Tip: If you make a change to your ROM that you regret, just go to File > Restore > Restore ROM to Previous State in the menu. From there, you can select a restore point and revert your ROM to a previous state.
Is it hard to add (GB) in submission name? I got confused, does that mean nobody else will? Even wikipedia page about Game Boy game has (Game Boy) in article name when specifically talking about Game Boy game. Maybe roman vs. arabic numbering isn't a big difference. They both represent the same number, so how can you not confuse them?
Games for GB have Roman numeration and NES titles Arabic numbers regardless of where they were released. Outside of Japan, games for stationary consoles have Roman numbers in-game and their Japanese counterparts have subtitles, besides the first one. Every GB game in Japan has 'World' before the number and common sense would imply that so should their Western counterparts. In order to avoid confusion, all the Western games for stationary consoles are given Arabic numbers, no matter if they were released before Mega Man 8 (the first Classic game not to have an Americanized logo) or not, whereas GB games have Roman numerization.
