the RPM is not involved on copylock. It's a special sector.

Lethal Weapon use a copylock.


btw,I done more games using powercopy

stormlord => copylock
gods => copylock
rainbow islands => copylock (unless you use the not copylocked version)
rock'n roll => should be ok i think
rick dangerous 2 => copylock
ghost battle - seems is working but there are gfx bugs in my A1200 , this game is not 100% AGA compatible => yes. need no cache and original.


chaos engine aga - fails on powercopy but can be written with wwarp

=> RNPDOS, need wwarp to shorter the inter sector gaps

idem for

assasin se => copylock
alien breed se => copylock
arcade pool => RNPDOS
super frog => RNPDOS

and perhaps all those team 17 games can br written with wwarp

wwarp is made to write back Team 17 games with RNPDOS, but not the copylocked games.

and perhaps the reason because SYBIL was done, because the SYBIL was cheapeast than a MAC drive

I wonder which floppy drive+motor speed control can work with powercopy,
the powercopy' author don't specify nothing which model, which brand????
wtf ?

is there a way to connect a MAC 800k floppy drive to the AMiga?

I created SYBIL to duplicate disks using a single drive (Supercard Ami required two drives). I also created a version of SYBIL to read/write Mac disks on a standard Amiga drive specifically for Readysoft. When Readysoft decided to back out of our deal (after we had already made the fist batch of SYBILs) I created EMPLANT out of spite. SYBIL changed the clock speed of the Amiga, which in turn changed the clock speed of PAULA. This let me "virtually" change the drive speed by changing the clocking of PAULA. You can also create long tracks using a drive that can have it's speed changed via a pot. Weakbits, Strongbits (no flux areas), can all be written on a stock Amiga without needing any extra hardware.

I was not aware that anyone wrote software that supports SYBIL. I will have to check out wwarp. The SYBIL copier/imager was really popular with the BBS crowd because you could share disk images of copy protected disks.

Rob's Copylock uses normal sectors. If you scan the disk it looks perfectly normal. The drive speed (or data clocking) is varied for each sector. The protection times how long each sector takes to be clocked in with whatever controller is being used (Amiga, Atari ST, etc.) Unless you deliberately scan the sectors for time you would miss this. Of course flux copiers duplicated this with no problems.

.

yes the program wwarp by wepl it seems uses your sybil hardware for certain games
try to copy the games turrican 2 or lethal weapon and you will see


btw,

do you know an Amiga floppy drive which have speed motor control built-in?
what about the old Nec FD1035 ? do you know this drive?

[JimDrew]

There were several Amiga drives that had pots for the motor speed control. NEC seemed to have several types.
