Hi.
I read your forum about editing the main.dol. I can't edit the programming to NSMBw yet. BUT I CAN ADD LEVELS!!! You don't need reprogramming: You need to edit the world map. If you want a 01-07.arc working in game, you need to edit CS_W1.arc and RouteInfo.arc! Use brawlbox v0.67b or later for CS_W1.arc. And use Ctools, Notepad, and Microsoft Excel for RouteInfo.arc. Contact me if you want more info.
