Raiden III needs GeForce4 Ti 4800 Videocard setting (seems to be wrong). Resolution forcing works, anti-aliasing works, texture filtering causes two distracting black lines in the middle of the image. I can't get the latest versions available of GOG or Steam to work, however the original asian retail version and the Type X version works fine. Dege says he got a GOG version working too, I'm sort of curious which version that was.
Raiden IV also works fine. Resolution forcing, anti-aliasing and texture filtering all seem to work. Obviously, only the original Type X version works and not the Raiden IV: Overkill re-release as that's OpenGL. Seems to not work on Intel GPUs. Is also much more of a pain to get running than Raiden III.
