notes: |
|
|
Libretro port by Zoltan Balogh of Tom Seddon's b2 BBC Micro emulator.
|
|
is_experimental=true in .info.
|
|
ref: zoltanvb/b2-libretro, tom-seddon/b2
|
|
|
|
Standalone loads ROMs from etc/roms/ via GetAssetPath() + LoadFile().
|
|
ref: tom-seddon/b2/src/b2/roms.cpp:9-10
|
|
|
|
Libretro port embeds all ROMs as hex arrays in src/libretro/roms.hpp.
|
|
create_core() loads OS and sideways ROMs from static machine_types[] arrays.
|
|
GetAssetPath() and LoadFile() are stubbed — no file I/O at runtime.
