Use4All2 Mod is an Amiga emulator for PS Vita. This is my mod of this great Amiga emulator that was originally ported to the Vita by Cpasjuste. Depending on when you read this, this mod might be ahead or behind his version.
Obtain and copy BIOS files kick13.rom (Amiga 500), and kick31.rom (Amiga 1200) to ux0:/data/uae4all/kickstarts.
Optional: copy over additional BIOS files kick12.rom, kick20.rom, kickcustom.rom (for e.g. version 3.1.4 or any other user-supplied BIOS) to the same folder.
