Most of the questions have been about pricing, I can say for sure that the Playchoice boards will cost a little more to make than the NES boards. Estimating $7 more. New NES games usually are around $35, so you can say maybe $42~$45 for decent quality games (512kB memory). I only supply the...

Long ago I did an experiment to run my NES code in MAME, and that did work. I think I had to compile my own build of MAME to make it load my "bad" ROM with a warning rather than an error. But that was back in the early 00's, maybe MAME now has some kind of option or debug version. However, I...

1500points: I assume you're asking if it will run on a PC10 with a modified BIOS? After comparing the name/instruction ROM format, I think so. But I haven't tested that yet. Paul Olson: With the demo version I know that is possible, but there is the normal NES demo version, of course. For...

Maybe Blood Bros.? It's kind of a western-themed version of Cabal, developed by the same company.

Robotron-inspired shooter coming to Nintendo Playchoice I wanted to tell you guys about a game my friend is writing for NES, which will also be one of the first new (non-bootleg) releases for the Playchoice It's on Kickstarter and is fully funded and mostly developed. We don't have the...

I have a random last-minute request.. is there anyone who is attending MGC who has an NES-to-Playchoice adapter that I could borrow during the show? It would need to be the type that works with the factory-original Nintendo BIOS. If someone can do this, I'll repay you with a PC10-related gift...

Cool, I'm glad that hack is being enjoyed. Do thank lilman also, I only investigated it because he was interested and making an effort (and it's not easy to hack 6502 assembly if you don't know it, heheh). After explaining it though, since I have a VS, and like Tecmo's NES stuff, I became too...

All the colors are there, but on the 2C04 PPUs they are in a different order. Some games in fact check the dip switches to let you select the palette type. 2C03 is the 'normal' one as used in the Playchoice. The 2C05 I suppose was an exaggeration for me to say it'd be fairly simple (if you...

Just FYI, you don't actually need any universal PPU to run every VS game. Just a fairly simple hack of the game ROMs is all that's needed to break the "protection". In fact, with a list of addresses to patch, one could run any given VS game on any given PPU model. It's not hard to hack the...

Not like that (disconnecting 5V), because the EPROM's data lines could end up becoming the power supply for the circuit instead. If you disconnect the data lines, maybe. I don't know if the address and control lines could interfere, but maybe. To me, it sounds easier and safer to simply...

I checked the manual (it's on page 42), it's C3 - 10uF 20V.

Fast Food. I liked it enough to eventually make a clone of it, called Munchie Attack (not as good as the original). Midnight Magic Enduro Plaque Attack Millipede Missile Command Freeway

Total idiocy. My hometown of Indianapolis became world famous about 10 years ago, when they tried to do the same thing here (ban "violent" arcade games from being where kids can access them). The end result was the city wasted a lot money between doing studies, losing their case, appealing the...

It's probably worth noting that Millipede only does the RAM/beep test if you have the DIP switch set to test mode. If I recall correctly..

No, there's something like a bandpass filter so it won't detect light that's outside of the 15khz horizontal refresh rate of the monitor. Besides, it's unpredictable what a game would do if it was constantly detecting a hit. Especially if there's more than 1 target. If anyone wants to test...

Did anyone get to see these? Seller never contacted me, I was ready to go Thursday but I guess that was too late. Was hoping to get Life Force and Contra, or at least something I could fix, but oh well. I don't check CL much anymore, so it was interesting to stumble into that ad. I did look...

I doubt you'll find a source for the custom parts (MMC1, MMC3), other than cannibalizing other boards. I do know of clones for both those chips, I've never tested the MMC1 one, but the MMC3 one is in a huge DIP-40 package and wouldn't fit very easily on a standard-sized Playchoice board. Of...

It depends if you are able to desolder parts without damaging the board, and if you consider it a hassle to locate/order replacement parts. I would try replacing the 74S04 (or whatever type of 74x04 there) that's connected to the crystal (the 21.47727Mhz one), but after checking the voltage on...

That is interesting, the sound is 100% digital and created in the NES' CPU (RP2A03). The only way I know of to increase the audio pitch would be to send a faster clock to the CPU. The same clock also runs the PPU, but a CPU problem alone could create graphical glitches as well. Maybe...

I asked a friend of mine, and he speculated it could be a bad chip. Do you have an EPROM burner? If so, you could run an NES test program (same one used at Nintendo service centers). This would reveal the problem if it's in the PPU or VRAM. If it's not clear, take a pictures of the glitches...
