You also have to emulate the GB/GBC's modified z80 core as the secondary processor.
That processor can't be accessed by games running in GBA mode as far as I know. The only way for games to use it is to be a GB/GBC game, and we already have an emu for that.
I heard that you're able to use it as a sound controller, but I'm not entirely sure.Wait, that wouldn't make sense.

I also would like to add that there might be an discontinuity in the cable itself. Make sure to rule that out. OK, thanks. That's what I thought the is the best. And a 84+ would be the right upgrade, but I have to keep my 83+ since this is the only we are allowed to use in exams.
That's strange because only the 84+'s have the Press-to-Test mode. (uhggh)

Yes, it is. It's not impossible, but the people who are willing to make the emulator probably already had the idea anyway. Most of these emulator requests turn into, "this is the hardware you have to emulate, but nobody has done it yet," type topics.

 I think the bar has just been raised.

Woah! NES in color!?

This is really cool! I hope someone could make a full working game out of it!

Customizable interrupt as-in an im 2 interrupt, or changing the timings that the greyscale function gets called from the im 1 interrupt (current)?
Currently, a custom callback is used from the OS's interrupt running from a timer. I think I am missing an interrupting something somewhere as wabbitemu shows no odd timing.
The user should be able to change the amount of times the grayscale routine is being called from your mode 1 interrupt. That will help you with your grayscale flickering.

Greyscale has noticeable pulsing (pulse every .75 seconds, otherwise no flicker... :-? ) As far as grayscale, can you set it to a customizable interrupt?

How does that work?
If you put Goto XX as the FIRST line of the program , the BASIC parser jump to wherever you put Label XX. Once the OS reaches XX, it realizes that it is not BASIC code. The BASIC parser will toss an error saying that it is invalid code. Then, you select the option to goto the error. The only downside to this is that you have to change the first line of the program back in order to have it parsed by Axe.

I have discovered this morning that the TI-84 Plus SE ROM was still included on basic TI-Nspire CX OSes 3.0.1 & 3.0.2, although you have no way to start the emulator to my knowlege up to now...
But the ROM was then removed on the basic TI-Nspire CX OS 3.1.0.
Read more and look at the proofs here:

Oh, I thought you knew that before.

Keep in mind that the newer TI-Z80 models will always reset bits 3 and 5 of the F register, though.
Which Z80s have that change, and are there any other changes made to undocumented opcodes? That's for BIT n,reg8 at least, but my sources say BIT n,(HL/IX/IY) behave differently; BIT n,(IX+d) takes 5 and 3 from (IX+d)>>8 and BIT n,(HL) from .. weird places. Are those sources incorrect?
There are many different models of Z80, so I wouldn't be surprised if there are differences in undocumented flags. Also, I would recommend staying away from IX and IY instructions if you want the programs to work on the Nspire with 84+ keypad.

This is nice. It will be so much easier to sort out the different projects.

I've had the same question. While parsing through the VAT, I've seen some weird stuff.
