The game I’m trying to run is Legend of Heroes 3: Prophecy of the White Witch for Windows XP. I installed XP in VirtualBox, but unfortunately, the game logic seems to be tied to the processor speed, which makes the game run at a blazing speed, making it unplayable. Same when I tried running it with Wine. I should probably mention at this point that my host OS is Linux.

The game was originally meant for a Pentium II at 300 MHz or higher (specs here), so that’s what I’m aiming for. VirtualBox doesn’t seem to offer me the option of setting the processor speed, so that’s out.

Are there any other options available, outside of running out and buying a 20-year old PC?
