I have searched everywhere including these forums and have seen all the "noobs"; which does include me; posting there stuck in loading screen problems with these R4 clones. My sister gave me an older used ds (not lite) and I thought my 4 year old boy would love it. Had heard of the R4 cards and googled to buy one and the first site I saw was D**LEXTR**E. R4 III upgrade revolution for ds. Ordered it and three weeks later it is here. The site said they stopped giving out the discs and when mine arrived it had a disc. So I tried that, nothing. I tried the site that the box said www.r4dsl.net, nothing. I have tried different language ones, I have tried ones from different sites that claim to be the cloned firmware. Nothing. Stuck in loading screen. I am far and away not very good with all this stuff, but I can read and can operate a computer and have done a few other things like with a wii that may constitute a knowledge with some of this stuff. Google is pretty deep and informative. However, I cant get this thing to work and I am wondering if this card is any good at all. I bought a 4GB san disk micro sdhc card from best buy thinking a reputible place would sell good cards. Is the micro sd card bad, is the R4 III clone card bad? Or I am just an idiot that is missing some detail. I have put more system, moonshl, ds mshl nds, ds menu.dat files on this thing than I care to mention. Everytime I try a new one should I be deleting the old one or just overwriting. Everytime Ive downloaded these files the ds menu one comes up and says its a windows media file. Is that correct? Am I deleting off the sd card wrong everytime. My boy is sick this week and home all day and looking for some mario action on his new/used ds. Please help me give that too him and please be gentle with my dope azz. Thanks in advance for any help.
