+;* Use for LEARNING practises ONLY!
+; Don't ever release altered code w/o permission!
+;* Code was originally by Scabby (Matthew Shepcar),
+; a few lines by Jonah Cohen,
+; and everything else by me - Shiar (Mischa Poslawsky).
+;* Although I've commented quite some stuff, I can't guarantee
+; everybody will understand it. This is probably not the best source
+; to learn z80 from. w00t the Shyer Way (tm).
+;* Don't scroll down if you get scared easily.
