Re: Getting a Disk System to work on a Playchoice 10

Have you tried to/needed to implement any of the PC10 hardware fixes? There is a flaw with some PC10 boards that requires a fix to implement some compatibility with games such as Mario 3. I'm at work, and we have youtube blocked, so I cannot see what model of PlayChoice you are running. Yep, I'm ru...

Re: Help fixing sound issues? Hyundai Comboy (South Korean N

Well diagnosed! I removed the cpu and installed it into a famicom which was just showing a black screen (guessed cpu). The comboy cpu brought the famicom back to life and took the sound faults with it, so now I just need a cpu for the comboy. Turns out my scrap famicoms all have bad cpus so that suc...

Re: Getting a Disk System to work on a Playchoice 10

Here's a video: https://youtu.be/O_hgfbY4k_Y That one's a pretty minor one but you get the idea. I was using the fdsemu that time which is why the disc read happens so fast. I'm using gamehacker's bios, that shouldnt be a problem though should it? I was in a hurry so i forgot to video this but if I ...

Getting a Disk System to work on a Playchoice 10

Hello, I have one of 2600's Nes to Playchoice cartridge adapters, and I would like to get it working with the fds ram adapter and my fdsemu. At the moment it works up until the fds "bios" tries to hand over to the game. This causes the screen to scramble a bit and thats all. Same deal with an actual...

Re: Help fixing sound issues? Hyundai Comboy (South Korean N

LiveNES is a just a tiny minimalist thing that you could stuff into any cart with CHR RAM and a 4 KiB (or larger) PRG ROM. It doesn't use any banking, so it should sit ok on almost any hardware. The ROM will need repacking to fit into a smaller ROM (it comes by default as a full 16 KiB image, with ...

Re: Help fixing sound issues? Hyundai Comboy (South Korean N

Um. The triangle is out of tune with the pulse waves, and the values written to the noise channel seem to be broken in some other novel way... as though it can't ever turn it off? It vaguely sounds like one of the bits in the triangle period is forced set? Comparing your recording to the NSF, somet...

Help fixing sound issues? Hyundai Comboy (South Korean NES)

I am the proud new owner of the yellowest of yellowed Hyundai Comboy consoles:)
It has a sound issue which I suspect will be easy to fix once I know what I'm looking for.
Here's a video:

Anyone know where I should start?

Cheers,
