Okay, so assuming we're talking about an ARM emulating a 6502, which is something that has been done and I've done myself, then nothing prevents us from emulating the 65C816, and if we can do that then we can emulate the 65832, or create a true 32-bit version of the 65C816. This is what I'm thinking to do with my little Raspberry Pi project, I'm using my Raspberry Pi as an accelerator ( ie. a turbo version of the Transwarp) hence all my questions here about bus timings, but I'd also like to make it so you can choose the chip to emulate and add a 32-bit mode either by emulating the 65832 or creating a 32-bit version of the 65C816.
