Perception IME and Polymorph VM have the following project repositories,
http://code.google.com/p/perception-ime/
http://code.google.com/p/polymorph/
With the following items,
Perception.Library,
Japanese.Language, Chinese.Language, Korean.Language drivers
Japanese Keymap for the jp106 keyboard layout,
I still need to confirm the Keymap for AmigaOS4.x (and compile a version for AROS)
Additional materials have been Wiki'd on the Project sites as well.
Any feedback positive or negative will be appreciated.
