The use of these utilities is quite easy. Making sure that the .GIF file you wish to convert to a self-executable form (either .COM or .EXE, as appropriate) is in the same directory as these tools, simply type: [For 320x200x256 .GIF files] MK320 [filename--WITHOUT any extension, for ".GIF" will be presumed] [For 640x480x256 .GIF files] MK640 [filename--WITHOUT any extension, for ".GIF" will be presumed] Happy viewing!
