You can't compare the CPU requirements of a DOS game with the CPU that is required to run it in DOSBox. DOSBox uses up a lot of resources in emulating hardware by software. You can have a factor of over 100 between the original MHz requirement and the one with DOSBox. About RAM, DOSBox doesn't automatically take over all your RAM for DOS programs. You may have to change its settings to increase the RAM available inside DOSBox.

ScummVM on the other hand is a native application for each device that reads the game data files like the original engine for DOS did; this means the original CPU requirement is meaningless too, but in this case there is no overhead so the requirements of ScummVM in your phone will be equally low.

I don't play DOS games in the phone, but I do have emulators for several consoles installed, since those games have simpler gameplay and controls better suited to phone interfaces. But we can't discuss console gaming very far in this forum...
