I was experimenting and i get a little surprise, i discovered a little a hidden .nds file on a homebrew (i didnt know what is this file for), the file is a recreation of a DS Lite menu and you can find the download play, the pictochat and the settins, AND ALL WORK, except the settings because i dont think that a little .nds file in a dsi flashcart (obviously on ds mode) could change a setting in the DSi. But today i put mario kart ON AN OLD DS LITE, next i enter to the wifi settings and i select the transfer tool. Now, in my dsi, i execute the .nds file, select download play and i downloaded the transfer tool and... THE WIFI SETTINGS OF THE DS LITE HAD BEEN TRANSFERED TO MY DSI; including the access points and the wifi id so... A HOMEBREW ON SUPERCARD DS ONEi COULD CHANGE THE DSi SETTINGS!!! So, why we cant use this method to transfer a hack to the dsi memory?
