View Full Version : Snes Emulator ports (xbox/360)

It's my understanding that Zsnes was once ported over to the original XBox, to run SNES games stored on the xbox's hard drive. It's also my understanding that the XBox 360 is capable of emulating the original xbox (that's how it does backwards compatability, much like the ps2 -> ps1, etc)

Does it stand to say, then, that an xbox 360 could be made to run SNES games, either by its own emulator or by making it emulate an xbox using zsnes?

Has anyone ever thought of this? Is anyone already working on such a project? Is this just a bad idea that would cause Microsoft's lawyers to point the chainsaw rifle from Gears at me (because xbox arcade already does some of this)?

Thought I would throw this out there. Anyone have any info?

Hm, is this true? I thought that it was just some kind of compatibility 'layer' or something.

It's my understanding that's how it does it: Software emulation. The ps2 simply had a ps1 emulator built in so that it could be backwards compatable. I think it's the same all around: no need to put two hardware sets into one board.

You are correct, the 360 does emulate the xbox in a sense. The problem is, it emulates the bog standard, unmodded xbox, so no chance of running anything but microsoft certified software through it.

Why on Earth would you want to do that? It'd be easier and faster to just make a native port of Snes9x, or even MESS when the emulation accuracy is good enough. Besides that, there's an on-going rewrite of ZSNES from ASM to C going on, which should make it portable enough to work on the Xbox 360.

Looks like the question's been answered. It's worth mentioning, though - my understanding of PS2 architecture is that it PS1 isn't emulated: it carries PS1 hardware. Hence the lack of upscaling, or any kind of improvement save texture filtering.

But I'm sure anyone who knows better will correct me if I'm wrong.

Yes, that's what I've always heard as well. The PS3 does not have this, (or at least has enough of it ripped out for the games to not be playable, ala Nintendo DS), so it needs emulation.

First gen PS3s had PS1/2 hardware built in but they removed it when they released it in Europe and now the newer one rely on emulation

Aaaah, that's right. Thanks for the correction.

Actually, from what I remember, the first gen PS3s had the combined EE+GS (same as found in the slim PS2) but not any PS1 hardware. The PS1 is weak enough that accurate emulation on the PS3 wouldn't be too hard. The PS2 is more challenging.
