For a quick example of what I'm talking about:
I made
this quick movie file because it shows a quick use of L and R to do tricks. I then loaded the vbm in the TAS Editor, which recognized it as a GB file (not GBA). Without changing anything from the original, I saved the TAS Editor's version of the vbm as
this file. You'll see that the tricks are not pulled off, obviously.
So uh, have a field day with it. If other people aren't having this problem, I guess it's an error on my part. However, I don't see why the editor would assume that my vbms are GB oriented, rather than what VBA deems it. Maybe a quick fix would be to have the editor assume that all vbm files can use the GBA's inputs(A B L R < > /\ \/ S s). That way, GBA is covered, and GB/GBC simply won't be affected by L R inputs. Just a thought.
