SNES Emulation

Killswitch · Post by **Killswitch** » Thu Sep 28, 2006 7:06 pm

I've been thinking abotu starting to write a SNES emulator in PB. I think I could manage it and, if I can't, it couldn't hurt to try

. I'm just having a bit of trouble actually finding some resources to help me along.

I've been trawling google and wikipedia for a while and I haven't managed to turn up much (there was one page with a lot of resources for the NES, however).

Downloading an disecting the source for an existing emulator doesn't really appeal to me, it's fairly hard to learn from if it's complex enough.

Anyway, I wondered if anyone here could help me out?

Very Cool!

BalrogSoft (sp?) wrote an emulator years back in PB, but I think it was a gameboy one.

I know you don't want to dig in the code of an existing one, but how about a compromise? At Planet Source Code, in the VB section there are a couple of different emulators in various stages of development. Again, I think these are mostly GameBoy oriented, but there might be a NES or SNES one in there. Either way, you could probably learn something about emulation from them and VB code is easier to sift through than C++ code.

Just a thought...

Thanks Trond but it's not exactly what I was looking for. A more in depth look into emulation of the SNES would be handy. (Not being ungrateful

)

I know what you're looking for, but I don't think it exists. So I thought, if you know the thing works (i.e. the link gives you a list of registers) you would be able to emulate it.

Nice.
But i would very lazy doing heavy duties just to reinvent the wheel.
Killswitch, i suppose you know this:
http://zsnes.ipherswipsite.com/
It is more than perfect and it is written in ASM.
I feel nice just knowing there are people in the world who are able to program these things and so perfectly.

BTW, have you tried this for PSX:
http://psxemulator.gazaxian.com/

It is the best one until now for PSX.

Charles McDonald's website is the best ressource for who want to code an emulator, you also have Caesar for cpu related opcode table, timing etc ..., here you will find info for rom id header company and the last but not least, this forum where you can find almost all emulator coders.
Note that coding a snes emu is possible, there is no PB limitation in this domain but if i were you, i might begin with a simpler hardware like Chip8 (allready done by Balrog) or a NES/SMS/Spectrum.
I allready have a place in my head coding an emulator ... a pc engine emu in PB, who know, if i find enough spare time
