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. -- John.
