Well, it´s been a long, hard road since we started working on DeSmuME back in April. And now you too can enjoy the fruits of our labor.

So what´s new? The main things that were done were rewrites to the code(it´s now 100% C code, compiles and runs on 64-bit compilers, and is almost big endian safe), FAT/CompactFlash emulation, framebuffer emulation, sound emulation, backup memory emulation, and save states.
Anyways, the source, windows binary, and linux binary are all available on the downloads page. Merry Christmas
