Magic 2 V3 Newbie help
Try the Lik-Sang/china-messiah diagrams, in addition ot the modchip.ca ones.
I still have not fully installed mine, due to the difficulty of installing on the pins of the DVD controller, and lack of anything finer than a 1mm soldering iron tip.
Nobody has proposed alternates for those pins yet, though I'm SURE they must exist. I'd even be willing to solder to the underside (though the 'S' wire supposedly is the same as Pin 2 of the Neo2, which is a top side pin, accoring to the Modchip.ca diagrams)
The modchip.ca diagrams are VERY confusing, since they overlaid the place where you solder in the BIOS points (the copper contacts at the top).
I don't really have a high degree of confidence in any of it.
