I can recreate the protection track and verify it passing. It could be something special with track 16 as that is the same track the has issues on the other raw dump. If I get some free time I will dig into it further.

Don't waste your valuable time for it. New dump from a fresh copy is comming...

Hi Abaddon,
Just uploaded to TheZone alternate version of ABC Chemii published by TimSoft:
ABC Chemii (1995)(TimSoft)(PL)[a]

It's decode properly(?) in disk-utilities but won't work in WinUAE. Could you take a look?

I took a quick look at this, unfortunately it would be a lot of work to add support for all possible versions of this game/application due to the fact that the offsets for the protection are stored at track 67.0. Currently disk-analyze reads tracks sequentially and it is not possible to read track 67.0 to get the offset then go back and decode the tracks. I will add support for this version. Will upload an IPF to the zone this weekend.

At least for za zelazna brama the offset were store on track 0.0, so it was possible to support all variations of this one.
