|
|
Libretro port of Mednafen's Saturn emulation module, frozen circa v0.9.45.1
|
|
(2017) with some later backports. Region auto-detection reads the disc header
|
|
and selects the matching BIOS. Manual override via beetle_saturn_region option.
|
|
|
|
InitCommon() returns false if the BIOS file is missing or not exactly 512 KB.
|
|
Both region BIOS files are required for full region coverage.
|
|
|
|
KOF95 and Ultraman ROM carts are loaded when the cart type is set via core
|
|
option or auto-detected from the internal game database.
|
|
|
|
Upstream Mednafen (1.32.x) has ST-V arcade board support (3 additional BIOS
|
|
files) and bootable ROM cart support, both absent from this libretro port.
