Snes9x 20 Plus are the best ones so far availble on the Vita Otherwise you will lose savegames whenever you close RetroArch through the Vita launcher.Įdit2: If you're disappointed about the lack of shaders btw, I recommend you enable the Scanlines Alpha overlay, which can be enabled under "Quick menu > On-Screen Overlay > /data/retroarch/overlays/ctr/effects/scanlines-alpha.cfg". I hope this post helps some people the headache of trying to run games through RetroArch!Įdit: To avoid losing savegames when not properly exiting RetroArch via the "Quit RetroArch" function, you should enable automatic SaveRAM autosaving, under "Settings > Saving > SaveRAM Autosave Interval", setting it to a sensible value like every 3 seconds. Certain 3D titles like Doom or Duke Nukem will however still suffer from severe slowdowns. gbSP runs even more complex titles like F-Zero Climax with no issues on stock clock. SNES seems to be the only system that requires overclocking. Even without overclocking most games are playable, though you do get some sound stutters in Mario World and massive slowdowns in mode-7 heavy games like F-Zero or Yoshi's Island. SNES games run mostly fine using SNES9x 2005 Plus, but most games require slight overclocking from 444 to 500MHz to get rid of occasional framedips, which you can do by hitting Select+Up to open the PSVshell overlay (which you probably unknowingly installed during the intial Ensō setup - just try if the button combination works).
The cores that worked best (pretty much full speed with no noticable issues across all games I've tested) were FCEUmm for NES, gbSP for GBA, Gambatte for GB/GBC and Genesis Plus GX for Megadrive.
If anybody has been a little overwhelmed and disappointed by RetroArch's plethora and performance of cores, I thought I'd share my recommendations, after trying them out for a few days.
