I've done more than one search through more than one forum, and I've not found any answer or discussion specific to what I want to ask.

Some time ago, I discovered that by using a slimline PS2 and rigging the sensors, you can make the disc spin even while the lid is open. As a result, one can swap out a game for a backup copy, allowing the backup copy to be played. However, this will only work for PS1 games.

The reason why this is successful is because the security checking component of the PS2 console is being tricked into thinking you have a legitimate, factory made disc. What I want to know is why nobody has, or ever will discover a way to trick a PS2 into doing the same with PS2 games?

Of course, I can buy a modchip or swap magic, but that's not good enough for me. My personal goal is to find a way to play a PS2 backup on a PS2 that is un-modded (save for the sensors, mind you).

During a security check, a PS1 disc speeds up and slows down, prompting a switch. Although it is quite different on a thick, original model PS2, it can still be done if you remove the top shell of both the PS2 and the disc drive. The pattern for this model is as follows : Security check -> reads data -> security check.

Now that I've mentioned two examples of security check patterns, does anyone know of such a pattern when booting up PS2 games?

I've chosen this forum because I'm sure many of you are walking encyclopedias on the subject. I know I'm new, but please don't flame me. I'd really appreciate some info so that I can accomplish my goal. Thanks guys.
