I'm new to making TASes, and earlier today I had attempted to make my first one to get the feel for it. Here, I was facing against a lvl 3 Yoshi and mid-way through the recording, Dolphin crashed and I had to start back up from a savestate. As a result, the .dtm file would end upon startup and the in-game replay speeds up where the crash happened. What measures can I setup to prevent this in the future?
