The next block of 512 bytes only has the first 16 bytes written.

Entry Table

The next 1024 bytes contain the file entry table:

Format

First is a header, this tells us how many files are stored here.

Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00000400  00 00 00 01 00 00 00 0B 00 00 00 00 00 EF FC 00  .............ïü.

 u32 - unknown (0x01)
 u32 - Entry count (0x0B)
 u64 - unknown (0xEFFC00)

Then follows a 32 byte entry for each file

Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

00000430  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................

 u64 - offset - Relative to 0x400 (0x400)
 u64 - size (0x2E800)
 char[32] - name (asecure_loader)
