It's a thing here, we greet newcomers with peanuts

Guess what I just finished building O.o

Happy Birthday!
Have a birthday muffin:

That's some awesome drawing

I have several things:
1) Can you replace all the lower case letters with uppercase ones in the commented version? they take up a lot of MEM. (lowercase letters are two bytes right?)

I recommend putting the uncommented version on your calculator, you can open the commented one in one of the many online editors there are

2)If i don't know weather my user is using a ti83 or a ti84 then how do i compile? Should i just fallback upon the ti83 method? Is there a way for greylib, when run, to automatically choose the correct setting?

You do that with
1->^^oGS83
before including the lib via prgmGRAYLIB
The library will handle all the differences for you!

3) Can i strip out every thing i don't need to just leave the timer/inturupt stuff.

That happens automatically while compiling!

4)Is there any advantage of using the Crystal timer (84 method) verses just using interrupts?

The gray will look way better if you use the crystal timers as the frequency can be adjusted way better. Again, graylib handles all that

5)Doest using the Crystal timer (84 method) mess with the cpu speed?

Well, any interrupt messes with the CPU speed, as while the interrupt is running the normal code can't run. So there's no way around that when using gray.

AND LAST BUT NOT LEAST:
Your library can render text with all shades of back/fore ground. And yet when i asked about the ti84 and the location of the sprite sheets, you "At least, I hope that information's correct. I haven't tried any of this, but this would be my best guess as to doing it correctly." (https://www.omnimaga.org/general-calculator-help/where-does-ti-(84)-os-store-the-sprite-sheets-for-chars/msg399940/#msg399940). So how exactly do you render text? ("performs magic" is not a good enoufe explanation for me    )

sorry don't have an answer on that one

For those of you who didn't like the grayscale that reuben2 had compared to reuben1......reuben3 has the exact same grayscale awesomeness with crystal timers that reuben1 has! I did this with using the crystal timers, and, as the 83+ doesn't have them, i fall back to the hardware timers. It actually uses just the same save file as GrayLib, to encourage people to make grayscale settings per-calculator!

No, that is not the case, because the calculator screen has a certain refresh rate. The goal is to hit that refresh rate as good as possible, else you are either to fast or to slow, thus the gray because distorted.
