So I managed to solve this, but I'm not entirely sure how. I fixed the under-voltage issue with a better power supply. Entered a game and had the same issue. Remapped after exit, then decided to see if it would do it again with other emulators, and like magic, I could never get the issue to reproduce even after a reboot. So.... I have no idea. My guess is it was related to the undervoltage and the board wasn't getting enough power causing a small memory dump when exiting the emulator.
