So, I'm just curious, I figured I'd ask if anyone has ever encountered this problem. I played my DS with R4 firmware v1.18 for like thirty minutes. Then later I picked it up to play again and suddenly my skin had been changed to the default skin, I use a personal skin. So I thought, this is odd... I went ahead and gone with it anyway figuring it wasn't a big deal and selected the game icon. The list was blank and nothing was showing up as if it froze, which it probably did. I popped my SD card in my computer and I find this crazy amount of random garbage. http://img121.imageshack.us/img121/5254/1r4.png <-- My SD card is only 2GB by the way http://img709.imageshack.us/img709/6452/2r4.png <-- All the garbage was in "_system_" everything else was unaffected I reformatted my SD card or whatever and put everything back in. I received the same results. Then I tried using a different SD card. This time the game list showed up, but when I selected a game nothing would happen. Well, it isn't really a big deal, I put YSmenu on there instead and it works fine. I was just curious about the problem. I've used my R4 for several years and this is the first time this has ever occurred.
