I'm sure some coder could crack; if they can be bothered doing a coverdisk version.

That's not funny is it. Grr

Or if someone knew the code! I'm hoping it is the same each time unless a keygen is needed.

Looks like a one time unlock. Ring up the number, hand over the given code and your parents credit card details and get an unlock code in return which writes to the disk to unlock it and not get asked again.

Totally not a scam ..

So what is the code lol...

Someone please upload whatever it is that needs cracking in the zone ffs!

All this dicking around that can be resolved by able peeps

Lol but not just crack it... it would be cool to have keygen so it could be unlocked rather than the code removed

Well, what a load of hopeless shit that was.

So, loads up the file "loader", which is internally packed with Propack which then depacks to an absolute address at the top of chip mem.

Generates a random code.

It then calls a Copylock with the disk read routines not activated, which then calculates the code you've given versus the generated code at run time.

The Copylock is a load of complicated bollocks, because the end result of its complicated hidden key routines, is that register D0 on return has to be ZERO.

Once that is achieved, it simply saves a new "Loader" file over the original "loader" file which will then correctly load up the "MAIN.PRG" file and the game will run.

Only problem I have, is I don't think you can save a file to a .RAW image, which means the disk image can't be modified unless someone knows differently?

The disk format is a mixture of AmigaDOS and MFM, so would need to be cracked for use on a real Amiga, but I very much doubt this version is any different to the retail original unless someone knows different?

The only way this gets "fixed" would be if someone has the original coverdisk, copies the new loader file onto the disk, and then re-rips the disk to RAW format which would obviously make the change permanent.

With write protect disabled, winuae should generate a new adf file in the emu folder. 'filename_save.adf'
Another option if the above fails is to generate an extended adf version with rawread.

Disk can be converted using Keir's disk utils. I can make an IPF and SCP image and I have tested and it writes okay but IPF resulted in writing of only a few tracks then skipping to track 40. SCP wrote all 79 tracks. Both loaded till the loader but I suspect only the SCP version will contain all the data?

Didn't know that, unfortunately the file it generates doesn't work.

So I thik the extended ADF is an option, or I can provide the modified "loader" file that someone needs to copy onto their original coverdisk and then generate a RAW file and it should work as RAW seems to duplicate the MFM tracks fine.

Seems a lot of effort for a game with no discernible difference from the original retail release other than a slightly different disk structure.

Let me make an IPF out of this RAW dump.

[dlfrsilver]

It uses the megaprot 91 longtrack protection made by titus, with 10 amigados tracks + all the remaining tracks in Atari ST track format 10x512bytes sectors.

IPF in the Zone.

Can the cracked loader be uploaded?

Just out of curiosity, did you create this via Disk-Analyze?

UPDATE: Seems like you have done some wizardry! Your file writes completely whereas mine did around 10 tracks then skipped to track 40 then ended! Only the .SCP version I made via Disk-Analyze went to 79 tracks.

How did you make this one?

Denis has the full 'Gold Shitting Bricks' SPS Analyser for creating IPF's

[ItsTheSmell]

So have you guys managed to solve it?

Lol - how lucky we are... at least we know there is someone capable of making use of raw dumps lol.

Still waiting on @Galahad/FLT to work his magic on the disk.

[Galahad/FLT]

Apologies. Replacement "Loader" file in the zone.

If this can be copied to the original coverdisk, and then the coverdisk re-imaged, it will then work under emulation without pissing about calling telephone numbers.
