thanks for your informative reply. The DAT i am using with offlline list is DS_Europe_(En)_ADVANsCEne, i have just downloaded the other one you directed to and the game titles were no longer red (missing), however i could not select nor add them to the selecter, it is currently updating, seems to be downloading a hell of a lot of .png files, these were already present so i am not sure wheter its downloading missing or just doing the lot again,,hopefully after the missing ones will show up as usable, like i said, there is nothing wrong with the actual roms themselves...i dont quite understand what you were suggesting i do, hand edit EVERY one that is showing as missing ?..i would rather just have the program bulk verify them as not missing so that i could then add them to the selecter.
