I agree, that would be a great program

Wesmic said that there was once a program that uncorrupts replays to make them playable in a new patch, yet it was never recreated for the patch following it. Someone should recreate or make a program that does it, it would be easier to use than bwchart and installing an old patch
A program such as this would solve many problems Melee'ers have with Blizzard patching so much.
What wesmic said actually was a progarm that "fixes" the corrupt replay to be able to play with a new patch.
Though a suggestion like your's would also be good, like a program like SC that runs a replay you watch, but not the actual game.
