There's a SHA256 of the data at the beginning of the file. After the sha, there's some stuff that contains UTF-16 text of the game name and publisher, then image data begins.

There's a SHA256 of the data at the beginning of the file. After the sha, there's some stuff that contains UTF-16 text of the game name and publisher, then image data begins.

The image data has a header of 2 little-endian shorts for width and height (128x128 for most icons), then two bytes (20 08), then RGBA data.

The image data is given as Truevision TGA and usually starts 0x2050 bytes into the decrypted buffer.
