Ahai! Welcome!

Hello everyone! Today I recovered a PS one but I noticed that the optical unit only reads burned games but not the original ones. The excellent group is the KMS 440BAM. How many ohms should I calibrate it to? I read on the net that for a good reading it should not exceed 680 Ohms. Could someone give...

Thank you very much for everything!
Would the exploitable game disc be like the Gameshark CD? Does it allow you to load a bootloader onto the memory card?

If both are available, I have no problem.

Hello everyone.
I have a PS one SCPH-102 PM-41 Board.
Would it be possible to use it as a Dev Console with for example a MemCard Pro?
Are there other methods?
I await your clarifications.
