About 8-9 years ago when people were discussing porting to cf or PPC
I was thinking about the various approaches to porting applications
although my C skills weren't/aren't up to it.

When an M68k GEM app is run, the calls to the GEM/OS features would be
passed directly on. The remaining parts of code would have to be
converted to the appropriate assembler. This might be like the method
you have used.

Then I thought that rather than emulating everytime an old app is run,
why not, convert it once and save the new version of the application
in it's cf or PPC version ?
