Reconsidering the 65816 (W65C816S)

We've seen the videos.
We know it would be like starting over, because the system only works at 8Mhz.

About as much chance as it being personally delivered by Luke Skywalker I think. Timing is apparently an "issue"

Even though the system is designed to be a 65C02 based machine, I designed it such that a 65C816 will work electrically in the board. The KERNAL isn't a fan of the 816, so it would have to be running a different OS, but we wanted to make sure people had the option to do what they wanted with the system.
Stephen Horn:

the '816 either has a conflicting opcode with the 65C02 that the kernel is using, or is expecting some new piece of memory to be mapped in a way that conflicts with what the kernel is doing, and the kernal is crashing or entering an infinite loop before it gets to VERA initialization.

I can't muster even a little nostalgia for [the 65816]
But.
Paul's argument haunts me PROBABLY ONLY because I am not a good assembly language programmer:
With a faster processor, I could write a reasonably performant P-Code interpreter. We could write Robotron (et al) in C, or a kind of Commodore-friendly STOS BASIC.
And keep everything else we've got. (Theoretically)
What Paul is saying is EASE OF USE goes up by an order of magnitude, IF processor capability improves.
