It works! Mission Accomplished. Mounting the .raw file, replacing the loader file and then re-imaging with rawread to produce a working extended adf file.

If you could chuck new image in zone for everyone, I think that's another one done

Can a normal .ADF be made for real Amiga users?

Nope, because disk is a combination of AmigaDOS tracks and MFM.

If there are any ingame differences or bug fixes, I'm happy to crack it.

I think it still checks the megaprot protection on track 79 though! I made a new IPF with the loader / MFM tracks (minus the protection) and while it loads to the title screen the game then sticks on track 79, so the disk appears to still have the megaprot protection check active! Can that be disabled too?

Gotcha. I'm sure there no differences with the commercial release so definitely not worth it then

I would have thought so, give me 5.mins

Replacement "loader" file that now also cracks the track protection read check.

Please try it out and let me know if this fixes it for you.

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.

Will it not work on real Amiga if written to disk? Can I just write the relevant tracks to bypass and if so how many does it take?

I havent checked if the MFM format of this game can be copied back to a real disk.

Only way to know for sure is wait until someone combines the latest loader file on an extended ADF, then use MFMWarp to image the extended ADF, and then unwarp it back on a real Amiga.

It at least has a good chance now it no longer needs the protection track, and MFMWarp might be able to successfully copy the disk.

No, it still sticks on Track 79

I checked and verified I had the replacement loader on the disk.

Sorry, assumed once it failed the read it would continue, i'm guessing its stuck in the MFM read part.

Give me a second and i'll reupload.

Track read routine bypassed completely, should proceed this time, I incorrectly assumed it would time out of the MFM read of the protection track, but it takes ages.

Try new Loader in zone.

And the WINNER is...…. Sir Galahad

Now it works

and only ADOS + Atari/IBM tracks, should be wwarpable, i'll test that and report back!

BarryB · 28 February 2021, 23:29

Well, seems I've never used WWARP before, if I did it must have been hundreds of years ago and I've forgotten. So uploaded the IPF I made to the Zone so someone else can make a WWP file!

If someone has nice tute on using WWARP, that would be nice! I read the one WEPL has but didn't understand how to process the created WWP file regards syncs / lengths, so if there is a good tute on using WWARP for n00bs, i'm in

What about using this by @Chips :

http://eab.abime.net/showthread.php?t=74301

He mentions using MFMWarp as Amiga is not able to write IPF. If you've already made an IPF then that can be written back via Greaseweazle? It will then negate the point of needing warp tools?

Think the idea was to create a WWP file so it can be written back on real Amiga hardware, not everyone has a Greaseweazle or a Kryoflux to write the IPF back!

Galahad/FLT · 01 March 2021, 00:30

I'm pretty sure MFMWarp will be able to cope with the MFM format of Blues Brothers if its remotely ST based, they typically have a smaller capacity sector format and the Amiga usually can write back a lot of ST stuff.

I tried to MFMWarp the game but on my A1200 it keeps stalling at track 24, might try again.

Galahad/FLT · 01 March 2021, 00:38

In the zone is "blues2.mfm", MFMWarped file of the IPF from Barry.

If someone has a working real Amiga with floppy drive, if you could try and write it back to floppy.

You obviously need MFMWarp, commandline is easy

MFMWARP write blues2.mfm

BarryB · 01 March 2021, 01:54

Hmm... Tried in WinUAE writing blues2.mfm to an Extended ADF file, stalls when writing on 'Analysing Track 24 Head 1'? Downloaded MFMWarp from WHDLoad and created my own .MFM image using INDEX copy and that too stalls when writing on 'Analysing Track 24 Head 1'? Track 24.1 is no different than all the other MFM tracks, HxC shows it as 10 sector MFM, just like all the other MFM tracks are 10 sector?
