notes: |
|
|
Gearboy is a Game Boy / Game Boy Color emulator by drhelius (Ignacio Sanchez).
|
|
The buildbot builds from drhelius/Gearboy (upstream), not from libretro/Gearboy,
|
|
an archived fork (its description reads "NOTE: PUBLIC ARCHIVE") whose
|
|
src/definitions.h states version 2.6.0.
|
|
Bootrom loading is gated behind core options (disabled by default).
|
|
Without bootroms, the core HLE-skips the boot animation.
|
|
|
|
Super Game Boy mode (core option gearboy_sgb, enabled by default, one
|
|
instance only) reads the SNES cartridge ROM of the Super Game Boy,
|
|
SGB1.sfc then SGB2.sfc in the system directory. Only its default border
|
|
and palettes are taken from it, and SGB games run without it on the
|
|
built-in defaults. The ROM is identified by CRC32 and size against four
|
|
known dumps, whichever of the two names it carries, and an unknown dump
|
|
is refused (src/SGB.cpp:38-44, 200-223, 1096-1105).
