I don't think Aluigi was able to figure out this format...

Arika (They published this game.) has the GAME.DAT format in pretty much all of the games they've published that I've seen.

You should have also an index file because GAME.DAT is a raw container without headers ("ALZ1" are the aligned archived files plus other files).

The other file in the game is INFO.DAT http://puu.sh/kE3D0/5d74179e0e.DAT

I guess INFO.DAT is the index but it's obfuscated.
Probably the only work-around is scanning for some signature like ALZ1, RSAR and so on but the compression algorithms (even if they look simple) may be not easy to find, I already did a quick test with the scanner and had no good results.
