Triangel7D,
Wow, it's been a long time, since I have been on here. Ran into that problem last year and couldn't solve it. Got busy with other things going on and haven't really worked on it. One of my New Year's resolutions was to get my game back up and running and then finish it all up.
So I logged on today to look and see what's new and ran across this old post. I have been considering reloading it with just the 32 bit version as the 64 bit version gave me all kinds of problems. The main reason I went to 64 bit was my plan to upgrade the processor. Well since I never got the 64 bit version working I never upgraded the processor. Was hoping to take advantage of true 64 bit.
So if there is a solution, preferably without Xpadder I would be interested. Otherwise I think I might go back to 32 bit Windows XP.
Glad my Taito build was a big help. I really liked the Taito cabinet, but wanted a little more, so I upgraded to MKII cabinet that had been converted to NFL Blitz. I liked the larger control panel and it is better for 2 player. The cabinet doesn't get a lot of 2 player action, but when it does the extra room is great.
