I started using the N++ one and it's awesome . I was able to fix this easily, but the current version doesn't highlight SP as a register, and doesn't highlight bjump the same as bcall (in fact, it doesn't color it in at all).
Yeah, I haven't updated that one in a long, long time. First version of all three of them left out SP, SLIA, B_?JUMP, binary notation, and a bunch of other stuff.
