Technical notes

SameDuck is the Mega Duck / Cougar Boy branch of SameBoy by LIJI32. Built from the SameDuck branch of the upstream repo (no separate libretro fork). The Mega Duck hardware has no boot ROM. All boot ROM loading functions are stubs in this branch (GB_load_boot_rom returns 0, request_boot_rom is empty, no BootROMs/ directory exists).

The libretro port loads only game ROMs via GB_load_rom(). No boot_rom_load_callback is set. retro_system_directory is stored but never used for file loading.

No BIOS or firmware files required. Generated on 2026-03-25T14:56:43Z
