I downloaded the latest cheat file (Acekard 2 Official v4.17 *Update File*) and unzipped it. I opened my SD, and replaced AK2menu.nds in the root, as well as put the "cheat.xml and cheat.dat" file in the "ak2/cheats" folder. I turned on my DS after putting the SD card back into AK2 and AK2 into the DS. I went to "DQ5", pressed start and went to cheats. It said, "No Cheats in cheat database" followed by a window. In that window, I pressed Y to change the cheat file to ".dat" and then pressed rebuild, but I get an error message saying it couldn't find any cheats. I did the same thing except I changed the cheat file to ".xml", and it said the same thing: it couldn't find any cheats. Any help would be awesome. I'm really new at this stuff.
