  • Rom Folder: PS
  • Extensions: .chd .pbp .bin/.cue .img .mdf .toc .cbn .m3u .ccd (must be lowercase)

Roms in .bin format must have accompanying .cue files or they will not be displayed.
Onion can generate .cue files automatically (Apps > Tweaks > Tools > Generate Cue Files for PSX Games).
Alternatively, you can create .cue files using a free online tool such as cue-maker.

All Bios files are 512kb in size and are case sensitive, they must be named exactly as shown above.
Using the PSXONPSP660.bin bios is recommended for best compatibility.
If you experience issues loading games, you can use md5 checker to verify your bios files against the md5sum provided in the official core documentation.

note

Concerning multidisc games : Since Onion 4.3.0 Tweaks app contains a multidisc playlist (.m3u) generator so no need to create your m3u files manually or to convert your multidisc roms to .pbp anymore. More info here.

Notes on performance​

  • Most of PSX games run at 60 FPS natively on the Miyoo Mini. For most demanding games you'll find solutions here to run it at full speed.
  • Rewind and Fast Forward capability should be disabled while playing PSX as performance may suffer greatly.
  • PAL/EUR games run at 50fps, NTSC/USA/JP games run at 60fps. This is by design and as per original hardware.
  • Some titles (e.g. Looney Tunes Sheep Rider, Jedi Power Battles, and 2xtreme/espn extreme games) need to have SMC Checks disabled or games will eventually slow down and crash. Go to RetroArch Quick Menu (MENU+SELECT while in-game), select Options and toggle on (Speed Hack) Disable SMC Checks.
  • PCSX-ReARMed standalone offer better performances than the default RetroArch core (see below for details)
  • overclocking is also an excellent way to improve PCSX-ReARMed performances on most demanding games. More information in the FAQ.

Notes on PCSX-ReARMed standalone​

PCSX-ReARMed standalone (not a RetroArch core but the classical emulator) offers much improved performances. It allows for using enhanced resolution in most games. However its integration in Onion is not perfect : no automatic save states, no resume at boot , different shortcuts...

Notes on Duckstation/SwanStation​

Duckstation is a core from Expert section compiled by KMFD. It is slower than PCSX, however it allows to run some games like Fromage. Could be interesting on rhythm games too.
