Google is a supercreepy gigantic information logging information collector. They are collecting so much information about everyone that it's extremely scary. They know everyone's secrets.

Crazy Z80 optimization trick!

Bregalad on the Nesdev forums just informed me of a trick for optimizing if-then-else type blocks, where the "else" area consists of a 2-byte instruction. So you normally have an if-else-endif block like this: jr nz,else ;the IF ;some code jr endif else: ;some code endif: But here's a craz...
