KTutor is designed to be run on IBM PC and compatible computers under any available version of MS- DOS, PC-DOS or DR-DOS. In 1992, when the idea first came, I wanted to support even Hercules graphics cards which idea I fortunately gave up, but KTutor runs even now on an XT if it has a VGA graphics card.
To make life easier for those who have only slow modem Internet-access (like me), KTutor comes in 4 ZIP-archived packages. There are certain parts of the program that won't ever change, and I separated the English and Hungarian databases as you don't need both to run the software.
All you have to do is to UNZIP the files into one directory and type KTUTOR /E or KTUTOR /H, depending on which language you want to run it (English and Hungarian, respectively.)
There seem to have remained a few typing mistakes, mainly in the Japanese words. If you discover any errors, please, let me know.
The program can be used not only to practice but to learn new kanjis. If you wish to do so, probably one of the best methods is to select a range of about 50 kanjis (maybe a little fewer but definitely not more) and then do the Kanji and Jukugo reading checks until the program says there are no more new ones. (Don't type a single word; just keep hitting Enter, or 'X' if you knew the word. Read more about the "X" cheat in the manual.) Don't care if you can't write the kanjis -- just be able to recognize them without fail. Then you may wish to practice writing, but again, do until you mastered all the lexical units. Then move to the next 50. The Tests are rather for checking your existing knowledge than learning new kanjis.
