I’m having the same issue. I have texture dumping off and the save states are made in the same session, but it still seems to crash. It happens on SMT IV and FE Fates for me. Haven’t tried other games.
The latest Citra Nightly (1867/1868) appears to have a crashing issue with loading save states, as well as with crashing with certain titles. Please use a previous Nightly build (1866) for now:
Thank you so much for the suggestion! Actually the problem was solved when I switched to Canary with save and load states working properly. Now I’m actually searching for ways on increasing the speed cuz it caps at 100% now despite being increased up to 300%. I turned off limiters in Citra and 3rd party like Nvidia control panel and the speed still ain’t going up from 100%.
