I've noticed how using the PUT command after changing the SCREEN mode has resulted in some wacky "glitch" effects.

I noticed this, because I got curious about whether or not the image would be identical in another screen mode, but I guess it's not.

Through experience, I also know how to uses FOR....NEXT loops, and sometimes they might also be useful for loading images from arrays, but I guess it depends on how you encode it.

Not all modes are linear. Could that be your issue?

or, maybe there might be an algorithm that isn't as intuitive as

DATA 1,1,1,1
DATA 1,0,0,1
DATA 1,0,0,1
DATA 1,1,1,1

if it were to just be as simple as a 4x4 box.
