notes: |
|
|
Beetle VB is a port of Mednafen's Virtual Boy emulation module to
|
|
libretro. Based on Mednafen v0.9.36.1.
|
|
|
|
No external BIOS or firmware files are required. The Virtual Boy
|
|
hardware did not use a traditional boot ROM or BIOS in the way
|
|
that consoles like PlayStation or Saturn do. The V810 CPU starts
|
|
execution directly from the game ROM mapped at 0x07000000.
|
|
|
|
The core loads the ROM into GPROM (Game Pak ROM), mirrors it if
|
|
smaller than 64KB, and initializes 64KB of WRAM and optional
|
|
GPRAM (Game Pak RAM/SRAM for saves). The VIP (Virtual Image
|
|
Processor), VSU (Virtual Sound Unit), and hardware timer are all
|
|
emulated in software with no firmware dependencies.
|
|
|
|
The libretro .info file (mednafen_vb_libretro.info) declares no
|
|
firmware entries and no system files.
