I am working under the assumption that RAM writes work the same if the are executing in the $f000-$f0ff range as any other location. I may be incorrect in this assumption. > The only way it could be a valid write of $3F to $f7b is if the SC was able to distinguish between opcodes and operands. And I have no idea how they would do that in a cartridge.
