r6299 /src/mess/drivers/x1.c: [X1]: Heavily improved the kanji reading, this fixes most games that uses that feature

afaik, just Asteka II and Hyper Olympics '84 doesn't work yet, the latter uses a different kanji reading method. And yes, this makes MESS to be the first X1 emulator to have this feature correctly implemented. smile
