the .CO file i'm thinking about isn't part of the main rom, it was loaded into 
the ram memory.  but in any case it still needs to be disassembled? in order to 
have the calls adjusted for the program being accessed from space in the oprom 
area? is that it?

The BASIC rom runs from the same address space as the optrom. So any calls to 
the main ROM have to be specially constructed "far" calls. 
You would need to convert those calls. Also you would need to relocate the code 
to run from different addresses. Probably some other stuff to deal with. 
But first step would be disassembling it.

are there complex changes that need to be made to a working .CO program in 
order for it to be "transplanted" to an option ROM? what i'm wondering is if i 
can take the address range that contains a .CO program, copy the program and 
then just burn it into an EPROM. are there changes that have to be made to the 
program, like jumps or something?
