i can run them on psx but not on the real playstation, without a modchip can someone explain to me please why cos it seems very right to me that no game should need a modchip if its patched.
if this is not the right please to post this then just shut it down dude.

Because the PlayStation can't read copied discs natively.

Patches are created for various reasons. Some are trainers, some are region switchers, others are for getting around copy-protection.
Getting around copy-protection won't make the PlayStation magically boot copied discs; it'll just get around the targetted copy-protection scheme that is supposed to kick in when the game boots up and detects some kind of discrepancy. To get it to boot up in the first place, some modchip is usually needed.

ok i see, you were a big help thanks a lot.
but what kind of copy protection can that be if no one can patch it, i mean guys are getting around starforce without much trouble, and some creepy old sony cd protection is supposed to be unbreakable, this seems unbelievable to me.

I'm not sure what you're referring to... I didn't say the patches don't work; I said that they're more-or-less useless without a modchip.

thats it, how comes that none can make a useful patch that would make the playstation boot a cd.

Because the problem isn't just a software-based issue; it's a hardware (or a combination of software and hardware) lockout that causes copied discs to not work.

aha i see you mean because of the fact that commercial writers cannot write subcode data (or some other hidden data), right?
but wouldn't some bios patch also do the job?

en.wikipedia.org/wiki/PlayStation#.22Chipped.22_consolesThe modchip basically sent the requisite "SCEI", "SCEA", or "SCEE" strings to the proper places so that a game from any region would boot, but the side-effect was that any recordable media could boot as well. As for modifying the BIOS, how do you expect to modify it without homebrew software (which would require a modchip in the first place)? If you had the ability to modify the BIOS, then you already have the ability to boot any other recordable media. Meaning that it'd be pointless. I'm not even sure it was the BIOS that received the 4-character string anyway; it may well have been some other piece of hardware that received the sequence first and determined whether to allow the media to boot before going to the BIOS.

Basically... it needs to be a specially created disc. The real Playstation can basically tell if the game is real or not from the disc itself... If the disc is burned, the Playstation can tell that from the way the disc was made. But a pressed disc (which is different than a simple burned disc) does the right things for the Playstation to know it's real. That all, of course, is a *vast* oversimplification, but for all intents and purposes it gets the point across.
And no, there is no cheap or easy way to create a pressed disc. No matter how you look at it, expect to pay much more than a modchip even to get just one disc pressed, and that's only if you can somehow get that done. Getting the equipment to do it yourself is about as difficult and much more expensive than a person would ever want to invest in.

hallo gamemaster, cant you just tell psx author to implement that dualshock-normal pad switch into psx 1.14, and also an iso browser would not be bad (like on project 64)

As for modifying the BIOS, how do you expect to modify it without homebrew software (which would require a modchip in the first place)? BIOS can't be modified/replaced because it's on the ROM. The only way to do that is to put a BIOS on the 512 kb SRAM and replace the original ROM. One would still need to know how to modify the BIOS to accept any CD-R (I only know how to change the region (eg. original europe disc could be booted on american console)). Not to mention that this would be way more complicated and expensive then the modchip solution...

[SNIP QUOTE PYRAMID]
hallo can someone tell psx author to do that??
and i think you are right about that bios, but i have read an article on the web that one can just patch ps2 games and play them with no boot chip.
ok sorry, i got it now one needs gameshark sd for this method i didnt see that.
