[Request] .pac format for PSP (Magical Girl Lyrical Nanoha A's) - szfzafa - 04-21-2011

The game is called Magical Girl Lyrical Nanoha A's Portable: The Battle of Aces.

Here are some samples of .pac package, from ?:\PSP_GAME\USRDIR\
http://www.gamefront.com/files/20246953/pac_samples.rar

They contain .gim images/textures and .gmo 3d models. You can see filenames inside them.

Also, I found some bytes with certain meanings:

But still cannot get the correct file context. Maybe it's using a LZS algorithm.

Anyone take a look into this format would be a great help.. thx~
