I don't think those games (or any sms games) have more than one language programmed into them...
They must. If I play western games on my PAL MS they naturally display in English; playing the exact same cart through a Japanese MS via an adapter makes them display Japanese text and in some cases an alternate title screen.
1. Use Kega to load th egame of your choice 2. Set system to Japanese and reset (Tab). Notice the Japanese title screen. 3. File -> Game Genie/PAR and press the "CodeFinder" button and choose "State" mode. Choose "On" (since you want Japaneseness at the end). 4. Set to not Japanese and reset. Notice the export title screen. 5. Back to the cheat finder and choose "Changed"
This got me the answer first time for one of the games in your list. If not, repeat until the list narrows down. It's much the same as using the cheat finder in the PAR itself.
