game not found

It is not listed here, gb64 or Google but why would this game not be in c64 when almost all the early 80s arcade games were?

I am looking for Mappy.

It was never ported to the C64. Maybe it is a job for some game devs.

it was ported to the 2600, Colecovision, NES & Spectrum. All a 6502 cpu. So it should have been an easy port.

Colecovision and Spectrum don't use a 6502 though :)

My fault. Thought I read somewhere they did. It is Zilog Z80.

But still those systems had lower specs than the c64. Especially in the sound & graphics.

Spectrum Zilog processor frequency is at 3.5 MHz, thats 3.55 times faster than 6502 processor frequency of PAL C64. As far I'm concerned it's a superior spec. You can do magic with that, even with the limitations of hires graphic mode of ZX Spectrum.

its apple and oranges though, since a z80 needs about 3 times as much cycles to do the same thing as a 6502. z80 wins when there is relatively few bytes to move, and relatively many 16 bit calculations (which is why its often better with those bitmap based vector games) - but that has little to do with the faster clock.
