Can anyone sort me out with a modchip?

Post by **cookie** » July 14th, 2012, 8:19 pm

A few years ago I picked up a chip programmer and some blank chips (don't have the part number to hand, I believe they were the correct ones), I tried out various .BIN files and diagrams from the internet and had little success. One chip worked (albeit erratically) for a short time and then the laser promptly died, I attribute this to the chip.

Would someone with more experience and knowledge be able to provide me with a working stealth chip for say, an SCPH-5502, along with installation diagrams? I'll cover costs via paypal.

Thanks!

I can sell you one for $15 (free postage anywhere in the world).

The chips look like this, and can be easily soldered in.
A dab of hot glue is good to hold the PCB in place.
Don't use electrical tape because the adhesive on the tape destroys the PSX PCB.

Excellent! Any reduction on that for donators?

Jokes, I'll PM you for the details.

Just an update if anyone's interested, I am short on cash so decided to dig out the old chip programmer (this one http://www.nbgelin.com/usba.htm ) and found a blank 12c508a in the same box. Performed the mod on my recently acquired SCPH-5502 (charity shop, Â£5). Swapped out the green power LED for a bright blue one too for good measure

.

Carefully read up and then followed this guide http://psx-scene.com/forums/f10/psx-diy ... post797427 using the attached M3 HEX files only the nbglin driver and software instead. Google image searched for an M3 diagram for PU-18.

The damn thing works! Pretty chuffed. Lifted a few pads with my crappy iron but they stuck down again no problem. It's booting everything I've thrown at it, hell of a lot better than using the cheat-cartridge swap solution and I get to see the good old sony intro screen again now.

I'd still recommend buying a pre-programmed chip if you don't already have the kit, though. I wasted a lot of time, chips and a playstation last time I tried this. Just got lucky tonight.

edit Looking at shadow's diagram again it's the exact same wire configuration. Must be the same hex.
