07 Analog Controller SavestateAfter the header comes a compressed savestate. If the movie starts from power-on, the "savestate" is only 4 empty bytes. Memory CardsAfter the savestate come two compressed memory cards. If the movie starts from a clean power-on, the "memory cards" are only 8 empty bytes (4 for each one). Cheat ListAfter the memory cards comes a compressed cheat list. If the movie doesn't use them, the "cheat list" is only 4 empty bytes. CD-ROM IDsAfter the cheat list comes the CD-ROM ID chunk: 000 1-byte char: how many CDs does the movie use
001 9-byte string for each CD: CD-ROM ID of each CD used Controller DataAfter the CD-ROM IDs, comes the controller data. Bytes per Frame04 Mouse

06 Analog Controller (The other controller types are currently not supported by PCSX.) There's also an extra byte for control functions like Reset, Open/Close CD case, etc. So, if the movie uses 2 standard controllers, we know it will use 5 bytes per frame (2 bytes for player 1, 2 bytes for player 2 and 1 byte for control functions). Frame DataThe corresponding bytes indicate which buttons are pressed at each frame for each controller. Standard Controller 000 2-byte unsigned short:
