You may need to update the firmware on the R4. The DSi may have blocked use of the flashcards, for whatever version you're on, on the DSi.
Yeah, check the URL on the packaging. But chances are you can't upgrade it since most r4 clone can't be flashed. Try ordering an acekard 2i, check slickgate.com if you don't know which site is reliable.
you updated by wifi.... set your date back a year is a temporary fix for now. thats all the info i got so far.
that wont work at all. your on about the date error it brings up now and then not data. the card has been blocked by update as you say but you cant roll the date back, its either blocked or has wrong f/w
Could we have more details please? 1. Which R4 card are you using? Please give the website of the manufacturer, it should be on the box or even on the cart itself. Does it say "R4i" or just "R4"? R4is work on DSis, "R4"s usually don't. 2. What Firmware is your DSi running?
