Reicast is an alpha release emulator for the Sega Dreamcast. It was released today to the Google Play Store. I can't believe how bad ass it is for being an early alpha. You can check it out on the Play Store by clicking here. The projects main website can be accessed by clicking here. I gotta say, i freaking love the dreamcast and a portable emulator is really awesome.
Below are quite a few screen shots for your consumption.
