I have a R4i SDHC Upgrade Revolution for DS card for my Nintendo DS system and it has been working fine. All of a sudden when I turn my system on, I get a ? MENU message on the top screen and nothing else happens. Can someone please tell me why this is happening and what I can do about it without having to format the card and erasing all my games or purchasing another card. If so, how can I download more games. Would greatly appreciate a quick, accurate response. DebbieB
put micro sd card in pc reader back up to pc first. download new R4 kernel latest from here http://www.linfoxdomain.com/nintendo/ds/ unfortunately the are over 35 R4 cards needing 35 different types of firmware hope you can find the right one, download having winrar installed right click on download extract here ( before you do this drag the downloaded file to micro sd) once extracted you can delete the winrar file. good luck you'll need it when you get the chance get well away from anything with R4 on it
