Well some more bad news for you now mate....sorry!
The action replay/Gameshark discs DO NOT work with version 7 machines. They somehow know that the swap has taken place...regardless if it's a no solder mod, or neo2.2 and refuse to boot.
The only way to boot them is to use the swap magic 2 discs...which not only cost you more money, but also don't work with many games out there. Trust me because i've been using the swap magic 2/no solder combination in my version 7 As it's only a backup machine at the moment. ....Ie, i've got a v5 no swap combination as well
The best thing i can suggest is to speak to them and ask them to change you're order to a messiah 2. It's only gonna end up costing you the same as buying both the no solder and the swap magic discs anyway.
