Been reading about some PSP mods.
First I was doing some reading about Go...
You can desolder the m2 slot and wire up a memory stick adapter directly, I can only see info about 128GB being tested though

Then I got distracted by mods for older models, I already have component cable for the consoles I own (I don't have Go and the dock is stupid expensive now, 3in1 charge/component 3rd party cable is hard to find).
Add some ports for an external PS2 controller mod Started me thinking about sacrificing one of my consoles for a diy tv setup that's cheaper than Go + dock.
