A word to the wise: I don't know how you want to go about your project but emulating any of those old processors is a fairly trivial matter. The surrounding hardware is a completely different ball game. In many cases it doesn't even make sense to emulate the video or audio circuitry because you are targeting different devices.

What you can probably do is to take the ROM entry points and treat them as black boxes and reimplement them to fit your system. For C64, I've seen a list of Commodore 64 standard KERNAL functions[^] that can serve as a starting point. There seems to be also a listing of the C64 Kernal that can serve as an inspiration for your implementations.

From a legal point of view, you would be implementing an API. I know that Oracle takes the view that this is an IP infringement but there are many lawyers who disagree with them. At any rate, you are probably a fish too small to fry for any of these big companies (no disrespect intended Smile | :) ).
