To be honest, after combing over a few of the PDF's in PsyQ, they don't do a real good job about explaining it to be honest. Even in their CDGen 1.0 Windows 3.1 application, they don't even show system.cnf or any executable at the beginning of the disc.

But I did find a rather obscure rant about not letting people use the CDGen burning stations for the cha-cha-baby?

To be honest it's rather comical, but at the same time, I didn't see anything specifying where or how the layout should be. The only .cti example I saw was in regards to XA interleaving, and it was a .cti with only a single .str and .xa file, no executables whatsoever. It obviously stands to reason that putting the executable after the system.cnf at the beginning logical as system.cnf would fit in part of just one rotation of the spiral, and the executable following immediately after, requiring really no seeking. I guess they just assumed they'd know to do this. If I'm wrong and one of these PDF's though do state otherwise I wish I knew which one did.

I've checked too and that doesn't seem to be explained indeed. To be fair, it's not that big of a deal anyway but that could have been added as a small note still. These paragraphs in the 2nd screenshot are hilarious though :lol:

A SYSTEM.CNF file isn't required because the BIOS will look for PSX.EXE by default and apply the default CNF parameters. In their example though, they should have at least shown the PSX.EXE file so it's less confusing.

I believe in Stealth Unlocker, I patch out the ReadTOC commands on all or most BIOS revisions. This was done mainly so Japanese units could utilize the Swap Trick on newer hardware versions. But a side effect of that means you might cut some time off of the boot up process.

Games with anti-piracy checks vary to some degree. Basically earlier titles it's a bit more varied/wild west. But past a certain point there was a fairly standardized anti-piracy module. When using a DTL system or the security unlock you can see run into issues with these games because the different behavior can be detected where as the stealth modchips do a reasonable enough job of simulating the response of a licensed disc.

Stealth Unlocker contains patches for many but not all games containing anti-piracy code.
