9/1/2004: If you think Radikal Bikers is a cool game and wanted to see what it was like running full speed, here is a little standalone emu I whipped up. It was just a fun side project to learn Direct3D 8 and to see if some static recompilation techniques I've been thinking about would work. It's not super-polished, but it works well enough to play a few games. You need at least 2GHz and a 64MB video card to get full speed.
