Hey, I received a Supercars Lite Rumble for DS and although I have read a lot oh instructions and forums I could not find answers for these questions: 1. How can I save and load a gamestate during gameplay? Is there a shortcut? 2. I know that the rumble series do not have GBA support, but I have read that small roms do work. Actually, I have one specific GB rom I want to play and the instructions suggest to put the file unconverted on the microSD card. But the file does not show up in my Game list at all. Do I need a emulator or additional software? 3. Is there a shortcut to go back to the main menu of Supercard? I want to switch between games without using the Power button. The shortcut L+R+Select+Start only reloads the game. 4. Is there a way to add REAL rumble in the game? I read that the Slot-2 device only rumbles if assigned Buttons are pressed. Is there a way to let Mario Kart rumble if I crash into a car for instance? Sorry for the many questions. Thank you for your feedback!
