There are several possibilities. If your drive does not read games anymore, you can either try to install a new laser or replace all caps on the PCB of the GD-ROM...
Otherwise replace some resistors on the motherboard, actually is intended for VA0 to work with GD-Emu, but with this it should also be possible to install a 3,3V GD-ROM.
Here a video

"If your drive does not read games anymore, you can either try to install a new laser or replace all caps on the PCB of the GD-ROM..." or try a new Power Supply, Do a swap with a good unit or maybe a pico if you cant find a for parts console. stay away from DreamPSU

I've already tried power supply same result then I took out the gd rom and it fired up any idea of where to get the caps set for the gd rom board
