Your calculator is an 84+CSE, not an 84+CE, right...?
If not, I'm afraid to say you've come all this way for nothing, as this emulator is for the 84+CSE only. Blame TI for the very confusingly similar model names.
On the plus side, the 84+CE has significantly more powerful hardware than the 84+CSE (still paltry by modern mobile device standards) and it has some pretty decent games already. No Game Boy emulator (yet?), but you may want to check out the list on
ticalc.org.
