Squirrel: The PlayStation emulation is developing very nicely. I've had no issues running any of the games I've tried. I can't get it to run CDs from the drive, but CD images work fine. This may be an issue with the libcdio library and Mac rather than an issue with Mednafen. The only other contender for PSX emulation on Mac (that I know of) is PCSX-Reloaded, but it hasn't been updated in a long time (not officially anyway). Mednafen also has the best emulation of Virtual Boy that I've found on any OS. Yeah, I know that it's a crap console that burns retinas and induces headaches, but Wario Land is still a good game.
It's very playable once you turn off the 3D and switch the colors to gray scale.
mossy_11: I'll try to release binary updates whenever another update is posted. However, if I fall behind, I've also got a compile script attached to the post I linked to earlier. Anyone with an install of Snow Leopard and Xcode can run the script inside the zip and compile a binary for 10.6+ users. Compiling a new update should be as easy as replacing the "mednafen-0.9.29-wip.tar.bz2" with an updated source code file from the dev forum. Then double click the command file and wait for it to finish the compile. After that, it's just a matter of packing everything up in a zip.
Most of the releases lately have been bug fixes, changes to the PSX emulation and networking improvements. The updates usually come every few weeks or months. I haven't experienced any crashing or game breaking bugs with these WIP updates and the next non-WIP release could be a long ways away. I'm not saying that I want you to talk about Mednafen every time it gets an update, but it has been making big strides in PSX emulation and network connectivity. A mention in the roundup every once in a while and a spot in the emulators section would be nice.
Thanks for including Mednafen in your news roundup. I just want to get the word out.
