okay since we have the wiki I guess, time for a picture dump...
Blazing Star - 48,915,370. All clear.
Shock Troopers 2nd Squad - 10,770,450 (Leon). Not my best, I did 14+ mil several times back in the day but have no pics of it... that score came from a Las Vegas meetup in January 2004.
Strikers 1945 Plus - 816,600 (2 lives + extra at 600k). This is a really old and bad score but whatever.
Zupapa! - 12,367,400. Had a better score but it got wiped before I could get a picture. Oops.
And while I don't have a regular pic of it,
I have a video on youtube of me scoring 32,037,800 on Shock Troopers. It's not the greatest quality, but it was played on an arcade machine and all, so I think it should count in lieu of a picture...
