- Memory card with FMCB (Free Memory Card Boot)
- USB drive and homebrew BIOS dumper like
BIOS Dumper
Once booted into uLaunchELF:
- Copy the BIOS file from
mc0:/BIOS/or use a dedicated dumper tool. - The output will typically be several files (
rom0,rom1,erom, etc.) that PCSX2 can combine or use individually.
