I had only ISO images, so I had to re-rip a game in cuesheet format in order to successfully add it to my OpenEmu game library. DeSmuMe is the only DS emulator that works for both.
However, if you want is to use Windows as well as Mac operating system at the same time, Windows emulator for Mac is the solution for that.
Over the weekend I tried out the experimental version’s Playstation 1 emulation.
In my last post about OpenEmu I mentioned the “experimental” build that adds support for many more systems than the official release of the program.
