just for anyone who is concerned, I tried using the latest nightly cia build of gpsp, and so far it's been the best in terms of it not crashing. I'm impressed, played Mother 3 for about an hour or so without any issues. Only crash that I can report was due to exiting retroarch without pausing the game first, it crashed upon reloading the app, however pausing retroarch and then proceeding to quit seems to be fine. Saving seems to be working properly as well. further testing is required, hopefully it doesn't randomly crash still.
