ticket.sys

I'm working on the ticket.sys file format. Here's a summary:

One entry per game. The format is:

    CAM\0                   magic?
    icon length             2 bytes big endian
    title data length       2 bytes big endian
    icon (deflated)
    title data (deflated)
    ?? (deflated)
    block of zeros
    content length          4 bytes big endian
    signature?
    content ID              4 bytes big endian
    another signature?

The deflated streams are ordinary zlib streams with a window size of 31.

icons for all the games I have

The icon with two Chinese words says "instructions".

According to Marshall the icons are RGBA551 format.
