DID NINTENDO HACK MY DSI AND PLANT AN ERROR MESSAGE TELLING ME TO SWITCH OFF MY DSI? IF SO IS IT FIXABLE? PLEASE HELP...........................
Yes they did, and no it isn't... is what I would like to say, but sounds like you've upgraded to 1.4 Firmware. So to help us to help you, tell us the EXACT model of your card, oh and whilst you are at it, fix your capslock.
probably you got the DSI update that blocks flashcarts. You will need to update your flashcart using a DS, or if it is not updatable, buy a different flashcart. Additionally, please refrain from posting in all caps, as it is considered rude.
