PDI, the new MSX FILE FORMAT for Protected Disks is Finally Created

That interface from Rafael does not have any support to read and write 1.44 disks.
And I know nothing about that chipset from Western Digital.
It would take months to understand it and make lots of tests.
We will try to support it in a new version of DSK-PRO.
But for now I really need a real disk with some overlapping sectors lock for me to study it.
Any can help?

Yes, I do have some jap games and I can let Marcos Daniel take a look on them.
How other games have this kind of protections?

Yes dear ricbit, but I don't have the time to work on it.
Thanks for your help bud.

Actually I have no protected game disks.
I have a lot of brazilian aplication disks with differente locks:
Chave Mestra 1, Chave Mestra 3, Versor, Hello, Aquarela, Série Prokit, Serie Master, etc

But all for Port Based Western Digital chipsets. It will not work there. Just Aquerela can work there because there lock is just a CRC error in 2 sectors.

I need the protected disks from Microcabin, Sunrise to analise the locks. Without them, I can not do much. I don't have the time to analyze the DMK Files to try to write them to a real disk.
I need a real working disk to analyze it.

Those all have the 11 overlapping sectors copy protection, as far as I know. I created dmk files for Xak 2 and Gazzel. Here's the output of analyze-dmk for Gazzel disk 3, for the last track:

-- physical track 79, head 1
 0: AOfst= 158 C= 79 H=  1 R=  1 N=  2 ACrc=472d,ok  DOfst= 202 T=n DCrc=86b5,ok 
 1: AOfst= 815 C= 79 H=  1 R=  2 N=  2 ACrc=127e,ok  DOfst= 859 T=n DCrc=86b5,ok 
 2: AOfst=1473 C= 79 H=  1 R=  3 N=  2 ACrc=214f,ok  DOfst=1517 T=n DCrc=86b5,ok

 4: AOfst=2217 C= 79 H=  1 R=  9 N=  2 ACrc=ce84,ok  DOfst=2261 T=n DCrc=649b,ok

 9: AOfst=5287 C= 79 H=  1 R=  8 N=  2 ACrc=fdb5,ok  DOfst=5330 T=n DCrc=9554,ok 
10: AOfst=5372 C= 79 H=  1 R=  9 N=  2 ACrc=ce84,ok  DOfst=5416 T=n DCrc=649b,ok 

(sorry pasted the wrong data before)

Meaning of this:

Legend:

  AOfst:  address mark offset in track
  C:      cylinder
  H:      head
  R:      record (sector number)
  N:      sector size  (in bytes: 128 << N)
  ACrc:   CRC value of the address block
  DOfst:  data mark offset in track
  T:      data mark type (n = normal, d = deleted, ? = unknown)
  DCrc:   CRC value of data block

Raw track length = 6231 bytes
