Copying games =/= duplicating?

[Stuart36]

Something that i have always wondered is, if you copy all of the code from a disc directly onto another disc, why does that disc have piracy issues? surely a straight dump would not lead to problems, as all of the code of an actual disc would be present!?

[swedishmeat87]

Maybe the original disc has some Security features maybe ? i donnu... Actually i did a copy of my SF3 and run it on my chipped saturn worked fine. But i never tried it on some of my consoles without chip.

[Stuart36]

well since they are on the disc, if you copy it, you will have them. And i doubt that they will be physical, since it's a CD.

As far as Saturn games go, there's a hard printed ring around the disc that the system checks to see if it's legit that can't be done with a burner.

Take an official Saturn game and turn it over. Look closely at the edge.

Yart's right. You'd have to have the disc specially made which would be expensive as hell. A Rob Webb modchip is the way to go. I had to bridge a gap on the modchip with some solder and then it was just a matter of plugging the ribbons in...dirt easy!

Yep, there's a security ring that would be impossible to write onto a CDR and it unreadable through a PC without some very clever tricks with the drive, it was added at the pressing plant where the cd-roms were produced.

It's literally the most perfect copy protection for an optical media, even if a mod chip does get around it.
Makes you wonder why they didn't use it on the Dreamcast.

[Stuart36]

i would assume that they didn't use it again due to the cost, bearing in mind how much debt their previous ventures had landed them in.

well, thanks for the help; that answers that.

They did use it on the Dreamcast, the problem was that they found a security hole in the system BIOS that allowed booting specially tailored homemade discs.

There were attempts to do the same on the Saturn (one attack vector being the PAR cards ability to boot even with copied games, the other was checking the MPEG card routines and seeing if it allowed for code to be run).

Meh I have a system disk which bypasses the security check. It's basically a blank disk with a security ring which when checked, somehow tells the console not to look for it.

It's a pretty cool method. Saves me having to chip saturns and if they die i dont have to cry and fork out more money again.

Sadly in these harsh times of uni and mass unemployment i just cant afford to have all these luxuries i want.

[Stuart36]

^^^ Where do I get one?

[Aydan]

find someone who's willing to sell one, or look on ebay every now and then.

To be honest I'm amazed I managed to get one!

Again, it's a great little thing to have, when the system disk is done loading just put the burnt copy of a game into your saturn and enjoy.

The system disc was pretty much an official boot disk released by Sega, for developers.

They aren't as readily available as modchips.
