Just got GHWT and noticed the two current X360 [NA] entries on the db actually refer to the same release.
The release in question is
this one which features text in English, French and Spanish. 4809 has the IDs, 105738 has the full artwork and no IDs.
The copy I have, which is missing, is
this one which features English text only and different UPC / item numbers.
Posting this to ask what the proper approach would be to sort this out before submitting my version as a new entry.
