Heya and welcome to the forums. Keep us updated about it. Do you have any other tutorials or calculator-related projects in the works? Also TI-Boy CSE is awesome.

Glad to see it finished. Also I usually play in full screen mode on the CSE. It's a bit distorted, but it works pretty well.

Yeah it's actually slower, but after you get used to it, Metroid II wasn't too bad actually and actually fun to play.

And yeah try to be careful to not get your calc (or phone) taken away if you play games/code. I managed to code in class while still doing my work but i had to make sure to not hold my calc like a Game Boy.
