Title: Mame Frame Skipping
Post by: IG-88 on August 15, 2007, 09:23:02 pm

I was just wondering. I am running a bartop with some very old hardware. It has Game Launcher with DOS mame v.55 and I was just wondering if there is a way to have individual games set with different frame skipping rates and be able to keep them that way. For example Asteroids Deluxe runs great on this system but the original Asteroids "studders" really bad unless I skip about 5 or so frames. Don't understand why but it does. Only problem is when I exit the game and come back to it the frame skip is back to auto again. Any suggestions?

Copy your mame.ini and paste it in the same folder. Rename it astdelux or whatever the name of your rom is. Change the lines autoframeskip to 0 and  frameskip to 5. Lauch your game and press F11 to see if the frameskip is set at 5. You can also change the samplerate to something lower to see if it increases performance.
