theres a cab. Its still a first beta so you have to follow the directions to launch TFlo3d, but it does work. Unfortunately it takes about 20mb of ROM space which the Diamond doesnt have a lot of (prob not overwriting old files but making new ones).
Either way one you get it started up its great and the fastest Manilla version ive seen
