notes: |
|
|
O2EM is the libretro port of the Odyssey2/Videopac emulator.
|
|
The core requires exactly one BIOS ROM selected via the o2em_bios core option.
|
|
Default is o2rom.bin (Odyssey2 NTSC). The user can switch to c52.bin, g7400.bin
|
|
or jopac.bin for European/French Videopac variants.
|
|
|
|
BIOS files are loaded from the system directory into rom_table[0] (1024 bytes).
|
|
The core identifies the BIOS variant by CRC32 and sets the vpp flag accordingly
|
|
(vpp=1 enables Videopac+ enhanced graphics for g7400.bin and jopac.bin).
|
|
|
|
The core will not start without a valid BIOS file present.
|
|
Any single BIOS from the list below is sufficient for its region/hardware.
|
|
|
|
All BIOS files are exactly 1 KB (1024 bytes).
