emux is a multi-system emulator by Sebastien Ronsse, supporting CHIP-8,
Game Boy, NES, and Sega Master System as separate libretro cores.
emux is a multi-system emulator by Sebastien Ronsse. The libretro port
renamed the boot ROM from DMG_ROM.bin (upstream, gb_mapper.c:32) to
dmg_boot.bin (libretro, gb_mapper.c:35) to match RetroArch conventions.
Boot ROM loading in controllers/mapper/gb_mapper.c:
static char *bootrom_path = "dmg_boot.bin"; (line 32)
gb_mapper->bootrom = file_map(PATH_SYSTEM, bootrom_path, 0, BOOTROM_SIZE);
If file_map returns NULL, gb_mapper_init returns false — core cannot start.
No HLE fallback, no skip logic.
Boot ROM loaded via file_map(PATH_SYSTEM, "dmg_boot.bin", 0, 256) in
gb_mapper_init (gb_mapper.c:225-228). Returns false on failure — no HLE
fallback. Mapped at 0x0000-0x00FF, overlays ROM0 until BOOT_LOCK (0xFF50)
is written non-zero (lock_writeb, gb_mapper.c:97-106).
Boot ROM is 256 bytes (BOOTROM_SIZE in gb_mapper.h:10), mapped at 0x0000-0x00FF.
When register 0xFF50 (BOOT_LOCK) is written with non-zero, the bootrom region
is removed from the memory map (lock_writeb, gb_mapper.c:130-138).
Memory map from mach/gb.c:
0x0000-0x00FF Boot ROM (overlays ROM0 until BOOT_LOCK)
0x0000-0x3FFF ROM bank 0 (16 KB)
0x4000-0x7FFF ROM bank 1 (switchable, 16 KB)
0x8000-0x9FFF VRAM (8 KB)
0xA000-0xBFFF External RAM (8 KB)
0xC000-0xDFFF WRAM (8 KB)
0xFE00-0xFE9F OAM (160 bytes)
0xFF80-0xFFFE HRAM (127 bytes)
The .info declares firmware_count=1, firmware0_opt=false.
is_experimental=true. Core does not support save states, rewind, or netplay.
system_directory obtained via RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY
(libretro/libretro.c:23-25), passed as "system-dir" config param.
No hash validation. Code accepts any 256+ byte file.
is_experimental=true. No save states, rewind, or netplay.
