i made a simple grayscale editor where you can define the height and width of your title screen and edit it pixel-by-pixel. when you enter a number in, it has to have two digits. meaning "6" is not a valid input, it should be "06". it's pretty simple right now.. you move a cursor around where [2nd] inverts the pixel on the buffer, and [alpha] inverts the pixel on the backbuffer. mode inverts the buffer, xton inverts the backbuffer, del clears the buffer, stat clears the backbuffer. they literally use drawInv and ClrDraw, so when you invert the buffer, not only will your title screen be inverted, but also the rest of the buffer.
unfortunately, i don't have access to a link cable right now.. so here's the source code, if you feel like typing it in. the source is only 440 bytes, the executable is just over a thousand. here's the source:

ClrDraw
ClrDraw{^r}

{input}^r->C^256-48*10+(C/256-48)->H

Repeat getKey(9)
If getKey->K=54
Pxl-Change(X,Y
End
If K=48
Pxl-Change(X,Y)^r
End
If K=55
DrawInv :End
If K=40
DrawInv ^r:End
If K=56

If K=32

{{Z/L*B+L6+Z}->C/16+Str1}->(Z*2+A}
{C^16+Str1}->{Z*2+1+A}
{{Z/L*B+L3+Z}->C/16+Str1}->(Z*2+(U*2)+A}
{C^16+Str1}->{Z*2+1+(U*2)+A}
End


Nice, I would like to eventually see more development on this, like some tools such as rectangles, flood filling, etc. I'M glad to see more drawing tools for Axe

Maybe he did a typo or there's part of the code that was meant to be something else, idk.

Btw, {^r} is meant to be ^r. No clue about ^r, though, nor {input}.

Ya, I don't know. I mean there are typos in the code (no offence, nemo) like that one and I thought I caught them all. The only one that I see that I'm not sure about is "DispGraphrr" but I'm assuming it's supposed to be DispGraph^r. {input} I figured out, it's just another command that wasn't in the version I had on my calculator, which I fixed. What seems to be happening though is that it isn't repeating or something.

Oh...how did I not realize that

And what about the places where you start with a ( and end with a }?

Edit:
I still can't seem to get it to work

Ya, that's what I assumed.

Not I

Well from what I'm seeing this do it looks like what happens with TI-BASIC when you don't put a End at the end of a loop.
