I know there are other topics about this problem, but i just can´t get Dosbox running properly on my MAC.

I´ve only tried to run doom2 with dosbox, but I only get like 1 frame per second. I tried to speed the emulator up and set frameskip to more than 1, but the game runs like shit anyway.

I have a Powebook g4 1ghZ, so i think i should have a good enough computer to run doom2.

Could anyone help me? Please. I have so many old dos games that i wish i could run on this superb mac.
What shall I do?
