I bought a Chinese DS lite for my boy complete with a R4 Revolution for DS card. It played games but had many troubles with the games slot - usually not loading any cards including original games. I had the games slot replaced and original DS games play well, but it stopped allowing me to play R4 games. I had DS firmware V1.18 loaded and it showed the list of games, but did nothing when I selected one. So I replaced the firmware with Wood R4 V1.26. The interface has totally changed. It shows 3 menu items, microSD, Slot2 Card and Favourites. Selecting either microSD or Slot2 Card does nothing, and Favourites shows me an empty folder. None of my games appear. Any suggestions please - my 5 year old is soooo.... disappointed with his DS.
