SYS file

SYS files hold palette and sprite data for the game logo displayed in the CDZ menu screen. There's one file for each nationality:

• TITLE_J.SYS
• TITLE_U.SYS
• TITLE_E.SYS

Palettes are stored first, there's space for 45 of them ($5A0 bytes). Following that are 40 sprite tiles in the regular SPR file format, making a 9*5 tiles (144*80 pixels) logo. Tiles are mapped from left to right, top to bottom.

(See cdrom_load_title in cdrom.c of NEOCD 0.31).
