For my Gamecube portable would it be more convenient for the user to have the standard av out plug that is on the gamecube when you buy it or should i have the Composite jacks of Yellow white and red
Use the original connector if you're good at soldering and can relocate it, the nintendo a/v cables are really average, most people have at least 5 or 6 of them lying around
If you have space to spare on your portable and aren't the best at soldering, use the rca jacks.
