There's no tool for hacking SMB1 music, or at least not yet. You'll have to edit the music code directly in a hex editor. There should be a document or two on the site about how to do it.
1. The game crashes after entering the pipe on World 1-2 in my hack and how do I fix that?
Which ROM are you using? The reason I ask is because there is a bad dump of SMB1 floating around for decades. This dump lacks the title screen, an IIRC, pressing Select makes you swim in the air.You probably shouldn't work with that ROM.
2. Is there any tool for hacking SMB Music?
Yes. Me.
I'm using a rom that patched the spiny egg patch.I made that IPS file with the normal file I dumped.
What I mean is the "normal file" you mentioned. Does it have the title screen?
SMB1: Escaping the Underwater Dungeon
Did you read the article?It identifies several sectors of bad data in flawed SMB1 ROM dumps, and how those sectors should be rewritten.
