This applies to any modchip really. When I installed my wiinja at first I applied hot glue over the points before testing... bad idea. One of my connection was loose I guess and it didn't work. Trying to pick that stuff off the board is possible, but it is really hard to get it up easily. When I finally pulled up some of it, it pulled up one wire and pulled off the pad I had soldered to! Luckily you can follow the trace up to the Panasonic chip and solder directly to it. Works great now, just tried Trauma Center and Warioware on Imation 16x dvd-r burned at 8x speed. If you are going to use hot glue to cover the solder points, I highly recommend you test first!!!
