I have an EZ Flash IV, and sometimes I get these .cla files that get on my SD card's "saver" folder. I cannot delete them either because it says "they are not found". This particular .cla file is named: "Mario -.cla". I am assuming it is from one of these two files I have on my EZ Flash IV's SD: Mario - Classic NES - Super Mario Bros. Mario - Mario Kart - Super Circuit I believe I used to get these .cla files for my Super Advance Mario games, but I renamed them all to MSMAx and I don't see them anymore. Also, do other Mario games like the Classic NES game and Mario Kart have to have a 8:3 file name? The Classic NES - Mario is IPS patched.
