I found my old Nintendo today and wanted to play again. Unfortunately my R4 card doesn't work anymore… Does anyone have an idea how I can get it working again?
Take it out, blow on the card, blow into the card slot and then slowly insert the r4 card. With much emotion
Aw, nostalgia!
Didn't grow up with Fortnite and Deutschrap
The card was probably blocked with a firmware update from Nintendo. The only help is to update the firmware of the R4 card. To do this, take out the SD card of the R4 card and insert it into the PC. Then you go to the website of your card and download the latest firmware, you throw it on the SD card. Then insert the SD card back into the DSi and with a little luck it will work again.
Please don't call your DS Nintendo.
