@iandaemon thats exactly what i did and didnt catch thank you
According to your diagram, if you swapped where P2 and P3 stood then you can have the same shader on all the games and things would be "smoother" with the video orientation being same for all games.
@dankcushions Ah, that does what I'm looking for, I'll just have to find a way to make it a bit more convenient to use. Thanks! Now I can play Galaxy Wars in its true glory. :)
