Stuttering audio in PCSX-reARMed core on linux

RetroArch General
#1

Hello

I’m running retroarch on a nettop system (er1401) which is addmittedly quite low spec and am having issues with the audio for the PCSX core. The gameplay appears to run fine but the audio is very glitchy. I’ve successfully run standalone PCSX-reloaded on this system under linux without issue, but would prefer to use a retroarch core to simplify input handling between emulators. Any ideas of what might improve the audio situation or is reARMed just not optimised enough for x86_64 to run correctly on such a low spec x86 machine?

Yeah, ReARMed is tuned specifically for (you guessed it) ARM. x86 should really use mednafen-psx, if possible, but that’s probably not going to work for you on a low-spec system. I’m afraid you might have fallen into the crack between these two cores :frowning:

There’s been talk of trying to merge some things from Reloaded into ReARMed to fix this coverage gap, but nothing has happened in that direction so far.

The issue here is that PCSX-ReARMed on PC uses an interpreter core, while PCSX-Reloaded comes with an x86 dynarec, which makes it run quite a bit faster.

I’ve been of the opinion that RetroArch should incorporate a PCSX-Reloaded core as a low-spec alternative to Mednafen on PC. The only issue is that the plugins that PCSX-Reloaded comes with kinda suck. If they could attach PCSX-ReARMed’s NEON GPU plugin onto it, however, it would be quite nice, but without the NEON extensions, it wouldn’t be too much faster than Mednafen, I would think.
