Readme instructions in: https://github.com/xtagnado/Xtag-Autosplitters It start only you confirm the Mushroom Cup, Mario Circuit 1. Then splits every finish line. I made it from ALTTP's autosplitter, but i'm not an developer, but i've tested it many runs in many emulators (see the emulators compatibility in readme) hope you use it, run with it and be helped about it.
