This seems to be reasonably safe, but I thought I might add some facts: The file you're editing is *:System:ExpressLoad; the two bytes to be nop'd are at block $15, offset $003B-003C; you should see AF 25 C0 00 just before the AND, CMP, BNE sequence as opposed to AD 25 C0. > [Raising My Hand] > Mr. Software Engineering, can we please get rid of that silly "Welcome to > Apple //GS"? That phrase doesn't even make semantic sense in english. It actually says "Welcome to the IIgs" which is a bit less cumbersome than what you were thinking it said.
