Holy cow O_O
qazz42, it's a C# .NET library.
As for screenshits, it will do still and gif.
As for grayscale, I will be studying a TI-83+ screen, and tracking how long it takes a pixel to go from black to white, and the rate at which it does, and base it off of that.
Right now, it only supports the TI z80 processor in general, I haven't added enough to make it specific to a model. I'll be doing the TI-83+ first, then the TI-84+.
