PS1/PSone Mod Chips

Ok some good news on this - Link.

The six wire install method is working on the PSone, but that means a boot disc has to be used for import games. But now that the console is chipped, this boot disc is simply burned to a cd-r.

I'll continue searching for an 8-wire install method for the PSone (SCPH-102), but at least it's progress.

If you're in a hurry to get my 2 chips off your hands let me know, otherwise I'm ok with waiting a bit, possibly have enough time to pick up a console as well. :P

You don't need an install is that right? If so, you free to pick em up whnever really. I actually posted another chip there last week, so if you want I can do that too.

Well I see a 7 wire install for that model, what advantage that has over 6 wire I've no idea. Accurate info simply doesn't exist anymore it seems, so unless you can find that out I'll have to install it & see what can/can't be done. I would imagine it's direct multi-region booting, but can't confirm that for ya yet.

Would it be that you got outdated modchips? I know there's different versions and later ones let you play some games that had extra mod chip security.

Found that, it might be of some use although you might have a different chip from what they sell.

Edit: Seems some chips are region specific as well.

Nope, the MM3 & ONEchip are the latest chips, it's the PSone that's the problem. It has extra security that checks the display mode as well as the region coding.

This place has installation diagrams for different chips as well:

Edit seems you have to register to look at them.

I have them, it's where I got the chips

To use the MM3 with the PSone, 6 wires are only used, anything more and it doesn't work. See this post. The SCPH-5xxx may very well work perfectly with the 7 wire method, I just can't confirm that as info is innaccurate/scare, & I'd need the exact model of your PS1 too.

Hmm, so when you do the 8 wire installation it somehow breaks the playstation. Sounds like an absolute nightmare. Can't tell you the exact model since it's in o1s1ns at the moment. I did find a website with a load of installation documents for the onechip for all different models if it's any use? they are at the bottom of the page and hosted on a filesharing site, the password to open them is displayed in the text on the right when you open the rar file. Hope it's some use:

Nope, ONEchip has different soldering points. It doesn't break the Playstation, I broke mine by cracking two little resistors. There doesn't exist an 8 wire method for the MM3 for the PSone, simple as.

o1s1n when you get a chance later on, let me know the model of Retr0's PS1 & I'll check what I can do for him, he must be worn out having to get up to use that swap disc the poor fella :rolleyes::D

It does get really annoying after a while to be honest. It's even worse with multi disc games that don't save at the disc change and do a seperate check when you change disc so you only get to play the first disc. Happened to me with koudelka. Ended up buying it for quite a bit of money and then hating the game!

Hence why chips are better. It's unfortunate that NTSC images must be patched with this chip on a PSone, but such is life. It takes a few minutes & then the game will direct boot, no boot disc needed at all.

Or you can use the boot disc if you don't want to patch the image.

Or you can order ONEchip's.

We'll just have to wait till o1s1n tells us what model your PS1 is.

Ok for anyone that's interested, this is the patching procedure for NTSC games if your using an MM3 on a PSone (SCPH-102)

You can try your own methods, but I find this one failrly bulletproof. This doesn't defeat the copy protection on PSX games, only modifies the region information so it's safe for posting.

Ok I'll keep this simple, as it is very simple. Three different tools, three different folders. Lets begin in number 1



Inside folder one there is the first tool called patch-it. There's also a readme file, & the three different region files the tool needs. I've also placed my test image in here (bin & cue format).



Run patch-it, navigate to where your image is stored (it must be the same directory as the programe), click the pal region & hit patch.





Now that's it, the region info has been patched. Unfortunately, the display protection hasn't been patched, meaning the image just rolls when you load it (it does on the PSone lcd screen anyway, I presume a tv is the same).

Therefore we need to use the two other tools to sort that. Go into folder 2 now & load pal4u.

Navigate the programe to where yor image is (it should still be in folder 1 from the first tool), & hit 'find seq's'





Once that's complete, the programme will have found the necessary changes & will ask you where to save these changes in the formate of a patch file. Save it in folder 1 alongside your image, for simplicity sake.

Now, final step. Go into folder 3, which has the tool which will apply the patch we just created to the image.



Load up p4upatch, tell it where the patch you made is, & tell it where the image is (both should be in folder 1)



Press start, and when done you'll get one of two results. Either a success or a fail. DO NOT WORRY if it's a fail, it just means any one of the nine patch steps were already done in the image prior to any of your work.



That's it your done. Go back to folder 1 now & burn the image. Here's how folder 1 should look at the end, you can see the image files, & the p4u patch.
