You may put games in games inside a subfolder for each core. You may also but BIOS files in the same folder as the ROMs for each system and name it boot.rom, if the core does not use a BIOS file you can rename a ROM file to boot.rom and it will autostart with that ROM. You may also just put BIOS or autostart ROMs in its own folder, see above for naming. Here is an example of folder names inside the games folder
