I am thinking about getting a R4 for my DS Lite because of all the good things I have heard. However, I have a friend that claimed that the R4 worked flawlessly for awhile with his Nintendo DS Lite, and, all of a sudden, one day his Nintendo DS Lite was no longer functional. His Nintendo DS Lite cannot even be turned on. Did anyone experience anything like this? Has anyone experience any problem with the R4 that may affect the Nintendo DS Lite temporarily or permanently? Your advice and opinion are appreciated.
