I'm sorry if this question was already asked and answered, but are Ti-83+/84+ crystal timers emulated correctly on the Nspire?

No they are not

That's why some programs like thepenguin77's Chess don't work on the Nspire 84+ Keypad.

On a related note, here's an easy way to check for Nspire:

	xor	a
	ld	r, a
	ld	a, r
	cp	2
	jr	nz, Nspire

And make sure interrupts are disabled first, of course.

Ah yes, that was actually the line right before that. I just didn't notice it.

Crystal timers do work on the 84+/SE right?

And the 83+SE. Basically, all of them except the plain old TI-83+.
