump the cartridge and examine the ROM in a hex editor against a known good ROM. This is the only sure-fire way to know if the Mask ROM is actually bad. In SNES carts, very seldom is discrete logic used to decode larger Mask ROMs, which can be another point of failure in cartridge games. This device is very inexpensive and dumps both ROM and SRAM in SNES games very easily. It's a vital cartridge diagnostic tool. It even has an option to show you the game's SNS header, so you can immediately see if the ROM is mangled or not.
  12. I'll try to get some pictures or a video to better describe this. Some time ago I bought an Atari 2600 Jr console (short rainbow version). It was sold as having graphical glitches with every game. I cleaned the cartridge slot very well. As of this time I've only tested the console with Armor Ambush. In Armor Ambush, the game is visually sound, but on-screen action has problems. When moving either tank anywhere onscreen, they will flicker between the left and right halves of the playfield. Firing the cannon on either tank results in an instant hit no matter where the tanks are or where they're facing. I think what's going on is there's problems with the playfield, players and missiles working properly in relation to the TV output. I don't think the CPU has anything to do with what's going on. Can anyone wager a guess on which chip is failing here? I could also use a suggestion on where to buy replacement parts. I know arcadecomponents.com has 2600 Jr chips, but they might not ship to Canada.
  13. Accurate to the original hardware the games were designed for? In the case of the NES, a real 2A03 CPU and real 2C02 PPU. The analog side of the NES cannot degrade the quality of the core digital functions of the console. An original NES will play an NES game perfectly because it has the true CPU and PPU the game was coded for. Single chip clones that integrate the CPU and PPU in an ASIC can also perfectly play NES games. That said, just like the original hardware, the superficial quality can vary. FPGA based clones like the RetroUSB AVS are much the same. Software emulators instruct an incompatible CPU to act like a different one. This conversion works precisely like a weighted scale. The more accuracy you want, the slower the framerate will be. Ever heard of the DICE emulator? It runs Pong with perfect transistor-level accuracy and requires an insanely overpowered PC to run at full speed. Please read this article before mindlessly bashing real hardware purists. http://arstechnica.com/gaming/2011/08/accuracy-takes-power-one-mans-3ghz-quest-to-build-a-perfect-snes-emulator/ Because a game ROM is not playable unless it is executed by the hardware it was written for, isn't it logical to conclude that the hardware is what matters most?
  14. I am willing to trade a little convenience for full accuracy. Granted, sticking with original hardware does depend heavily on keeping CRTs around, but I'm not a TV snob, my only TVs are CRTs. I don't believe in today's HD nonsense.
  15. Looks like I'm the one to post the unpopular opinion. I really despise emulation, it is almost never 100% accurate. ROMs are not functional games until they are executed. Realizing that, shouldn't the most important factor be the "executing" part? That's why I am pro-original hardware and the occasional clone hardware (single chip type varieties, not software emulators). I am however not against ROMs. As stated above, a ROM is just a set of instructions. As long as the ROM is not damaged, it will be played as the correct game if used on accurate hardware. The container of the ROM is completely meaningless, be it a cartridge or digital file. I am a huge fan of flash carts and modchips. They make classic gaming so much better in the face of insane game prices.
  16. bump, Castlevania 2 Redaction NES sold.
  17. Bump, added a Bandai WonderSwan SwanCrystal system.
  18. nothing for sale currently, thanks for looking.
  19. 5200 bundle, 2600 cartridge lot and 2600 papers are sold. (how do I edit the original thread?)

For Sale If you don't like my prices for whatever reason, I do take offers. Atari 2600 I'm not up to date on pricing Atari stuff in general so feel free to make offers. I'm more than happy to bundle things together if you want a console and a pile of games. Atari 2600 Jr. system bundle. Included are the 2600 Jr. console, two official joysticks, two official paddles. AC adapter, RF cable and a copy of Asteroids. (Asteroids is pictured in with the mass 2600 cart pictures). All items are in good condition. The paddles are a bit jittery, but otherwise everything works well too. $40 Coleco Gemini system bundle. Included are the Gemini console, one official Gemini controller, two "Dual Command" controllers, Sears Video Arcade II controller, AC adapter, RF cable and a copy of Asteroids (again, pictured in with the mass 2600 cart pictures). Everything works good, yes even the paddles on the combo controllers. The RF port on the Gemini is a bit finicky but works. $40 Assorted Atari 2600 games. They're in varying condition but all work. Can pair with either of the system bundles for a discount. Two of the Asteroids carts pictured are part of the system bundles above. $55 List of games: Space invaders, Night Driver, Enduro, Chopper Command, Adventure, Midnight Magic, Mario Bros and Armor Ambush are taken Assorted Atari 2600 booklets and papers. Can include with the games or systems if you want them. Also have a couple 2600 cart holders I can include with the systems or all the cartridges, for the cost of shipping. By this I mean you'll pay more in shipping if I include either of these cart holders. *second pic coming soon* http://i1094.photobucket.com/albums/i458/SirGuntz/DSC08197.jpg Atari 5200 Atari 5200 system bundle. Included are a 5200 2-port console, two official controllers, 2600 Adapter, AC adapter and 9 games (got a few duplicates). Both controllers work fine for me, you can start, pause, fire buttons and keypads. They aren't refurbished though so I can't guarantee they will work for you. The other items included are tested working and in good condition. Console still has its controller compartment cover and silver faceplate. Some booklets and controller overlays are included and pictured. $75 (shipping will be about $40 to the US, I can get an accurate quote if interested) List of games (the extra copies have bad labels btw): http://i1094.photobucket.com/albums/i458/SirGuntz/DSC08186.jpg http://i1094.photobucket.com/albums/i458/SirGuntz/DSC08181.jpg http://i1094.photobucket.com/albums/i458/SirGuntz/DSC08182.jpg http://i1094.photobucket.com/albums/i458/SirGuntz/DSC08184.jpg http://i1094.photobucket.com/albums/i458/SirGuntz/DSC08185.jpg http://i1094.photobucket.com/albums/i458/SirGuntz/DSC08188.jpg http://i1094.photobucket.com/albums/i458/SirGuntz/DSC08198.jpg http://i1094.photobucket.com/albums/i458/SirGuntz/DSC08196.jpg Famicom/NES Dragon Ball Z III: Killer Androids, English translated.

Each copy is in varying condition but overall good, some crushing here and there. 5 copies available $20 Each Wii Metroid Prime 3 Corruption, brand new and sealed. In very good shape overall. $45 PC Windows / MS-DOS As far as I can tell, these are all CIB, but I'm not an expert with big box PC games. They all have a cardboard tray, box, jewel case and game, among other things. I might be able to fold some of these for cheaper shipping. Most of these are CD-ROM, a couple are 3.5" floppy. Want them all? I'll cut you a very nice deal, you'd basically just be paying for shipping Sim City, not sure which version it is. It's on a CD-ROM so it's probably a re-release. Includes the box, folding cardboard insert thing, some warning card and the Sim City jewel case, which is cracked. $10 Half-Life: Blue Shift, seems to be pretty much complete, has the box, tray, manual, other stuff and the jewel case with game. $20 Vigilance, includes box, tray, paperwork, jewel case and game. $7 Armour-Geddon, includes box, tray, paperwork, thick manual and 3 floppy disks. I think it's complete, if not really pretty, Psygnosis sure knows how to make a package. $20 Sim Tower, includes box, a bunch of paperwork and booklets and 3 floppy diskettes. Probably the first release since it's on floppy. $15 Zork Nemesis, includes box, puzzle-like tray, booklet and the jewel case. $10 SOLD /End of thread
  21. Yes, the computer works fine with another joystick, though it connects to an internal connector. The new joystick I got, I plugged into a 9 pin port on the back.
