Gameboy Advance Bios / GBA BiosSome Emulators require you to have a bios to operate. Gameboid is one of the few that does, so here is a quick guide to BIOS and a link to download it.
GBA Bios?The Gameboy Advance includes a small BIOS ROM (built-in in its CPU), the program code in this ROM is used for three purposes:
The Intro Sequence. Displays the Gameboy logo and Nintendo logo each time when the GBA is switched on.
The SWI Functions. Maths, initialization, decompression, and other functions, which can be used by GBA software.
Multiboot Function. Allows to boot the GBA from other computers or consoles even if no cartridge is inserted.
The original BIOS code is copyrighted by Nintendo, and for that reason, not included in the Gameboid Package.
