Just press D on the course select to switch between Scotland and the other four courses. I tried to use the CD version as the base initially but it was far too messy. Instead I went for the ROM version and only patched in the new course as an additional. And the score saving works.
So that explains why I've been a bit quite since January.
The biggest change is this version contains both JP and US versions of the game. There are considerable differences between them, most notably the US has 2 player mode and the JP version will kick your ass :D
I'm still around, I've just been very busy patching some golf game to have 5 courses.
I wouldn't bother asking any more questions though as I can't answer them
