I've just bought a gold tt dsi card, but when i try using it it loads up first time, goes to game screen but as soon as i choose a game it gives an error message saying ttmenu error restart dsi. when i do i find that its renamed the files on the sd card and wont start up again. is there anyway around this? i think the dsi is running 1.4E is that like the wii firmware that stopped homebrew etc?
