I have the "free-play"-ROMs working well in my machine.
The attract mode is still available. If in attract mode someone pusehs a stick , the machine moves a ball right up until it fells in the first hole.

Free Play hack v1.2 for Ice Cold Beer
by Pat Daderko (DogP)
Included in this zip is a free play hack for Ice Cold Beer. This is an updated version with attract mode, and added code from Mark Jenison
to blink the start button as well.
There are two ROMs included: fp.bin is the standard free play, fp_mad.bin is a ROM with manual attract disabled. Manual attract mode puts the
ball on the bar and moves it up into a hole when someone presses the joystick during attract mode. There is a DIP switch to adjust how often
it can occur, but no way to completely disable it. So the fp_mad.bin ROM disables it.
Manual attract can be annoying if someone moves the joystick before pressing start, and has to wait for the sequence to complete before being
able to start the game. There is also an automatic attract mode, which does the same sequence (based on time, rather than someone moving the
joystick), which can be disabled through DIP SW3 #1.
Chip U24 (2764 EPROM) is required for this hack. This ROM is for free play only... there is no adjustment to switch between coin operated and
As always, use at your own risk... it seems to work fine for me, but I can't be held responsible for any consequences of your use.
So you just need someone with a burner.
