WOW Nemesis! A name from the very long ago past! Nice to see you're still about.
And DOUBLE WOW talking about sega H1 - THE holy grail system...
I have one of each game on the system H1 but one is in use and the aqua is a spare for my cool rider cabinet.
To be fair, the mame emulation of cool riders is very good considering the hardware. Aqua stage not so much. That said... aqua stage board don't do much either without the pinouts or knowledge of what strange and wonderful things it needs wiring up.
If one board goes bad or sell the cabinet you will be first to be contacted as it's in my best interests to get this documented. I am also around and happy to run tests on the H1 hardware should anyone require.
