dude... I found an AWESOME game (not really a game, but comes in a real ds cartridge) that's from japan, and uses the touch screen to recognize hiragana, katakana, english letters, and kanji. It is just under 128 megs after trimming. It's called Kanji Sonomama Rakubiki Jiten. Try to find it somewhere. I obviously can't post a link since it isn't homebrew, but I highly reccomend it.
Kanji Sonomama Rakubiki Jiten would be a JAP-EN, EN-JAP dictionary, for those who dont know.
i'll add this to my review list.
