If you’re using RetroArch on your PS Vita (or PS TV), you’ve likely encountered the dreaded “missing BIOS” message when trying to run certain cores. Unlike cartridge-based consoles, systems like the PlayStation 1 (PSX), Neo Geo, Sega CD, and PC Engine CD require original BIOS files to function correctly.
Legal note: You must dump BIOS files from hardware you own. Distribution is copyright-protected, so no direct links can be provided. bios files for retroarch ps vita link
