Hi fellow developers,

Just wondering if any of you had experienced different behaviour on your homebrew efforts under MAME vs real hardware?

At this early stage of my development I'm not overly concerned, but I am a little surprised that I do see a number of differences. I won't bore you with details but I do, for example, suspect VRAM accesses are (significantly?) faster under MAME than real hardware?!?

I also see a few other minor behavioural differences, but I can't rule out the possibility that my code isn't following the rules. Regardless, I'd expect an accurate emulator to behave the same way.

Interested to know if you have similar observations?

Regards,
Mark
