I'm getting one of those HUGE 2-part arcade machines with NFL Blitz 2000 and NBA Showtime. I was wondering if anyone knows where I could find a summary of what was updated/changed from the various board versions. I have a feeling the board I'm getting isn't the newest, version 3.0 and am wondering if it would be worth the $75 to buy the upgrade kit that is available on ebay.

I found on some site for NBA Showtime that version 1.5 to 2.0 added Jason Williams and Paul Pierce. Most every other google search yielded results for the console versions.
