Is there any special way GDI files should be saved? I'll give an example how the files look on my harddrive. I was just to lazy to dump them myself.) I have no clue what could be the problem. (By the way I do own an original Dreamcast with a great collection of games - just to prevent any bad thoughts towards me downloading games -). Since the goal of TOSEC is to preserve the best possible copies of original games, these sets shouldn't be bad dumps. I downloaded several files from a TOSEC set. Additionally I read GDI files can be converted into CHD files and I think this converting process doesn't produce a romset. Actually I don't think CHD files (the ones for Dreamcast!) require additional romsets, since Dreamcast games are just this - a disc. I think I'll be concentrating on GDI files, since CHD seem even more complicated.
