I got mine r4i sdhc 3ds card.
But I found a question, in r4i card setting menu, when you select a game, press X, it show you an option: soft reset on and off. I have no idea what this is for. Can you give me some useful information?

if im not wrong, soft reset is to go back to the main menu of your r4 card without turning your ds off and on again

Wait, nvm, appears you're not a bot.
