definitive game + os compatability

[squirrel]

Hi,

I have a CPUNXT1 green pcb board and want to know which is the highest OS version which will work in it so I can bid on some games on ebay. It seems as any ssos  beginning OS/s should work as long as there is no other conflict. There was another thread about this earlier on that promised an XLS spreadsheet with  game and os compatibility but it apparently was never posted? It seems a lot of the confusion may be around the terms CPUNXT1 CPUNXT 2 and BB2. I was thinking a BB2 is a cabinet and you could throw either a CPUNXT1 or a CPUNXT2 board in it. So if an ebay seller is listing a game as BB2 compatible, shouldn't it play on my board as long as the game os is SS0S(or ssg?). It  seems to me the safest way to know would be based on OS versions and game combinations not by cabinet name.
How to tell?
The only other thing I can think of would be I know that CPUNXT 1 and 2 boards had a P3 chip on them but eventually WMS made a board with a P4 on it. Is that what they mean by BB2?

Thanks
