+
+; * Game README is wormy.txt
+; * Use for LEARNING practises ONLY!
+; * Don't _ever_ release altered code w/o permission!
+; * Give me credits when you use any of this stuff
+; * I'm not responsible for any damage this might cause, yada yada...
+; * Although I've commented & labeled quite some stuff, due to
+; crazy optimizations and weird coding, it may be harder to
+; understand than the average blob of code. This is probably _not_
+; the best source to learn z80 from. w00t the Shyer Way (tm).
+; * Email me. If you've got suggestions|patches|questions: tell me.
+; * Don't scroll down if you get scared easily.
