I played Hard drivin when it was new. not long after they converted it to race drivin. The only difference being a new track. I would imagine the hardware is the same. It gets boring after awhile. i would think if you could link 2 together and race against a friend it would be fun
an l-pad is used after the power amp. The pot on the PCB is used before the amp.
just use an l-pad that matches the impedance of the speaker. usually 8 ohms. 15 watts is fine. the speaker on my galaxian is only marked 3 watts.

i plan on installing something like this on all my games near the speaker on cabs like galaxian and ms pac. won't be very noticable.
turn the l-pad all the way up, then adjust the pot on the pcb to the loudest level you...
It's pretty fun to watch a couple play Space Duel (linked) and blame each other's "driving"
It would be fun to link 2 games together to have 4 players at once.
