Dogmaus: Another cool thing, finally La-Mulana is running on my laptop at normal speed and I can play it. Years ago it was like in slow-down and I could never figure out why. It kind of solved by itself. Maybe some upgrade that was needed.
Just watch your CPU temperature. I've had that game overheat my desktop (even before the cooling system stopped working) and cause the computer to shut down.
Also, watch your battery life.
Be prepared to get stuck at some point, not knowing what to do in order to proceed. This game has adventure game elements, and that aspect of the game can be quite difficult.
