the easiest way to do this (if you have the retail cart, not digital download) is to simply eject the sd card before you start pokemon, then when it has loaded just put it back in. that way the update file is not loaded, but you can still do stuff like save pictures etc. this is what i do for animal crossing when i want to play without the update.Just so I am clear, the carts aren't actually updated, right? It's just an update file on your SD card? So presumably one could update, enjoy the online features, and then just delete the update. No? ***speaking only about the games on cartirdige, not the eStore downloads***
I can send you one. Shoot me a PM with your info. I will get you mine when I get back home/
it's nicer than just deleting the update file because then each time you want to play online you need to connect to the store to download the update again.
