Libretro port of O2EM, an Odyssey2/Videopac emulator by Daniel Boris
|
||
and André de la Rocha. Port by Arlindo M. de Oliveira.
|
||
|
||
One BIOS ROM selected via o2em_bios core option (default o2rom.bin).
|
||
Loaded into rom_table[0] (1024 bytes), identified by CRC32.
|
||
vpp=1 for Videopac+ variants (g7400.bin, jopac.bin).
|
||
Core fails to load without the selected BIOS.
|
||
|
||
Voice module ("The Voice" speech synthesis add-on) emulation via WAV
|
||
samples in system/voice/. 9 banks × 128 samples, named {bank}{sample}.WAV
|
||
(e.g. E480.WAV). Compiled with HAVE_VOICE=1 on most platforms. Optional:
|
||
core works without samples, speech is silently skipped.
