Okay! I just got myself 261,150. Funny, because when I was approaching the end, I was thinking the score to beat was 266k and thought I fell short. Then I saw your update!
I used to be pretty good at this game. I remember playing once, playing one game for 6 hours. I know this because I rode my bike to the arcade so that I was there when they opened at 11am and had to leave at 5p to be home for dinner...lol. At one point, I had all top 40 scores on the machine...and it was a very popular arcade. Since it only allowed for 5 entries of the same initials, I had stuff like TJB, TB_, _TB, T_B, TJ_, _TJ, T_J, etc.
Ever since MAME though, I really didn't have interest in playing. Too slow at first, then too fast. Now, I'm finding the love again.
F12 isn't as easily accessible right now so I went with the camera...
