When i said speed, i really meant speed. Pac man moves faster in the C64 version then in the Amiga version. Then if he moves at 12 fps or 100 Fps doesn't really matter.
I guess you are not an programmer? There are two different speeds to handle here. First the framerate. It's 50fps on the Amiga, c64 and my STE version. It's 25 on the ST version, BUT the speed of movement is the same on both ST, STE and Amiga version, just that it isn't as smooth in 25fps compared to 50.
I haven't played the c64 version, but maybe the starting speed of Pacman is higher than the other version. If you get to the later levels, Pacman will go faster and in the final levels he is really fast. Play through all the levels on the Amiga och the STE version and you will see. (The ST version should be the same to)
That's Nintendo Game & Watch. Remove the actual console an keep the screen only, what's left of the Game & Watch experience?
Well I wouldn't try to play a Game & Watch game on an emulator or real life since they are just to primitive and there are better handheld consoles out there
