I just got my LCD kit from him yesterday, it was about 10 days from him somewhere in Europe to me in USA. GG mod is a bit harder than Lynx mod because some of the parts to be removed is much smaller.
Lost 2 of the SMD transistors but aside the CFL, LCD, 2 large caps, and 2 fuses all the little parts could easily fit on a microSD. You will need a small tip soldering iron or a decent desoldering station to remove those without damaging PCB. The solder spots where the 2 fuses were removed needs to be cleaned and flat so the LCD mod can slide in.
Yes it plays SMS games off Everdrive GG or via SMS converter and
plays GG games without shrinking a lot like the old RGB mod.
Total time was around 2 hours with lots of distraction to TV. I could probably have done most of it in 70-90 minutes with the TV turned off.
The only mod to the GG case is to remove the screw post on the front shell. Just one. Additional mod needed if you want to install VGA port.
Another advice: soldering wires on the original LCD connector is also challenging. I would suggest something really small like 30 wires (like kynar). I used 24 and they were a little fat and almost touching next pad.
