ApprenticeMinusDS ist ein Sega Master System /GameGear Emulator für den Nintendo DS.
This version has scaling support for Gamegear mode and a region selection option, to enable playing of multi-region games in non-Japanese mode.
The hardware renderer was completely rewritten to support the scaling, but there was not enough time to test it, and there are some known (and unknown bugs) that i introduced, that will be fixed as soon as possible. Mostly it should be fine though. See the readme for more info on known issues and how to get around them, if possible.
