I don't know about you guys and girls, but sometimes I like reminiscing about my childhood by playing some good old Mega Drive (Genesis for those across the pond) games. You can't beat a good round of Sonic.
When it comes to Mega Drive emulators that run on Ubuntu, Gens/GS rocks. Gens/GS is a fork of the well known Gens emulator, and over the last several months the author has been cleaning up the source code and adding new features and bug fixes to create an awesome (open source!) emulator.
Some of the features include:
- Multiple resolution support
- Lots of rendering modes
- Sega CD support
- SDL or OpenGL rendering backends
- Save/Load States
- ...and loads more!
The package only comes in the i386 flavour, so if you are running the AMD64 version of Ubuntu you may need to use dpkg and some --force-architecture magic:
sudo dpkg --force-architecture -i Gens_2.16.7_i386.deb
You'll get a Gens/GS entry under the Games menu where you can fire up your classic ROMS.
Note, the legality of running old ROMs is a grey area and depends on the laws in your country, so check them out first.
