C64 VICE Speed Question.

[JohnnyRockets]

Hi all,

 

If I write a program and run it in the VICE emulator and it runs at an acceptable speed, what can I expect speed-wise from the "real" C64?

 

Are there any comparisons out there? I know that this could vary wildly from program to program...

 

 

Thanks,

VICE is very close to the real hardware and whatever speed it shows code running will be the same as a real C64 as long as both emulated and real machine are using the same video standard.

 

The only thing to watch out for is that some of the really quirky behaviour of registers like the smooth scrolls are just a tiny bit off in specific situations so there might be the odd graphical flicker here and there on real that the emulation doesn't show; the only one i remember having like that was when trying to split the horizontal smooth scroll between a play area and status bar, the emulators (VICE and CCS64) both reckoned it was a clean split but my C64C said there was a slight glitch.

Great to hear, thanks for that info TMR!

 

Same speed, but check things out on the real hardware.

 

Got it!
