Its extremely important that the archive matches the folder name. Because when we use [RomFile] GX uses whats on the left hand side of the pipe symbol...which should be: Aero Fighters 2 [NGCD-075, NGCD-075E].zip When we use [Rom] GX uses all but the file extension on the left hand side of the pipe symbol...which should be: Aero Fighters 2 [NGCD-075, NGCD-075E] So when we have the code: [Rom]\[RomFile] Which GX reads as: Aero Fighters 2 [NGCD-075, NGCD-075E]\Aero Fighters 2 [NGCD-075, NGCD-075E].zip Which is out game folder and game archive...but we need the path there to the game folder so we use [RomPath] in our code: [RomPath]\[Rom]\[RomFile] Which probably translates into something like: C:\Roms\Neo-Geo CD\Aero Fighters 2 [NGCD-075, NGCD-075E]\Aero Fighters 2 [NGCD-075, NGCD-075E].zip
