Ah, I guess I've mistakenly assumed all the Kenta Cho shmups need OpenGL because rrootage does. Doesn't seem like this depends on it at all. I wonder if any others that have Linux ports don't have that dependency.

<edit>
Seems like they all do, there's at least this version of rrootage's sources for the GP2X modified to run on the GP2X's OpenGL ES hardware though. (with reduced effects compared to original)
