I really like this app, I used to use rominator to trim in batches but this is way simpler to use, anyway for some reason it appends a second ".nds" to rom files, so it i trim for a example "game.nds" the output will be "game.nds.nds", that's a problem because of my existing saves so I have to take that extra ".nds" out of em... I did a litle bat file that does that for me but still if you could look into it I would most appreciate it.
edit: ops.. sorry man didn't see the new version, good to see that's taken care of
