The CAM formats are:
AO PC - 16bit images
AE PC Demo - 16bit images
AE PC - custom hacky MDEC compression stuff.. nightmare
AO PSX - PSX MDEC compression
AE PSX - PSX MDEC compression
There is a tool called jPSXDec or something that you could prob use to decompress the PSX CAMS. Or you could write an actual PSX app to decode them using the PSYQ SDK from PsxDev.net
