Basically I have 2 DS lite and a CycloDS as well as a R4 SDHC. My CycloDS and R4 SDHC work fine on one of my DS lite but not another. Both are able to load official game carts though, so I ruled out the possibility that the one not able to load flash carts is spoilt. Anyone has any idea how to rectify this situation? Any help is appreciated!
