I was on my way to my new HS. I got to wave 8 and had 2 men left. Around 128-134k the game reset it didn't retain my score. I was so bummed to get there and have my fame taken away!!
Was this the shot into the corner bug? All the times I played Robotron, I never experienced it. Read about it here and had it happen a week or so later.
You need to either get the blue roms patched or switch to a Jrok board.....Info on Jrok boards can be found easy enough by googling Jrok and steph at hobbyroms can take care of your rom needs....
Don't really see this issue on my home machine, but ran into it in spades at Barcade in Brooklyn last week. Hit the "rug pattern" reset on 5 of 5 games, the last one when I was just getting my game on around 1 million points. So frustrating, so I feel your pain. Keep practicing, you WILL crack 1 million.
