Open the program HxD
drag the save into the program.
Go to the last line of data (you'll notice the left being 00020000)
Delete the last row
Save.

This only applies to saves of that size. make sure you keep an unedited backup of the file somewhere else before you attempt to do anything you're not sure of.
