This one may seem a bit random, and yeah it kinda is but it seemed interesting and worked out easier than i expected so i thought i'd share.
add cheat codes just like the old school games, or combo attack inputs for fighting games, etc etc there are a few different ways i could see this being used.
we'll start off with keyboard inputs and then i'll show at the end how to set up gamepad inputs also if that's more your thing.
