The question I had in the above post still stands. However, I can verify that identifying an unpatched version by the pictures on the back IS NOT RELIABLE.
Check this out. The game in my PSP came straight from that case, and I bought the game, new and sealed, from Best Buy. It's a 10041.
Sorry about the image being rather large; I wanted to make sure that the PSP screen was readable.
This kinda sucks
Edit: Oh, I forgot. It's not very clear in that picture, but the box is copyright 2005.
