Format from Maxis Documentation

This information was provided on June 13, 2015 by SimGuruModSquad on [official forums] as part of the Modding Documentation.

The layout will be using the Maxis provided data type descriptors, i.e.: UINT32 vs DWORD

 UINT32   version             // The latest version is 0x20

Format

This is what was discovered early in the process -- now obsolete

 DWORD version	// 0x1a is current
 DWORD offset	// to resource reference table from end of header (ie offset + 8)

 DWORD presetCount? // For all files I read so far, it's 0. It might still be a count
 7STRING		// UnicodeBE
 FLOAT sortPriority	// CAS sorts on this value, from largest to smallest

 // This block hasn't been test for multiple files.
 Byte[22] Unknown
 DWORD count
 --repeat(count)
    DWORD
 // Unknown bytes

 // Resource reference table in I64GT format (not TGI64)
 BYTE count
 --repeat(count)
       QWORD instance
       DWORD group
       DWORD type
