I beg to differ with respect to the timers:

The TI-84 uses the timers for its own purposes, leaving only timer 1 free.

Though how it uses them, I have no clue
(The normal OS, that is)

I don't think so, as the 83+SE had crystal timers and didn't have a clock.

Of course, if it weren't for powering down, clocks could be made for the 83+ using interrupts.

WHERE BE MAH STARFOX APP?

 @DJ: No no no. Like I've said before, I float around from thing to thing. Lately I haven't been doing much programming because school's given me quite a bit of homework, plus I've just been doing other things. I'll definitely get back on programming eventually. I'll just be bored of it for a while.

However, I do see slight problems with this game. While it is really cool with the 3d graphics and such, I'm not really sure it has much playing value. This game doesn't seem to me like one of those ones where it's like, "Dude you gotta try this!", it just seems more like a cool idea. I feel like once the initial shock of 3d graphics on a calculator subsides, the game doesn't have much to offer as far as gameplay. Which is also part of the reason that coding it is boring. Before, from one update to the next, I would be totally shocked at how awesome it looked. Now, most of the updating is just adding more levels and making them longer, which at least for me, is really boring.

I'm not sure exactly what the fate of this project is. Like I said, I feel like I've pretty much taken this far as what would be useful. But only time will tell.

Having someone make the levels is a possibility, although I'm not really sure anyone would want to make levels. It's kind of boring. After I get the enemy paths in, it's just typing in a list of shapes, enemies, and coordinates while sometimes defining new shapes.

But when I start programming again, I assume I'll probably start working on my tower defense game again. That or bluetooth, but bluetooth gets frustrating pretty quickly.

But what about all those characters talking to you while you play? That would make it interesting I think

Does it take a lot of processing power to make textured walls?  You've got your engine, so a tank game might be fun, with cities and what not--I woud gladly create the levels for that!  Even more so if the city scape can be rotated 360 degrees left and right
