Porting To Original Xbox

RE: Porting To Original Xbox
Mm.... just reading up a little.

I never owned the first line of PSP but they only had 32mb of internal memory. Then PSP 2001 came out with 64mb of RAM but this extra RAM is to improve loading times. It does not improve performance gameplay etc... Games which came out the same time as the release of the PSP 2001 and PSP 3000 all work, and are compatible with the original PSP with its 32MB.

I would go ahead and try to run PPSSPP in X-DSL. Theroretically the PSP needs 32mb and the Xbox has 64mb and X-DSL use's about 10mb. That means you'd have 20mb spare.

Also, I don't know for sure, but maybe the Xbox RAM is a faster RAM than the one in the PSP. Also, I could be wrong, but doesn't the Xbox also use some virtual RAM on the hard drive (Yes it is slower) to help out with loading.

Of course, all of the above may not make a difference. I've never used Linux before. I might even try it myself once I've learnt how to do the basics like how to install PPSSPP and how to get it to run through X-DSL.

Where are you opening poster ???

I'm working my ass off for you here! Big Grin

RE: Porting To Original Xbox
Don't go spoiling my dreams! Tongue Henrik said it may be possible, in this thread. Both the Xbox 1 and Wii are listed as PPSSPP possible on the developent page too.

If it's do-able on the Wii (I'll start looking about to see if anyone is working on) then it should/may run on the Xbox 1.

If the OP decides to do a direct port, i'm here ready to test it, the OP and me love a challenge. Big Grin

RE: Porting To Original Xbox
Yeah, in X-DSL virtual memory will probably save you from the RAM problem.

However, I think the hardest issue will be GPU emulation. There isn't an OpenGL ES 2.0 implementation for the Xbox GPU, and it can't really support it fully either (it can do the vertex but not the pixel shaders). However most of the pixel shader setups for the PSP _can_ probably be emulated on the Xbox GPU, it does have ~pixel shader 1.4, it will be hard work though.

Again, I think it's likely to be just barely possible and really not worth the trouble Smile

RE: Porting To Original Xbox
Mm... Food for thought!

Maybe if you get some spare time you could re-write PPSSPP to use Direct3D instead Henrik? Smile

@Moderators - I'm only joking, this is not a request really! It's really not!!

So in a nutshell, the OP would need to port the opengl libaries onto a hacked Xbox. I have a feeling that the OP plans for his Xbox PPSSPP project weren't going to be as grand as this. Big Grin

Ok, thanks for the reply Henrik.

RE: Porting To Original Xbox
Im interested in this even if it only comes off as a proof of concept. Its always fun to see people try to do unique things.

I think a custom video rendered would need to be wrote and I also believe that a lot of whats wrote would need to be vastly optimized and very specific to the xbox.

Issue is no one really knows how to code in Assembler anymore and optimization aint like it use to be. Hell I mean this is a very very good emulator and its very fast but, then you turn around and we got jpcsp and that friggin wrote in Java and slow as crap. Why anyone would really atempt to make a emulator is java is beyond me.

Oh and im sure this topic is old as shit so sorry for a bump on and especially on my very first post.

RE: Porting To Original Xbox
There's plenty of assembler and jit code in PPSSPP. A lot of it has indeed been optimized.

There's a Direct3D 9 in-progress backend that was used for the Xbox 360 port. But, still would not hold high hopes of getting great performance.

RE: Porting To Original Xbox
Leaving GPU features aside, the main issues are the lack of RAM and CPU speed (64M and 733mhz Pentium-III-esque Celeron, iirc, so no SSE2). PPSSPP doesn't need a ton of RAM, but it usually uses at least 80-100MB on a PC, depending. Even with the rare RAM upgrade to 128MB, it'd still be pusing it.

3.8ghz i7 5930K, 16GB DDR4 RAM, 4GB Nvidia GTX 970, Asus X99 PRO, Windows 7 (SP1) x64

RE: Porting To Original Xbox
If you really want this I'm afraid you're gonna have to do it yourself, and it will only be able to play simpler games, and that only with the 128MB upgrade indeed, most likely. So it seems like way too much work for something that maybe 10 people will ever use. Most people have moved on from the original Xbox many years ago...
