If "special segment" flag is set, 0x214 bytes are read from CfgS:GetConfigInfoBlk8 block 0x70000, and then copied to the special segment given. If the reading fails, zeroes are written in its place. The purpose of this segment is currently unknown.
Each segment record:
| Offset | Size | Description |
|---|---|---|
| 0 | 4 | Offset data |
| 4 | 4 | Start addr in 16-bit words (must be < 0x20000 for type 0, < 0x10000 for type 1,2) |
| 8 | 4 | Size in bytes |
| 15 | 1 | Mem type (0=1=0x1FF00000+,2=0x1FF40000+) |
| 16 | 32 | SHA256 hash of segment |
