Load rom errcode=-4 - Nontendo DSixl (R4) - Help

I just downloaded some games and when they run it in my ndsi xl (R4), it can't complete its loading, after that there's a warning said "load rom errcode=-4". I really did not understand what to do by reading the topics posted, thanks. Miquéias

errorcode -4 means that your current firmware does not support the game you are trying to play. you need to update your flashcart firmware. If you need further help please post as much detail about your r4 as you can. There are hundreds of different carts called r4.
