I have a DSi XL. How is the compatibility (english games only) with the latest firmware and kernel? Any good (or popular) games that have problems? How does the rom compatibility compares to Acekard 2i? One of the EZ5i features i like is the in game walkthrough. Does it work well with all games? Is it easy to set up and use? How about the RTS feature? Does it still have bugs with some games, with the latest fw/kernel?
