MonkeyVGA copy protection bypass

Description

I finally bought a second-hand copy of the "Classic Adventures" collection which, among other things, includes MonkeyVGA. Unfortunately it doesn't include the code wheel to get past the copy protection screen. Apparently LucasArts's own interpreter skips it completely, but I don't know how to do that.

Instead, I made a change similar to the MI2 copy protection bypass hack, based on the assumption that this is the part of script 152 that checks for the correct answer:

[01C6] (88) if (Var[266] != Var[179]) { [01CD] (14) print(255,[Text(" ")]); [01D2] (14)
print(255,[Center(),Color(Local[9]),Text("^255^7&^0")]); [01DE] (AE) WaitForMessage() [01E0] (87) setState(Var[299],0) [01E4] (87) setState(Var[300],0) [01E8] (46) Local[5]++; [01EB] (18) goto 0093; [01EE] (**) }

It works for me, at least.
