It does have the limitation of only copying the format MDV1->2 or MDV2->1 thoughRalfR wrote: Thu Feb 06, 2025 1:24 pm If you only want to copy from cartridge to cartridge, you can use QLone from Ultrasoft (available from Dilwyn), which copies the random number.
However, this does not work with other encryption methods (e.g. Tankbusters).
Stefan Schmidt, who wrote "QL Strip Poker" at the time, once told me that Talent had given him a specific way to protect the program.t0nyt wrote: Thu Feb 06, 2025 2:00 pmI tried Qlone+ CFORM for West and it suffered the same magic number problems as the other methods on my systems (as I didn't have an original that still worked, only an image of it)
If that protection mechanism indeed attempts to spin-up > 8 MDV units (which wouldn't usually be noticeable on an unmodified QL), then it is quite conceivable that it upsets vMap which does clever things with the COMMS CLK signal and may be responding to the unexpected/out of standard signalling used by that protection...

Yes, that sounds like a plausible reason thanksmartyn_hill wrote: Thu Feb 06, 2025 2:46 pm Hi Tony!

If you really had 8 drives connected, I'm sure the original QL PSU would have quit when all of them ran at the same time.martyn_hill wrote: Thu Feb 06, 2025 2:46 pm Hi Tony!

Actually vMap was preventing formatting with the correct magic number, not preventing it runningt0nyt wrote: Thu Feb 06, 2025 2:50 pmYes, that sounds like a plausible reason thanksmartyn_hill wrote: Thu Feb 06, 2025 2:46 pm Hi Tony!

I'm sure there's a joke in there somewhere, tofro - "How many PSUs does it take to power an 8-MDV QL?"tofro wrote: Thu Feb 06, 2025 5:08 pm
