Disk image is OK, but many folders is broken and unrecognizable. We upload this image to your FTP (DiskAU9380.rar).
Please, see in this image.

0000 parameters is correct.

I don't understand. How make it?
Log filter after execute block_number 0000 for sector 0x4200 and marker 518/519 is:

Bank Space: 0x0
Cut begin: 0
Full blocks: false

Banks: 1
00 / 0x000 / 0xff9

End


And next....?

For block_number / 0000:

Marker 518/519 mean:
Code:
Block_Number = byte[518]*0x100 + byte[519]

In other words 16-bit number: 8-bit from 518 + 8-bit from 519

Marker 519 mean:
Code:
Block_Number = byte[519]

In other words 8-bit number from 519

In this flash 518 byte is not block_number.
Its bank_number.
