Catridge using msu1

Post by olddb »

I understand more or less how the chip works on an emulator, but how would you acquire/make the hardware for the real thing? :?: :?: :?:

Ah.

I meant like if I you were to produce a msu1 game, for example. How would you go about buying/producing the chip?

Thanks for the reply.

As of now, releasing digitally for play in higan, or SD2SNES is really the only option.

You'd have to emulate it using an FPGA or a CPLD. You may be able to use a modified version of the core from the SD2SNES as a start.

An alternative might be to use software emulation on a cheap ARM core to emulate the chip on a cartridge.

Did byuu released the chip schematics?

Did he ever actually produced one?

No, as far as I know he really only designed it from the software standpoint.

Ikari integrated it into the SD2SNES design, which is open source so you could use that to help you design your own dedicated MSU-1 board if you wanted. This hasn't been done by anyone yet AFAIK, so you'll have to do it yourself.

This should get you started if you know Verilog: https://github.com/mrehkopf/sd2snes/blo ... snes/msu.v
