I'm trying to install a Modbo 4.0 v1.99 chip on my PS2 Slim SCPH-90004 8D GH-072-42.
I'm using this diagram: http://www.brisbane-mods-brisbane-mo...-GH-072-42.jpg
However, I'm confused about where I should connect the 3.3V and GND from the chip to the PS2. The diagram shows I should connect VCC to a piece on the board with "202" on it at the location PS14. However, on my PS2 that area looks a bit different and on the place where "202" should be there is a piece with "50" on it.
Should I connect the GND point on the chip to both GND points on the PS2 as indicated by the diagram?
Sorry if any of the above sounded confusing, I can take a picture if necessary. I don't know much about the technical aspects I just know how to solder a little bit .
