for future reference,
if you have a red/green board that has failed and you wish to swap your game over to a new board, you will have to not only swap your eagle bootrom (if it's not the same version as your current one but ideally you'd want the latest version 2.09 anyway) and the security chip (the G4C-US-U or whatever you have version chip) ... you will also have to remove and swap U61 (a surface mounted SOIC-8 chip) off your current board and solder it onto the new board, as there is data bound to your game and security key stored there.
just swapping the bootrom, security key and the games harddrive won't make it work.
on the good side, you can purchase ANY IT games board, ANY color, regardless of the original game, and swap the bootrom/security key/u61 IC's off your broken board onto the new board and be good to go.
on the bad side... you will require a hot air rework station to remove and install the U61 without destroying it or the board. the traces are incredibly fine and if you heat it up too much when you pull the chip up, it'll pull them right off with it. if you don't have a rework station, call around to some videogame repair places (playstations, xboxes etc.) and see if they have one and could do it for you. you DON'T want to mess it up by going ham with your daddy's 500 watt weller... you'll end up with 2 dead boards.
