yea. if u want to make it run 'better' in mame, do the following:
1. enable cheats (set cheat 1 in mame.ini) 2. load double dragon in mame 3. enter mame confg menu (default key TAB) 4. go into the Slider Controls menu 5. where it says Overclock CPU: maincpu and Overclock CPU: sub, set them both to 200% 6. slowdown is now very noticeably reduced when there are lots of enemies on the screen
