guys, My son has an r4 ultra card that has been working in his DS lite. I have tried the same card in his new DSI XL running 1.4.5 and it throws up the "error has occurred" message. From what I understand I just need to update the firmware on the r4 using his DS lite. Trouble is I am not sure of the process of upgrading the firmware and which file I am supposed to use. The card just says "r4 ultra" on it. Any Ideas would be highly appreciated Thanks ! if it makes a difference , this card is black and grey. the website listed on the card is r4ultra.com anyone ?
