i have a yugioh world tourny 2008.nds game i put it on an acekard, i got a save file from gamefaqs and it was in .duc format i used a program called max2sc.exe to convert it to 512kb .sav format and put it on the acekard in the same file directory as the game on the acekard so now i have the game in .nds and the save file as .nds.sav (according to the acekard)(on the computer it shows as .sav) but when i play the game there is only new game available. is there some thing extra you have to do to the save file to make it work on the acekard? also when there was no save file with the game , i played the game and made a new save file, i checked that save file and it was exactly the same size and name as my save file, so i dont know what is the difference. can anyone help??
