Reduce Prozessorspeed in vm

[wef-offen]

I have some old games (Dos). They are running good on old machines ( 386, 20Mhz). The Gamespeed ist hardcoded an I can't reduce it in the games. Is there any possibility in virtualbox to reduce the vm speed in the preferences of a virtual machine?

as virtualbox doesn't supports dos, you should use dosbox instead, as it is optimized for exactly this purpose: DOS Games and it is able to run as fast and slow as you need it

We do not officially support DOS as guest but nevertheless should DOS work well. But it is true that the processor speed cannot be reduced.
