This was the re-release where the screen says "No Dongle Required" - don't remember one that featured a dongle as protection but it's possible.

This image is correct, but maybe due to Pasti.dll the game may still fail on start.
In Steem you're advised to save a snaphot right before pressing F2.
The game reads sector 79/9 only twice and checks first 16 bytes for fuzzy data.
There are other images that will fail all the time.

The "no dongle required" text is only there because the Amiga version do require it and not the ST... i guess it was because the joystick ports were so difficult to reach on the ST and maybe the dongle not even fitted underneath the ST.
I guess this is the same reason the ST version of Robocop 3 do not have any dongle while the Amiga version does.

According to Marakatti so did the Atarimania pasti work in Steem but not any longer? Is it the pasti.dll maybe?

[Avanze]

This version works fine with Steem, but the Atarimania one does not. I just happened to be checking some 8bit to 16bit game conversions at the time.

[Marakatti]

Fixed with new download.

Many thanks for the bugreport

Mug UK.. this was really a re-release? Or you only suspected it was because of the "no dongle required" text?

Well, the image is actually bad, probably the disk itself is bad.

As Steven described, the program checks the first 16 bytes of the weak sector. Reads the sector twice (using xbios call) and computes an 8-bit checksum. If the checksum match the protection doesn't pass.

The problem is that the sector is not weak enough, is too stable. According to the image there is a single weak bit on those 16 bytes. So chances that two readings will be identical (let alone that a simple checksum can match anyway). And this is for the image that works sometimes. Other images don't have a single weak bit on the first 16 bytes, so they always fail.

This indicates a bad duplication. The sector is probably weak enough depending on which drive is read. I have seen this already in a couple of other cases.

Muguk, Do you still have that disk? Any chance to make a flux low level dump?

I can have a look but I doubt it as I sold off almost all of my collection many years ago. I've got a few boxed titles left, plus a lot of unboxed (i.e. disks only, or disks+manual) left.
