The default settings for Marble Madness (set 1) from MAME37b15 onwards are now easier than before. The defaults for all the other sets are unchanged though.(posted 8904 days ago)Tommi Tiihonen has the top score for this rom done on the older settings, it was a great game done with a trackball and shows a nice trick at the end of the ultimate race.
However, what is the rule? Anyone now attempting a high score for this rom gets 15 seconds extra time!
