Found the problem. Burned to dvd-r and not cd-r. Works now!

Unfortunately, no - the chip with multiple "dino modes" was Stealth 2.8a, and that didn't save it, so you had to hold down the RESET switch for 3 seconds to switch mode every time you turned the console on. Mayumi 2.1 (the one that ran on the PIC16F84) has the current operating mode store...

None of the old chips managed 100% stealth on PU-7 and PU-8. Mayumi 2.x and the MM2.x series chips were pretty good, but they all used the same basic approach that timed the boot process and used the x1/x2 line from the CD controller to work out where in the boot process the console was. This was s...

PU-8 boards aren't supported by MM3 or Mayumi 4. Those chips are normally recommended. I believe "Stealth 2.8" (or similar) is the next best thing out of the classic modchips. If you ditch the PIC and get an Arduino, try PsNee! It supports stealth on PU-8. http://www.psxdev.net/forum/view...

Hi! I just bought a Ps1 SCPH-1002(PU8) last weekend. I'm looking to mod the ps1 with a modchip. I have bought a K150 programmer, 2x PIC12C508A, 2x PIC12F508(I also bought a socket for the pic so I can switch the chip easy if i need). Which chip/program is the "best" for my system/board?(MM...
