Hi all! Apologies for the noob-ness of the question but there doesn't seem to be a definitive answer to this. If there is, please be gentle with me I have 2 Nintendo DSIs (2 sons, y'see) and bought M3i Zero cards for them, which are the GMP-Z003 version. I've flashed with firmware 1.6.1, and am using Sakura 1.49 with Touchpad 4.9. The microSD cards are Kingston Class 2 2GB MicroSD. Cheap and cheerful. Whatever I do, I cannot seem to get sleep to work when I close the DS lid. The best example is New Super Mario Bros, where I get a loop of "bye bye" then "itsa me-mario", then "bye-bye", then... Repeat until hair removed! Sleep doesn't seem to work on any card: they all seem to click the sound, or whatever... I've tried slipping a piece of paper between the card and DSi to push the contacts on harder, but no joy. I must admit I thought this was the card to go for, but now it seems I should have bought something else... Damn Any help gratefully received!
