 We'll rickroll you instead! Edit: Also, shouldn't this be in randomness?

Looks cool!  Also, technical notice: either SDCC or Z88DK (I'm not sure which) does perform optimizations on the generated assembly code, but, as stated, the optimized assembly code is still far from good. Good luck on doing better!

I've heard of this before. Fun stuff  Also, if you want to use it but are too lazy/cowardly to use the direct source code, here's a (dis)assembler: http://yagni.com/whitespace/index.html

Hm... I can give a general ASM tip to help with the messed up pixels problem. (Unless I have misunderstood, of course. Credit for this method, AFAIK, goes to calc84maniac)
xor b
and c
xor bIt effectively selects bits from b to put in a.
A set bit in c corresponds to leaving the original corresponding bit in a, and a reset bit corresponds to overwriting that bit in a with b.
For example, if a=%10100110, b=%01101011, and c=%11001101, then the result would be %10100110 in a, with bits 0, 2, 3, 6, and 7 coming from a and bits 1, 4, and 5 coming from b.

Given that normal circle drawing looks a lot like drawing a parametric circle in terms of speed, an Arc( command would probably be as fast as drawing an arc with parametric graphs. Just my thoughts, though. Someone will have to verify whether the speeds are the same

14 minutes! I'll be there again.

How much wear on the flash ROM do you think saving RAM to flash will have?
If this becomes possible but would require extra sectors, I'd still like an option as to whether RAM is backed up  I could see it as useful. though. * calcdude gives his standard "keep up the good work!" message and wishes pokemon could work

Which? MS-UNO is a joke, first of all. (DOS, which actually stands for Disk Operating System, can be taken as the Spanish word for two. The Spanish word for one is UNO, hence MS-UNO.) Hiroshima and Chernobyl were nuclear incidents, and I guess that's somehow being linked to the stereotypical horridness of Windows 95

You can, but you can't use Get_CSC. The [ON] key is special, and there is no skOn.
The code to test if the [ON] key is pressed is this:
in a,($04)
bit 3,a
jr z,ON_pressed

I don't mind about simultaneity for normal purposes, but it does annoy me that there's no Arc( command. (With a theoretical syntax of Arc(X,Y,Radius,Start,Stop), where Start and Stop are the angles where the arc, well, starts and stops. )

If you use your own interrupt or turn them off, then the MirageOS interrupt will not work. If they're getting turned off and you're doing neither of these, it's because some instructions turn off interrupts. They can be re-enabled with FnOn after those instructions.
* calcdude asks Quigibo to document how instructions affect interrupts. (More specifically which ones turn them on/off)

TI-84+SE, actually. Not too bad an amount.

You can't draw arcs that way, though, nor can you draw equations simultaneously

Mine is a drawing of a happy face using parametric equations. Once any of my projects takes on a screenshot or a logo, I'll probably use that.
