picked up a DM wednesday night. demo time is installed and i was told that i have all the originals, too. is there a quick layout of which roms go where? i wouldn't think it'd be that hard, right?
update: factory lx-4 is installed now, but the claw won't work: magnet error.
final update (i hope): turns out there are scratches on the cpu board under the game rom socket. this is probably from the previous owner rough-housin' when swapping roms. hindsight is 20/20, but it actually makes a lot of sense now.
every once in awhile i think i could have done this. i really don't think so, however. i got good fairly quickly at using a flathead screw driver to delicately pry the game rom off the board. my cpu board is really scratched up. someone messed this up many times. here's how to do it right:
you wedge the head in on one side. you don't need to stick it in far; maybe 1/8 inch. then you rotate the head back and forth a little bit. just enough to get the pins popping on that side a little. now you have a little more space to stick the screwdriver in further. you can go about 1/4-1/2 inch in. repeat the head rotation step and you'll be good to go about an inch or maybe the whole way. the most important thing is make sure you're as parallel with the board as possible, or you could develop scratches on the board like mine had. once you have the screw driver behind the entire game rom, rotate back and forth until the rom is completely loose. it doesn't take much effort at that point. good luck.
final update 2.0: it wasn't the cpu board, scratches and all. the claw wasn't getting far enough back over the elevator to pick the ball up. it would work with the demo time rom, since there's less light show on that rom. this is what i'm thinking anyway. less lights means more juice for the claw magnet. it could pick the ball up with the extra juice even though it wasn't directly over it.
figured this out when a buddy was over playing and it stopped working. yeah, it worked with lx4 for a few days after the cpu board swap. so weird. he was standing at the side and said it looked like the claw wasn't back far enough. i never noticed because i was always testing the game from the front of the machine, and again, it worked with the f'n demo time rom every single time.
well, i think this is it, guys. thanks for all the help the past 2 months. i owe some food and drink at allentown, that's for sure. now i can actual play this thing without any worries about if the damn claw is going to work. gotta work on those scorezzz!
