Hi there, I'm trying to install an mm3 modchip on my jap ps1 scph1000.

I've tried to follow this: https://quade.co/ps1-modchip-guide/mm3/pu-7/

And this:

With no luck, doesn't read jap copies nor us original disks.

I'm kind of stuck at this stage...

Thanks to anyone who would help

If we assume your soldering was done right and the code was flashed correctly to the PIC, it could be anything from incorrect install guide images to bad code on the chip. The most common being that the install image that told you where to solder doesn't align with the pinouts and logic on the PIC.

Kippykip made a proper guide collection. Just use that instead and be done with it http://psxdev.net/downloads/modchip_install/MM3.ZIP

Thank you so much for your reply.

I'll test that asap and I'll post back the results!

Hi there, thanks to your guide it's all working fine now! Thanks again!
