My work schedule has made it difficult to find time to write regular updates, but I'll do my best to ensure that emulation.net will be updated frequently in the future. This version corrects a variety of emulation bugs. Since this version is a release candidate, MacMAME 0.35 final will most likely be released in week or two. NeoMAME PPC is a version of MacMAME which is optimized solely for Neo-Geo games. This version is even faster than before.
Future versions promise improved scrolling, save-RAM support and better compatibility.
The author of GenEm is considering bringing the project back to life. He's asking for donations to spur his interest in the project. If you enjoyed GenEm, it's certainly a worthy cause. It also adds an improved floppy drive emulator which apparently supports disk images. Power PC Engine has been updated to version 0.4b1.
