Need cap value from Midway Wolf unit (NBA Hangtime, MK3, etc)
I've got an NBA Hangtime that had some physical damage to it. I resoldered one of the ram chips but I just noticed that a capacitor was also knocked off because I can see where the solder points look broken. The cap is C194 as seen in the link. If anyone has this type of board and can tell me what value the cap is, I'd appreciate it.

The problem I'm having and maybe it's unrelated to the cap, is that when I boot up the board, it will go through the diagnostics, fail one back of ROMs and then go to a black screen. At that point I can actually coin it up, hit start, and it will play blind. I know the monitor is fine because it works with other games. I wouldn't have thought a small capacitor could do that but who knows. Can I just bridge the solder points as a temporary fix to see if I get the picture back?
Incidentally, the rom banks that fail are the ones attached to the ram chip that I had to resolder back on. I did make sure that I had continuity between every pin though.
