Processing. Do not power off! it's a save error issue i tried 3 defective acekard 2 with normal kernel and give Processing. Do not power off! error, always S1 flash. But i tried to load on memory only akmenu4.nds and not the __ak2 directory, after i can load and play games with that already got .sav files of 512kb on memory , but cannot load new games without sav file. i think that Processing. Do not power off! cannot create the save file correctly. if you make a __ak2 dir empty, it will create a lastsave.ini file with 0 size. i think it stop there. just to say that acekard 2 with " Processing. Do not power off! " are playbable if you load only the akmenu4.nds and games with save file . the problem is without another flashcard 2, cannot create save file... but maybe can download them ? i dunno Hope this works for some people that cannot replace it.
