Hi, I did a search through the forum and didn't find anything helpful about my problem. I have a R4i sdhc Dual core ( also referred to as white on product comparison on website r4isdhc.com) It ran fine most games fine, until I tried a more recent one. I went to their website and downloaded files for version 1.42, which I thought was the most recent. After that, I ran the "patch" (or what I presume was the patch acording to the instructions they gave) and it upgraded fine, in a black screen like the old MSDOS. After it ended it was needed to restart the console, which turned off by itself. I turned it on and no longer was there the Sponge Bob icon, instead it said there wasn't any DS game cartridge in. I thought the problem might have been the version on my DSi wasn't supported by the cards new version so i updated it through the System managment or whatever. Still not working. I have lost hope of finding the answer on my own, so here I am posting about it. Any help is apreciated.
