I'm speculating that the Bee bytes can do damage more than once, the health kit bytes are (probably) obviously heal your animatronics. The grim reaper (or whatever) bytes can probably allow animatronics to do heal on hit. The flying robot bytes can probably do splash damage (deal damage to every enemy), the token bytes are... I dunno. The bombs might be the same as the robot bytes, but they probably do more damage and might kill themselves. Then the eye bytes. I dunno what the frick those do. But we might as well find out.
I know why you can only select four bytes. Four bytes, one for each animatronic.
