Might need to turn off "hide extensions for known file types" in folder options. There's should be only two in there: loadscreen.bmp and loadscreen.jpg. The game uses loadscreen.jpg to load the game.

Yes, Batch 06 are Lineage II. Batch 01-02 are from EverQuest II: Legends of Norrath (except #08 which is from Last Chaos), Batch 03-05 are Atlantica Online.
Uploading more when I can.
