The rom needs redump message can mean essentially nothing to users (in some cases) like if it's a pal chip that isn't even used in the emulation. Just ignore it. If you tell me the exact game I can probably tell you more but you're getting into an area now that is not really something that can be fully explained to a new user in a quick reply. Short answer, it could mean something to you or it could not. If it's a game where that didn't happen before in 122 then the game will probably play just as well as it did before now in 161, just ignore the message.
