Emu's answer to that myth:

We got the Ultimate Filmation games (Knight Lore, Alien 8, Pentagram) up to the Spectrum speed level on the C64. It took a bit of work because we converted the Z80 code into 6502 first. The problem with that approach is what works well on the Z80 doesn’t work well on the 6502 and vice versa. So a lot of code had to be re-written and optimised for the 6502. That’s fine if you have the time to spend on the optimisation phase.
I’m sure a ground up 6502 conversion would have been more optimal (especially if hardware sprites were used) but it would have taken longer and been less accurate.
