hamsterball ps3 archives

hi, could someone see if there's a way to extract the .ga archives from hamsterball ps3? thanks in advance.

There is a "jkGA" magic at the beginning.
The TOC at offset 0x24 is probably encrypted.
The archived files are probably compressed or maybe it's just their format (0x11223344 followed by some fields before the compressed content).
I don't have other ideas.
