CrabEmu 0.1.2 Released!

Hot on the tail of version 0.1.1, I have just released CrabEmu 0.1.2. This release contains a rewritten Z80 core, modifiable controls, better rom loading (and the ability to load one rom after one has already been loaded), and a few other improvements.

As always, please report any bugs that appear, as I will be more than happy to try to fix them. :)

CrabEmu 0.1.0 Released

The first ever release of CrabEmu, a Sega Master System Emulator for MacOS X, was just posted this early morning. This release is pretty much untested except by me, so its probably chock full of bugs that need squashing. Feel free to test it out, and report any and all things that look like bugs to me through the Bugs tracker item. Enjoy the release.
