I think the Commodore 64 Ultimate can do even more. With 64Mhz turbo enabled, 16 MB REU used, etc. It's untapped still, in my opinion. Only thing that can't really be increased is the number of colors, but it is FPGA, so it it's possible with firmware updates. VIC-III was a chip that can display 4096 colors, a chip that was actually designed and produced in limited numbers for the Commodore C65, a machine that made it out to various developers before… See More
being cancelled. I don't think the Commodore 64 Ulimate needs to be fully C65 compatible, as there isn't enough C65 software out there to justify that. But adding some graphics modes it had, would be nice. 64Mhz turbo of the Commodore 64 Ultimate outperforms that C65's 3.54Mhz by quite a bit. In fact it even outperforms the SuperCPU's 20Mhz turbo mode, even though it's 16-bit. Possibly a few things the SuperCPU can do faster with moving memory block around. However, the Commodore 64 Ultimate includes the REC (blitter-like) chip in it's internal REU (RAM Expansion Unit) that can more than make up for the missing 16-bit op-codes.
I wonder why certain SuperCPU games haven't been converted yet. Or even better SuperCPU added to the FPGA as well. But, again, there's untapped potential, in my opinion. But then again, we have modern PCs and consoles. I suppose if we take away some of those restrictions, such as 16 colors, it wouldn't be something special anymore.
