Calling [Wii] unk compress

[TTEMMA]

Hello. I need help with the definition of the type of compression in the game Calling.
Attached files contain a structure
4 bytes - the size of decompressed file
4 bytes - the type of compression (0x00000001 - UNK, 0x00000007 - zlib)
Then, presumably - the compressed data.

I hope for your help

Usually on wii the dev use the nitrosdk compression (lz77wii in quickbms) but this one doesn't seem the case.
I made a compression scanning from both offset 8 and 12 without having good results.
