It is possible to enable fast forwarding on Game Boy games. There are plenty of options to mess around on Retroarch. KMFDManic tipically calls thes folder _dummy, hence the method name. It consists in having the games inside a folder and using the Load Content option on Retroarch.

It is a method used by KMFDManic to load games. etc/libretro/joypad_autoconf - where joypad configurations are stored (?). etc/libretro/config - where options, overrides, and remaps are stored. Overrides, on the /overrides folder, and overlays, in the /overlays folder, don't get deleted. When Retroarch is updated from a previous, compatible version, the files retroarch.cfg (regarding global options when no override is in place ?), and retroarch-core-options.cfg (regarding core-specific options, in Quick Menu -> Option, when no override is in place ?) get overwritten by default files.
