The Lord of the Rings: War in the North [BLUS30421]

Title is wrong. GameID should be "BLUS30421" not "BLUS-30421" (no hyphen).
Game Title is wrong. Should be "The Lord of the Rings: War in the North" not "Lord of the Rings, The - War in the North".
Just right-click the game in RPCS3, and go Copy Info > Copy name and serial. Then use that as the title, its far easier.

I fixed it for you.
