Creating your own IPFs

Thank you acd2001 for these updates. What I like is how you remove attachments for the older versions as that avoids confusion!

The OP just deletes the attachments from his posts! Looks like acd2001 has removed all but the latest build now.

No new formats but equally a bug fix is welcome too

Super

I would think Abaddons update has now supported the last remaining Rob Northen protections!

[dlfrsilver]

For the record, Barry sent me the IPF made with disk-analyse, and the block/sector 0 is missing from the protection look here :



Compared to the IPF i did with the SPS tool



Look at the downright informations

[BarryB]

Sector 0 is not missing in the IPF or KF dump though?

Cybernoid KF Dump:



It is missing in Nebulus KF Dump:

I will need to take a look as Cybernoid does not show a missing sector when generating the ipf.

Just to help, when i load the IPF in the SPS tool, it says Block 0 is missing or not exist.

Cybernoid protection is in track 00.1 ;

For nebulus, It's a copylock Amiga (the basic version), in track 00.1

[BarryB]

So why is your analyser saying Cybernoid has block 0 (sector 0) missing on track 00.1 but the KF dump in HxC shows it's there?

That's really bizarre!!

Missing in the IPF you sent me. Present in the IPF i made from my own original with the SPS tool.

It's not correct, so i guess that Abaddon will fix that.

Please note that the copylock in Cybernoid is not the same as the one used in Nebulus.

Sorry i fucked up when upload the picture. The one you saw first is the one i did with the official IPF.

With current disk analyse here is what i get with the IPF BarryB sent me :

Nebulus appears to missing sector 0 on the 2 dumps I have. However, the protection check code is identical for both games. Lombard RAC Rally is similar to Nebulus, but the protection check is encrypted, but when decrypted the protection check code is identical as well.

I did a quick check and sector 0 is present, so not quite sure why the official SPS tool is not seeing it, but will look further.

If I take the IPF created by you from the archive on Turran and the IPF created with disk-analyse and make an image of the disk with DIC or RAWDIC, both disks have the same md5. Track 0.1 on both disks is recognized as a standard amigdos track.

I will look into this further.

It can't be amigados. The game use the Rob Northern Type 1a 12 sectors track.

Track 0.1 on Cybernoid is most definitely amigados, but with an extra sector with a sync of a145 for the protection check. The amigados sectors on track 0.1 contain the start of the data for the BOOT file.

This same protection code is used in Nebulus, Lombard RAC Rally, Operation Wolf (one version), Hotshot, Manhattan Dealers, Garfield. Even though the protection code is the same, some games are missing sector 0 and others like operation wolf do not contain valid sectors other than the sector with a145,

At least one version of Operation Wolf uses a new Copylock,

Added Elfmania, Updated the RN a145 format, Updates to several other
decoders to set the data offset

[BarryB]

Thanks for this

Abbadon mentioned Elfmania was far more tricky to do than the ReadySoft decoders, so thanks to him for supporting it
