I am in the middle of an extensive and mildly OCD reorganization of my ROMs, and I come across things that require fixing. I'd like to be able to contribute these discoveries to the project. I'm definitely not one to spam a bunch of BS, I like to stick to the script. Here's one I just found from the Xbox 360 DAT:

"Halo 3 - Essentials (Spain) (En,Ja,Fr,De,Es,It,Pt,Zh,Ko) (Disc 1)"
http://redump.org/disc/101061/

The category of this one is listed as "game" but is actually "bonus discs". The only "game" it includes is a freely available flash game. The version from the (USA, Japan) region is labelled correctly.

Thanks!
