[Coco] The Apple II source code for Prince Of Persia- found after 22 years

[Frank Swygert]

That's the case with most ports from another system. I started what I 
thought was going to be a port from a GW-BASIC program to the CoCo3 once 
(the genealogy program I "wrote"). I had to re-write 90% of the code. I 
did give the original author credit, but instead of "ported from" I used 
"based on" in the credits. I used concepts and basic framework, but 
little actual code. It was a PD program, by the way. I did the same with 
a checkbook program, but was able to use a bit more of the original 
code... only rewrote 75-80% of that one. Those were all text based 
programs, I can't imagine rewriting a GRAPHICS based program!

My gut feeling is that, given the architectural differences between the
Apple II and the Coco, such as graphics, memory map, sound etc, the way to
go would be to write a Coco port from scratch using the source as a guide.
