yea should be fine to mod with argon..if its a d2c board, id still use the 13 + 4 wire install as its rock solid compared to the 9 wire installs....i only ever connect the 13 wires though as region free isnt something id recommend unless you cant wait for pal versions of games to come out...and vice versa for you with it being a ntsc-u wii.
as for firmware updates...updateing what .?? wii .? argon.?
only update your wii with an ntsc-u game. never use a pal update.
if its the argon your talking about as long as you use the 13 wire method then 1.8 is rock solid and probably will not need an update...but if you decide other wise you need an injectus programmer for the argon....
no spin on drive ..the wii is on 3.2u and i install it to the diagram as done before on others ..this is the first usa ive done
sounds more like a short or bad connection, won't have anything to do with the region, a usa drive is exactly the same as a pal drive the difference is the console, the console sets the region.
just taken off the 4 extra wires now i get spin up ..but not playing pal backups but plays usa original heads gone ...checking wires now
could it be the argon fw not sure what fw it as on it ...has a pink dot
i dont think it will play pal backups once the 4 region free wires have been removed...do you have a usa backup of any game.?
the install is exactley the same apart from the 4 extra wires..... P Q O and SX for region free for usa.....
