What to do with a game with multiple names

[Retro64]

Recently I had ripped Diskun for the game Janken Disk Jo https://www.spriters-resource.com/nes/jankendiskjojpn/
However after the game was accepted I realized that

1. The game is actually called Janken Disk Jō not Janken Disk Jo
   
2. It also has another name as well being Janken Disk Shiro
   

My question is should we keep the name the way it is, add the accent mark, or add both names with a slash in between?
