in some situations with gc games it may be enough to set the memory card slots to nothing
for wii games you could remove the save from its save folder

Having to remove the save file each and every time I go to watch a replay (In terms of doing recordings) to confirm input is a bit of a nuisance, if a DTM could have a flag which tells Dolphin to simply NOT do a save would be great.

My theory; When the flag is toggled it picks a random (but not existing) foldername and makes it and does all the saving in there but once the recording session ends it removes that folder and it's contents.
