This is a very very belated post – although I will back date it to October last year (2011) when it occurred.
Several times in the same week, I finally broke the 1 million point barrier on Wonderboy.
Current best score (MAME) – 1,052,060.
I have since stopped playing the MAME version now that I have my cab running with an original Wonderboy PCB running. All future wonderboy scores will be posted based on original hardware 🙂
