Decompile them all and recover your game files or mod your fan-game. uTinyRipper is free for download from https://sourceforge.net/projects/utin... - for some reason the releases on the GitHub page stopped? If you can't export a game, 1. download the latest version. If that doesn't help 2. report the issue on utinyripper's github issues page.
