Soll ich jetzt in deutsch antworten? Ich glaube ich bleibe bei Englisch,
damit der Rest der Gruppe mich verstehen und notfalls verbessern kann. :-)


The question was, if a CMP $f123 would cause a write, if I put 100 NOPs
after the CMP $F000,X.

I don't have a debugger for the Supercharger, but I think, if my theory
is correct, this constellation would have the 2nd or 3rd NOP cause the write
to finish and therefore be overwritten by the value to write.
