My nephew (don't like him anymore), once have downloaded an update for 3DS, but I manage to stop him before he had a chance to apply it. But now he finally have finished what he had started. Now I have 4.5 firmware so my DSone wont boot even with newest software (tried to update it with firmware writter). I never had any other flashcard, so I do not know what to choose. I can buy Dstwo, but its kinda pricey, good altgouht. R4i Gold can last long, and its really sheap, but I'm not sure about its funcionality. What can I loose, beside quicksaving, if I'll buy this one? Or there is any more alternatives? Moreover I dont have any other DS's around, so I need a card that can lauch on 4.5 out of the box, or have a firmware writter alongside it.
