How to rename title in dolphin

[BridgetFisher]

Thank you for the replies and other comments, still stuck trying to figure out the title. I did play the game its a racing game and did save the banner. Problem is it still says "THE MARIO". with all the games I have please understand yes I can forget what game is what. I also have a COD gamed called COD h337.com, again after playing it it is stuck with that title but does who a banner. If anyone has tips or tricks to solve the issue please post them here. The discs I got from the internet. Just got my wiimote and I really want to play more games but its disheartening not knowing what some of the games are.
