Cemu and RPCS3 were already mentioned in the other thread but I didn’t know about Xemu.

I know these are still very early -more of a “proof of concept” and that for now the RA folks would rather not make any big announcement (and I agree) but if one day these cores become fully mature that’d be awesome for RA.

I tested the xemu core and it’s extremely promising (though I did stumbled on a few issues)

Bios/system boot screen:

Pinball Hall of Fame - The Gottlieb Collection:

If you want to try it out (experimental/proof of concept only keep in mind)

First, it’s probably a good idea when testing experimental cores like these to do this not in your normal RetroArch folder. So extract RA to another clean/new folder somewhere else to test there.

You will need 4 bios/files (obviously these don’t come with the core or Xemu and you’re supposed to dump them yourself) - the same ones as standalone Xemu except maybe the naming is not 100% identical. You can see what files (and what filenames) are required by loading the core then going into ‘core information’ -this will tell you if the files are being detected or not (if not if will say ‘missing’)

Place all four files in the same folder somewhere then create a ‘xemu’ folder in the RA ‘system’ folder and place the files there, then create a ‘bios’ folder, place it in the system folder again and copy all 4 files there once again, yes it’s weird having both folders with the same files but doing otherwise didn’t work.

edit: Regarding Xenia, it looks like the github page did not have a build/package or anything so obviously could not test it.

Xemu is very interesting to me because the standalone doesn’t support CHD so if this core is anywhere near as good, compatibility wise, i would gladly use that as my main XBOX emulator.

Regarding the alpha experimental Xemu core…compatibility seems unfortunately very low so far. Tested 5 or 6 games afterward and none of them worked and these are games like Panzer Dragoon Orta that worked for me on Xemu. The only game that went anywhere was Pinball Hall of Fame -first and only game I tried initially.

Other games only went so far as showing the Xbox Intro and being stuck here

while Orta went as far as booting and showing the Sega logo and the dev’s logo

then crashing (illegal instruction error of some kind)

xemu error

Some kind of shader problem it looks like. Again, plays fine on the same PC with Xemu.

So yeah, still has way to go but I do hope the core makes progress in the future.




Edit: Whoa:

Desktop running in window captures:

fullscreen RA screenshot captures:

Okay, never mind the above: it turns out Xemu apparently needs a specific dump/image format otherwise, the games don’t run (the format who does is much smaller in terms of size too).

So the core -even in alpha stage looks indeed very promising.
