I use an acekard2.1 and Akaio1.3 but to my shock and horror I managed to download and put a virus onto my DS. The virus activated when I changed the skin to a skin called ????????. It is a really badly made skin with two not so hot girls on the upper and lower screen so I decided to change it back, when I tried this I got a purple background and red blocky writting which read guru meditation error. The same for games (excluding homebrew and homebrew software which worked but didn't save without crashing). I fixed it by reinstalling the akaio software and removing the skin. I found the skin on the acekard skin list, I can't remember its name now of hand. It could have been in japanese characters.... As far as I am aware it has had no ill effect on my PC or any long term effect on my DS. Anyone else encountered this virus and how was it able to affect my DS?
