I made an autosplitter for th15, so everyone can use it if they want https://github.com/SUDALV92/Touhou15ASL maybe a good idea to put it in Resources

You can use autosplitter, if you play in Steam version of the game.

I think any extra stuff (include crystals) not include in "100%". "100%" category name its just a name, this is not math 100%, so we can call 100% + crystals + extra = "all stuff" or "120%", it is not about real math.

If you play solo mode, you can set compatibility with Windows 8 and use "Window capture", but in co-op mode it will cause lags.
