I was thinking I would like to see if I could dust some rust off my Japanese and try and translate a game for the NGPC, maybe Rockman as there's not much there.

I know there are some tools around, but not really familiar with the how to on that stuff anymore to where I can extract the Japanese script from the game so I can get started on it.

20 years back I used to do this using an old DOS hex editing tool on Windows emulators from Japan for the NES among a few things and did pretty well tweaking menus but this is a bit more complicated.
