This has been raised a few times previously on KLOV.
After recently revisiting my improved Free Play ROM hack for Food Fight where I added blinking LEDs as per other Atari games I was asked to look at adding the same for Marble Madness. This game already has a Free Play mode that works well so I focused on just enabling the blinking LEDs when Free Play mode is selected in the settings so that they blink like when in 'coin mode'. This update still shows the high score table and all the attract screens when in Free Play mode.
Thanks to @joemagiera for testing this hack using Intel 27256's.
The link below contains all of my ROM hacks including this one.
