Gambatte is a Game Boy / Game Boy Color emulator focused on accuracy.
No BIOS is required for normal operation. The core has a built-in
HLE boot sequence that skips the Nintendo logo animation by default.
Accuracy-focused GB/GBC emulator. No BIOS required for normal operation;
built-in HLE boot sequence skips the Nintendo logo animation.
When the core option "gambatte_gb_bootloader" is set to "enabled"
(the default), the core looks for official boot ROMs in the system
directory to play the real startup logo animation. If the files are
missing, emulation still works without them.
Core option gambatte_gb_bootloader (default: enabled) enables loading
official boot ROMs from the system directory for the real startup animation.
If missing, emulation works without them.
The boot ROM loaded depends on the hardware mode:
- DMG (original Game Boy): gb_bios.bin (256 bytes, 0x100)
- CGB (Game Boy Color) or GBA mode: gbc_bios.bin (2304 bytes, 0x900)
Boot ROM selection by hardware mode:
- DMG: gb_bios.bin (256 bytes)
- CGB or GBA: gbc_bios.bin (2304 bytes)
In GBA mode the core patches the CGB boot ROM at 0xF2 to fake
GBA detection (ld b,0x01), enabling GBA-enhanced features in
compatible GBC games (Shantae, Zelda Oracle series, etc.).
In GBA mode the core patches the CGB boot ROM at 0xF2 to fake GBA
detection (ld b,0x01), enabling GBA-enhanced features in compatible
GBC games.
File path construction: libretro.cpp get_bootloader_from_file()
joins RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY with each filename
directly - no subdirectories.
The upstream standalone supports SGB boot ROM loading; the libretro
port does not implement this.
Gambatte does NOT use sgb_bios.bin. The SGB palette references in
the source are color lookup tables for DMG palette colorization,
not actual Super Game Boy boot ROM loading.
Custom palette files (palettes/*.pal) are user-created colorization
configs loaded when GB Colorization is set to "custom". These are
user-generated content, not distributable files.
