As far as I know, it's an actual port of the NES code (both the C64 and NES use 65xx processors), rather than a more traditional conversion. This means it behaves exactly like the original, but has slowdown where the NES was doing more in a frame than the C64 could handle.

I gave it a very quick burst in an emulator, but I'm going to try it on my actual C64 at some stage, so I'll see how it plays then (just been a bit busy this weekend!).
Going back to the port, each 8 bit machine works in a very specific way. For example, the NES can display more sprites than the C64, but they're much smaller. Something that's relatively simple on a NES could be quite tricky on a C64, and vice versa. With this port, almost everything to do with video/audio output would still need to be re-written as you're using low level code that depends very much on the architecture of the machine. Because SMB was written for the NES, it takes advantage of the NES hardware. If it had been a C64 game, there would probably be a few small differences that would take advantage of the C64's hardware.
I think this port was all about accuracy, but I'm sure a version of SMB that is very similar to the NES version could be made and it would run at 50fps, but there might be a few small changes to account for the differences between the NES and the C64. Like Leon said, Giana Sisters is a good proof of concept for this. It's definitely an inferior game, but that's probably down to the designer more than the hardware. Of course there may yet be further optimisations to this version, I'm not sure where the project stands.
Someone did actually release another version of SMB which takes a different approach to the graphics, although it's a very early demo that I believe didn't progress any further https://csdb.dk/release/?id=114516Last edited by ZipZap; 20-04-2019, 11:13.

I read somewhere that there are still copies of the re-release of Gleylancer in Tokyo stores. I’m wondering if any kind folk here who live in the Land of the Rising Sun might be able to pick me up a copy if you see one in the wild? I’m willing to pay above cost (within reason) for the trouble.

Columbus Circle are doing a run of Ultracore, pre-orders are up on amazon.jp
Would a kind soul with an account kindly assist me in placing an order? Happy to PayPal or wire funds over. I don’t want to miss out like I did with the Gleylancer re-print.
Incidentally if anyone has a Gleylancer re-print they don’t want then I’d be happy to take it off your hands for a reasonable price
