*SOLVED* MM3 on NTSC PSOne
Posted: April 28th, 2014, 1:34 pm
First off, I'd like to say my experience level is something around a medium. Not a super noob, not a professional modchip installer. And my soldering skills are only adequate. (especially considering I attempted this mod a bunch of times and got sloppy out of frustration)
I'm trying to get MM3 to boot backups on a SCPH-101 PM-41A. I'm fairly confident that all my points are continuous and not shorting. I'm using a PIC12F675 which to my knowledge is the same as the 629. Oscillator value is still programmed (and assumed valid). From what I've read, the MM3 (usa hex I might add) should be working on a PSOne.
My board version:

12F675:
When I insert a backup, I only get the Audio CD menu. Any thoughts on why this isn't working, please let me know.
Also, Old Crow works flawlessly.

bad_ad84's install diagram was the only correct one I could find for NTSC SCPH-101 PM-41.
