GameYob by Drienn is an open source Game Boy und Game Boy Color emulator for Nintendo DS and Nintendo DSi (via Sudokuhaxx).
– Savegame management has been modified to prevent corruption as reported by some.
– Autosaving is laggier due to the above. Consider turning it off.
– The configuration file has been moved from “gameyob.ini” to “gameyobds.ini” to prevent
conflicts with GameYob 3DS.
– A “single-screen mode” has been added.
