and i was bored,... well no its driving me crazy that i cant figure this out so i have tried 3 older versions of LB fresh installs on 3 different PC's and 3 different versions of Mame, re downloaded just packman rom for quick testing and none of them will work at all. All do the same thing. All run pacman just fine through mame standalone. PC's all running windows10. That testing being done, do you think a windows update may be an issue since there was on last week? idk running out of ideas.
