Yaay! I just loaded up my calc with epic fail pics.
Why is the keypress detection slow?

The controls aren't very smooth since the keypress delay method I use is terrible so you may have to hold a key down for a while for it to register.

I wasn't clear, I really meant why is this keypress method used?

Because I haven't figured out an intelligent way to do it, so I just refresh the screen 20 times each iteration of the loop.

Doublepost is bad, I know, but here's a minor update. It now only refreshes 3x instead of 20.
Also, you now click at the file selection screen, instead of pressing RETURN.

It isn't as bad if it's made within the forum rules ;) (which is currently the case, since it has been more than one hour for a project update :P)

I'll have to give this a try again at one point. Last time I didn't get it to work, but I think I started to figure out

A bugfix update: the program now calls free() appropriately at the end of main() to free the malloc'd blocks of memory. This should prevent some random crashes I've been getting.
Also, attached some screenies. We all love screenies, right? :)

I think that dithering was from the screenshot program-it is dithered in the border of the emulator.

Yeah, I think that was caused by Windows Snipping Tool.  It is like that on all screenshots I take with it.
