A quick save feature that can be activated by pressing select. I really don't care what method is used to make is happen, but I would prefer a 1.1 update .cia file (so using either romfs or code.bin, not sure which it would require). I don't think there's much I can do, as I'm pretty new to this stuff, but i can provide all the necessary tools, as well as a no-lines 1.1 update .cia for either version.
