According to the PSXCPList the NTSC Dino Crisis 2 has a antimod code, but it doesn't work properly.

I think that probably explains why it can be copied and played on my modded ps1 without actually modifying the CD image.

By the way i clicked on the link you supplied and it says the site is now closed

Is that supposed to be a list of games with anti-mod protection? I have some of those games listed and they work perfectly (originals imports and backups) I don't actually have any PS1 games in my collection that will not run

Yes, but probably not 100% complete. Direct links doesn't work. Check the A-Z section for more details.

I chipped hundreds of PSX back in the day, depending on the models the wiring was different.

Now bear in mind that "the day" was about 10 years ago or thereabouts, and my brain has grown considerable rust since then, so the following could be flaky. It also pertains to the Australian PAL models, but I guess all the PALs were pretty much the same.

1002 - the original with RCA jacks on the back as well as the standard video output. Needed a crystal installed to display NTSC, and had lots of laser issues. Repaired uite a few (parts etc)

5502 - lost the RCA jacks and also needed the crystal. This gave a more reliable laser but seemed to fail more often.

7002 - reliable unit, able to run NTSC games by bridging a couple of solder points.

7502 - very reliable unit, also ran a bridge to run NTSC

9002 - reliable unit, easy to mod, NTSC bridge as above. Had the parallel port removed due to the popularity of the game shark cartridge.

So in summary the 1002 and 5502 were the originals, and the later models released for minor improvements, possibly integration of PAL/NTSC together to save making two entirely different boards, and I guess each upgrade was designed to thwart piracy. (which was a waste of time)

I'd still have my pic programmer and modchip source code lying around somewhere, with about 50 blank pics and one erasable pic. Perhaps its time to get it out again... I picked up an original PSX a couple of months ago and havent gotten around to modding it yet. Just need to find my diagrams.

...and a few more details about the pal/ntsc mod please.

is this an either/or mod, or does it allow both types to be run on the psx? (mines a 7502)

I have a unit with a non functioning mod. I never got to find the chip for it. It's an old PSX, one of the first (which already had the AV port)...

Anybody has a clue where to get one of these chips? The installed chip allows for country unlocking but not for cdr playback.

just some clarification pls.... I was under the impression that the newest stealth modchips used 6-7 wires , and the the 4wires onew where the older versions that did not "sleep" after boot... is this true or depends on the chip?

The SCPH-1000 model was the very first PS1 and was only released in Japan.... It is also the only PS1 to feature an S-video port. If your one works with PAL games then it is best to assume it has already been modded by someone ..... does it still work? The early ps1 consoles in all regions were notorious for breaking down... it first starts with FMV scenes skipping... then refuses to work! But some people are lucky and still have the original launch consoles

Hmm... It's been years like I said. I have a few pics still burnt up from the good old days, pm me your address and I'll send you over a couple to try.

It was either, you just had to either bridge two solder points, or run another wire from maybe pin 5 to a solder point. When I find my diagrams I'll let you know.

I had them all printed out in a folder, but it got damp and they are pretty smudged. I have the original jpg's on a crashed HDD that I need to recover.

wow that is an old chip. I think I started chipping in about 97 or 98 and these chips were already replaced. I think they were a 16 pin pic.

All the chips I used were 4 or 5 wires, there were some that used more wires but it was more messing around with solder and all you had to do was patch the ISO anyways.
