Adjusting PS1 Laser to Read Original and Burned Games

Going over how I fixed disc reading issues with an original Playstation that I installed a modchip in. It had trouble reading burned games after installing the chip, but read originals just fine.
WARNING: Be very careful when adjusting the laser intensity. Make very small changes to the pot and be sure to check the resistance values with a multimeter as you go along. You risk permanently damaging your laser by doing this.
