nspire-z80: open source ti-84 emulator for the nspire cx

This emulator is not fully functional, but it can boot up TI-OS, so it's fairly complete. It seems to freeze if it's idle for long enough that it should turn off, so don't use it for anything critical. However, it does work, so I'm publishing it now. I hope to keep working on it and add the missing features.
Download
Source code
To use, launch it once to register the file association, then launch a rom file with the extension "8rom".
New in version 0.10: Fixed save states, Hardware W+ support, on button, offscreen area emulated

Hey that's pretty awesome!
I don't really keep up with the nspire stuff but that's nice to see a working Z80 emulator. You've even got it to a point where it's booting TI-OS. Great work!

Great job! I think this is the first z80 emu for the Nspire that actually runs TI-OS, aside from jacobly's that he never finished. How long did it take to make, and did you start from scratch?

I worked on it some back in May and June of last year, and I finished it in the last week or two. I used an existing z80 core (DrZ80), but all the IO code is mine. The Z80 core is written in assembly, and the IO code is written in C with some assembly components for speed.

This sadly doesn't work on ndless 4.5 rev. AB, the screen just flickers and shows a square, or maybe I have to turn the emulator on?

Mini necropost, sorry :c
Anyways, it looks really cool, would you think that it is going to work on Nspire clickpad (black and white) or it will just instantly crash or something like that ?
