After doing some googling and searching the forums I've decided to post my ignorance on the forum. If this has been answered before I apologize. I have been enjoying my Acekard for a month now playing DS games. I decided to buy the EZFlash V 3in1 to have the rumble feature and the extended memory for the opera browser and play GBA games. I have AKAIO 1.4 installed and 4.15 firmware. I have not tried playing GBA games yet but will soon. I am trying to use the rumble feature with a DS game and have had no luck. The game I am trying to use the rumble on is Metroid Prime Pinball. Any help will be greatly appreciated. Also I have the OsUp software to update the card and the OS. Should I not use this anymore or use it just to update the firmware and not the OS. What does the WiFi update on the AKAIO update? Should I be using Bliss? Thanks in advance. This is my first post. Really love the site. I have learned alot searching the site.
