Ok, i have downloaded the Diddy kong racing ROM and have been trying to get it too work on my supercard SD. Like people have explained to me i, installed the new firmware 1.7 onto my DS and i downloaded both Supercard V2.56 and V2.58 for SD. I even tried Supercard V2.58 for Micro SD. So... obviously none of these worked even though i tried all the different combinations of DMA or trim on/off etc... Ive even updates the new patch thats supposed to help me play the game. Is there ANYTHING at all that you can think of that will help me be able to get this game to work??. I have the supercard SD with bobba fett sticker on the front plus the superkey. Please i really needed help, i never thought id do it but i have spent at least 4 hours trying to get this too work. Thanks.
