I tried searching for this and couldn't find anything.
There are several cases where the revision appears to be incorrectly placed in the game title. For example:
Legend of Zelda Rev PRG0, The (1987-07)(Nintendo)(US)[b2]
I expected it to be:
Legend of Zelda, The Rev PRG0 (1987-07)(Nintendo)(US)[b2]
Am I mistaken with the naming convention or are these errors? If so, I can provide a list of the ones I found in all files.
