I downloaded a cheat database for itouch ds and installed it correctly. ... i replaced the cheat.db in the itouch folder with the 6.15Mb cheat.db file i downloaded. then i set the cheat directory to the proper folder. the cheat codes in the database work for all the games i have except for Final Fantasy IV (U). itouch DS displays the cheat codes for FFIV(U), but after i check the codes i want activated, and then press A to activate them, the software declares "There are no cheat codes for this game !". why is this happening? and how can this be solved? can anyone please help..
