KOF 96 custom loading screen (LOGO_E.PRG).

Optional structured files consisting of an index, fix and palette data for CD loading animations.

The BIOS loads these files after checking the IPL file if they are present at the CD's root, at address $120000 according to the console's nationality: LOGO_E.PRG, LOGO_U.PRG, or LOGO_J.PRG.

Other file names can be used for in-game loading screen (LOGO_BDM.PRG in KOF96 for example). How are these specified by the game ?

See install_progress_fix() and check_screen_data in neocd.c of Raine.
