DS lite with R4 V1.4.! www.r4i-sdhc.com , kingston micro 8gb , I had no problems with menu or several games 2 months ago, then the memory card fried and I finally got a new one. Uploaded the new kernals with all firmware and when the card is in the DS , top screen says Moonshell Ver 2.01+1 stable booting extension memory not found bottom screen japanese/chinese words Was ROM file of a correct DLDI patch started reformat media and try again please try with different media from another media function Tried the paper/card trick between cartidge, blowing/sneezing on contacts, formatting memory card and reloading firmware/kernals, tried only loading moonshell 2.1 stablechildzwai edition along with r4. Not sure what to try next. Thanks!
