Where's a fast version of VGMTrans?

I got VGMTrans so I could listen to unused tracks in Pokemon Mystery Dungeon. But when I loaded it, it was slow as heck! Sure it was fast opening, but when I clicked the "Open" menu, it didn't come up at all! I could have been EIGHTY before it loaded, and by that point I wouldn't be interested in it anymore. So where is a fast version of it?

Get a faster computer, there is no 'faster' version.Or find an alternative program.

Unfortunately, I don't think there is an alternative program.
