For those who don't know, there's a really annoying bug in GFW that can render your replays unwatchable (the game crashes when trying to play them). Here's a detailed explanation, under "Wrong Route Glitch":
https://en.touhouwiki.net/wiki/Great_Fairy_Wars/Gameplay#GlitchesI was severely annoyed by this, since it happened on my first 1cc clear, and I really wanted to preserve the replay. So I set out to find a way to fix it. After several weeks, I ended up coding a tool myself to fulfill this purpose. I'm now releasing it to the community for anyone that may also want to recover their bugged GFW replays!
Here's the tool, you can download the EXE from the releases section:
