This is a fork of FIX94's triforce-nand-iso-extract that extracts an ISO out of MAME's Triforce NAND files.
Grab the TriNandIsoExtract.exe and place it into a new folder.
Copy the .bin files of your romset into that folder as well.
Run TriNandIsoExtract, choose your game and wait for it to create a OUT.BIN.
Rename that OUT.BIN to for example game.iso, it is now ready to play.
NOTE: MAME currently has bad dumps for Mario Kart Arcade GP, so this app currently only works with F-Zero AX Monster Ride. The original version of this app requires an ISO of the American version of Mario Kart Arcade GP 2 for this reason.
