Homebrew SPC on SNES APU!

[marshallh]

Finally, I got my converter to work! I forgot a ground wire... but its fixed.
This adapter lets you plug in a self-powered APU sound module from a Super Nintendo and load any SPC file from your computer onto it! As you can see, it works through the parallel port.



Right now I'm listening to some cracktro music. Good stuff! You can unplug the module once the song is done loading, and it loops infinitely.

This is the first stage of my Portable SPC Player. I'm going to use a PIC16F876 to load SPC files off a FAT16 formatted MMC memory card, and load them onto the APU module without a PC, sort of like my own SNES ipod.


If you're interested, I made a PCB for future users to build this, if you want. I didn't make the schematic, just built it and made the PCB above. If you want a high-res version or the ExpressPCB source, let me know.

Please don't hackaday or digg this quite yet, please wait until I get the actual portable version done.

Very neat, even though I don't understand anything you said.

you are definitly one smart dude Marshall i must say i wish i knew as much as you do about electronics this looks really cool though. i think i understand what you are doing but i am also semi clueless it looks cool though

I've seen this project before. I wanted to build it myself, but I only wanted to do it if I could find a way to use it with an emulator. THAT would be awesome! Listening to SPCs can be done with a simple Winamp plug-in. Given, it's a software emulation of the APU, but it's good enough for me. But... if I could actually play SNES games on my computer and listen to the sound through an actual hardware APU, that would make the project worth it. Any ideas on how I could do that? You're the software programmer, after all. Write me a plug-in for ZSNES!!

Edit: Yay! 300th post!
