I think i may be able to help with some of the problems people are experiencing with the newer calculators. As i managed to get a few roms to work ok (t2 the arcade game and kirbys dream land) but most just crash usually st the start menu or a few after nintendo logo (wario blast). I think it may have something possibly to do with the graphics driver as newer ti 84 plus se have different software/hardware to the older ones which can cause problems with a few games.   

PLEASE NOTE
a couple of people have posted saying that the game just crashes after the nintendo logo, full stop. that happened to me with all the roms i tried until i simply just zoomed in with the 5 button and the games worked (to some extent) after that.

Also the program that makes games seems to have trouble with any sort of pokemon, but the many versions of pokemon ive tried do happen to me over 1MB so that could be the issue

P.S
is there any chance you can merge this into a mirageos/ion program? to make it possible to run it off usb flash drives ?
