yabGBE stands for "Yet another bad gameboy emulator" and it already
perfectly encapsulates what this is. This emulator is unfinished, missing a lot of features and the few features that are implemented seem to be of questionable quality.
This is my first ever emulator programming project I tackled all by myself, without looking at explicit tutorials. I only used hardware docs and the gbdev wiki to get all my informations and knowledge.
Anyways, here is my emulator emulating tetris

Hell yeah do you see that?? I visualize all the frigging memory, ain't
that something cool? I think it is, at least, you get to see ALL the changes in memory and registers every single frame.
