can i use android nostalgia.gbc? he uses practically 100% of the last gambattle from what I saw he doesn't print

Hi, I came by this post by accident but maybe I can provide some information. I did some accuracy testing for Nostalgia.GBC and unfortunately it is not accurate at all, so I wouldn't use it for speedrunning.

You can find the detailed results here: https://www.kleemans.ch/static/gb-emulator-timing/
