Man I get so confused when people have extensions shown for some things but not others. Your text files all don't have extensions so that's easy to see, but your 'custom.exe' doesn't have an extension while your 'th128.exe' does, as well as 'vpatch.exe'. I'm going to guess that you don't need the extension for exe files, so try renaming 'th128.exe' to just 'th128' and try again.
