GameYob v0.5.1 is released. GameYob is an open-source gameboy emulator for the DS. It has excellent compatibility and speed, and runs many games flawlessly. Notably, it can use the Gameboy Color bios to colorize pre-color games, just like on a real gameboy.

GameYob v0.5.1 Changelog:
- 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.
