Hello.
I am afraid that remastering puppy is becoming more and more difficult.
So far I have made Japanized ISOs of tahrpup, xenialpup and bionicpup64 with remasterpup2.
tahrpup ... No problem
xenialpup ... At first boot, /root/.xinitrc is reset. It is necessary to avoid this in order to run Japanese input system.
bionicpup64 ... The same as xenialpup. And /etc/keymap is not reflected when xorg.conf is generated. A workaround is necessary.
fossapup64 ... At first boot, PuppyPin is overwritten. A workaround is necessary. And something is wrong with keyboard setting. The remastered ISO is incomplete.
After all, as for fossapup64, I have made an Japanized ISO by making use of a new adrv containing files related to Japanese, renaming the original adrv as ydrv. /etc/keymap is not reflected. So a workaround is necessary.
(Edit: To generate xorg.conf with a setting for the Japanese keyboard layout, I edited xorg-autoconf.)
Also it is necessary to avoid PuppyPin being overwritten. I got a hint from the post:

In another thread, localization of puppy is discussed. However, as I stated above, there are changes in specifications of puppy, which make it difficult to localize puppy.
