I "CAN" get official update for JP. Someone wrote all official fixes. So, Current official fix/patch for JP is OK. So, Official fix/patch (for JP) isn't gone. I'm sorry for I didn't write it.... http://windows9x.no.land.to/windows98.shtml http://astra.digi2.jp/a/e/g13_084_win_98_se_1_win98_1.html http://astra.digi2.jp/a/e/g13_085_win_98_se_2_win98_2.html http://astra.digi2.jp/a/e/windows98se-hotfixes-no3.html I'll explain in different words. I want to a create a unofficial update. Because, there is no update for Japan. If some update is diverted updates for XP / 2000, I can diverted from the Japan version the same way as it. But, U891711 seems like It is the remodeling at the binary level. And, I don't know how to make the "Time Zone Update". I want to know how to create these "complicated" unofficial update. (Incidentally, I know how to create rootsupd for 9x. )
