I would really like to see Super Mario added to Ion. Also, I think that when most people ask for a port, they just want a game simmilar to it. I know that there are millions of docs out there for every calc, but usually they are in lessions and were never completed, or are cryptic. The TI-83 is TI's most popular calculator, no questions asked. It has been adopted by hundreds of schools across the country as an updgrade to the TI-82, and it will not soon be replaced by another calculator.
ASM documentation exists.
If you'd looked for it, you would have found it. As I said, I know there are assembly documents out there, but every one I have read is missing something. Game programming isnt just a matter of putting pixels on the screen and processing keys pressed. I linked to the BEST ASM tutorial that currently exists. I can program in asm.
