While TASing in Bizhawk 2.11's DosBox-X core in TAStudio, I tried copying and paste-inserting several lines of input to the end of the movie, then Undo.
This causes an unhandled exception, but Bizhawk will continue working after this.
Something about System.OverflowException, and array dimensions being exceeded.
EDIT 1:
In Bizhawk 2.11, also while TASing in DOSBox-X, I tried copying input in TAStudio from a movie that had mouse input to a movie that had mouse disabled, but it just made all keys active.
EDIT 2:
In Bizhawk DOSBox-X, while TASing in TAStudio, if I press Left mouse button at the end of my run and save that to bk2 and play back the movie, it doesn't register the left mouse button press, even if I put 1 additional idle frame before exporting to bk2.
EDIT 3:
When TASing DOS, please make it possible to clear mouse coordinate/speed input in TAStudio. It seems once there are values, they can't be removed...
