An emulator for Spike Chunsoft Pak Files
Supply the vanilla .pak file in the WAD File Emulator wherever it belongs
Then create a new folder in FEmulator/PAK named after the pak file
Then put a named file that is named after it's index (eg 53.tga etc) (file extension is ignored)
Then the file at slot 53 should be replaced with your new one
Now you can edit the pak file without repacking it every 10 seconds!
