Attached my latest list of cracked images.
The interesting information here are titles with the same "Protection Type".
"Trains (1983)(Spinnaker Software)(US)";"(pha+tim $9 / 9)";"Spinnaker";"Spinnaker";"Spinnaker pha";"a";;
A year or so ago, this one intrigued me, (before I knew of your efforts on this title) as the ATR from the "Best Games collection" seemed to work fine when loading in an emulator, via SIO2PC, and when written out to a real disk it also worked fine on a real Happy drive (in happy mode) but would fail when set to *unhappy* or on a stock 1050.
Looking at RespeQt logs, i could see it would fail after reading sector 9 about 50 times, which clued me into the timing being 'too fast' was actually causing the commonly shared versions to pass the protection checks!
Of course, sector 9 on an unbuffered 1050 will only read sector 9 once every revolution... so this was my inspiration to learn how to create a custom track with the Archiver, and made a track 1 on a new disk that had 19 complete sectors on 1 track, with 2 sector 9's. (one of them in the middle as usual, and the other at the end) I was not sure how to copy the data from the existing disk to the track with the custom format, so I basically just did a sector copy a few times using my-copyR afterwards in hopes that eventually both sector 9's would be written with data, but I'm not actually sure the check cares what data is in sector 9, just that it doesn't take long to get it.
Regardless, I was pretty chuffed to have 're-created' the protection using the Archiver software (emulated on a Happy 1050) - and the rest of the disk was formatted with the faster Archiver/USDoubler 'chicago' interleave, so on a stock 1050 it still loaded 10% faster than the regular interleave... (so kinda better than the original potentially?)
I was going to mention this title at some point, but if you've already cracked it properly that's great!
There's another vandalized cracked version in ED format too, not sure what they needed the extra space for...
