Hello,

I believe that DOSBox does cycle-correct CPU emulation. Does this include video RAM timing? And more generally, does anyone know where I can find information about video RAM timing for VGA devices? (I realise that this differed by manufacturer, but I would imagine that there must be some information available.)

Thanks!

Regards,

Michael

Wrong, it does not.

From the inside DOSBox video ram is as fast as cache... like every type of memory.
