questions about dvd region x, and action replay 2

[sp4m]

Hi!

I have a few easy questions...

does anyone know if dvd region x works on a PAL v7??? i get very confused when reading about this...

what addons does Action Replay 2 V2 support? It says USB keybords? how does this work? can i configure any button on the keybord to "emulate" the buttons on a ordinare PS2 controller, and make that work with EVERY game? what about USB mouse?

Does AR2 have any support for ordinary PC USB network cards? If so is the case, can i copy files to my PC from the memory card with this?

And another thing... Does the Expansion Memory Card 16M (for PS2™) work just like a ordinary memory card? when i plugged it in, and a 8mb memory card of corse, does it work like it just to work, just with 24mb instead of 8mb?

So, the final question... Where do i buy this items cheapest? i live in sweden so the store must chip them here... the cheapest iv'e found is http://www.lik-sang.com (AR2 $35, DVDRX $13, Expansion 16Mb $17)

PLEASE answear as many questions as posible... i know how anoying it is when someone asks the same thing twice...)

THNX!
