Sonic Robo-Blast 2, a 3D Sonic fangame based on the DooM Legacy code base, has been ported to the Dreamcast. However, since this is a beta, please note there are bugs:

– Gamepad support is still very problematic. While not required, it is reccomended you use a Keyboard.

– With using SDL, the framerate isn’t very good. Normally, SRB2 runs locked at a max of 30fps. Here, framerate depends on the size of the room, with an average of 10fps. (The coders mentioned they are going to abandon SDL for the Dreamcast port in the future, which should increase speed in future versions)

– It seems to crash after playing a few maps.

– There’s no sound yet.
