I had put lists of undumped Japanese carts (for reference)
http://mess.redump.net/dumping:games_needed
but it probably needs to be updated, now!!
The Gakken TV Boy section can be also updated with a few technical details, ranger_lennier and me chipped in a few years back and bought one of these with the 200x cart and it was shipped off to the Guru. Hopefully they will be decapped in the future.
