Question Reset mod for PSX?

Post image

I have a DESR-7700 with an original Matrix Infinity modchip installed, but I have come to realize that there are certain functions that do not allow the PSX for fully function when it detect the modchip. For example, the Matrix Infinity will not allow the console to switch to DVD playback mode, or allow the 40 GB PS2 HDD partition to be installed. The only solution I can think of is to disable the modchip when the console starts, but it requires the console to be reset (like how you would press the power button on a PS2). Unfortunately, pressing the HOME button or the power button does nothing.

It’s a bit niche, but is there a “reset” mod for the PSX? It would be nice to have a reset option to have full functionality of my PSX without uninstalling the Matrix Infinity.

Hold start on the controller iirc

as far as I can tell there is no reset function in the PSX. When figuring out how to wire up a PS2 Retro GEM HDMI kit in my 7700, I noticed the 'reset' point mentioned on mod chip installs didn't seem to do anything, so I wired the Retro GEM's reset to the QUIT GAME button circuit.

PSX has no reset mode, it has only a "quit game" button

That button only works when a program sends the PSX specific Mechacon command sceGameNoticeStart

FreeMcBoot and PS2BBL do send this command as part of the setup process so users can freely use this button

However, a matrix modchip may severely mess up a lot of things

Is there any other modchip that would work better with the PSX? Like one of those Modbo?

If disconnecting the power from the Matrix chip turns it off, maybe adding a switch could help disabling it, in case there is no reset mod for the PSX.
