jEnesisDS

jEnesisDS has had its period of fame and notoriety, but the program was abandoned after its last version was released in 2008. In other words, bug reports or updates are less likely to help. However, the emulator is still available over the Internet and it does a pretty good job at emulating Sega Mega Drive games. The emulator is designed for Nintendo DS and it represents an upgraded version of the old emulator jEnesis. The developer was inspired by jEnesis, but the code was rewritten from scratch – from Java to C and ARM. Since Sega Mega Drive features a higher resolution than what you can get on Nintendo DS, the screen will be cropped on all edges.

The emulator was rewritten by Stephan Dittrich, who was hired by Sega to come up with an emulator for the Sonic Classic Collection. The new version – jEnesisDS – aims to fix the resolution issue.
