[WiiU] PPC JIT Possible? #473

Open Ploggy opened 2 years ago

Ploggy commented 2 years ago

Would it be possible to add the PPCJIT that was added to E-UAE (which PUAE is based on)? https://sourceforge.net/projects/euaeppcjit/

Surely someone would have to make JIT work in general first..

Ploggy commented 2 years ago

In general? it doesn't work now?

EDIT: you mean on WiiU? in that case dynarec is now possible, Picodrive and Pcsx both support and use it on WiiU :)

sonninnos commented 2 years ago

On this core. It will not compile if JIT is enabled, so it needs fixing.

Ploggy commented 2 years ago

O.. :P that would be a problem :/

I'd honestly rather that the core updates to latest WinUAE upstream releases that have rewritten emulation of several subsystems. That would probably increase performance and reliability, not increase one and decrease the other.

Also JIT in WinUAE crashes all the time, especially when you use savestates. I think it's from the habit of amiga software using self-modifying code for 'speed' and only achieving 'bugs', combined with the lack of enough state saving in the JIT.

Besides, the WiiU should be more than enough to use the interpreter for a A1200 and that's 99% of games. There is a reason few people care about the JIT, if you're not trying to, say, run retroarch on a gamecube or something.

You'd think so eh? there's quite a few games that don't hit fullspeed on the WiiU with A1200 set and I doubt its a WiiU issue because like you said, the WiiU should be more than enough to get full speed from puae.
