so I'm pretty new to "complete romhacking". I did some translations but never released them. Wanted to do a mega man 1 hack.

1. How to do some basic weapon ASM hacks, like some MM2 hacks have?
I want:
- larger travel distance for Cutman's weapon
- to make the Gutsman's weapon work without rocks near you
- to be able to remotely detonate Bombman's bombs instead of them exploding after a given time
- for Iceman's weapon to be like in Claw (MM3GB Screw Crusher)
- Fireman's weapon not shielding you, only firing the projectile
- Elecman's weapon clearing the screen
- Magnet Beam to be Claw's Jump Chip

2. How to do music hacking for Mega Man 1?
Found some mega man 2 music hacking stuff, heard that mega man 1's music engine is almost the same except 12 bytes. but, where are the song locations in the rom?

All of these can be found in 1 single document.

You can probably learn 6502 ASM even the basic levels through Romhacking dot net. I've been hacking Megaman 1 for years but I am still learning to code certain aspects.

Good luck!

I'm sad that there exist a disassembly for MegaMan 1, but to this day still no disassembly for any other MegaMan games.

Don't you guys realize how many more ambitious hacks we would get if games like MM2, MM3 and MM4 would get disassemblies? Our hacking scene would finally be on par with the Sonic hacking scene.
We would finally get more hacks with changed music, new objects and the like. Changing music in a MegaMan game would FINALLY become a MegaMan hacking standard!

Seriously, just imagine all the posibilities. I'm still surprised why everyone would rather painly hex edit the ASM changes, if ASM changes can be done so much easier through disassemblies. Especially split disassemblies. Just imagine:
*every object has it's own sprite file, which later on gets assembled when you build the ROM
*porting enemies from other MegaMan games...on the fly!
*every music and sound has its own file, so music hacking can be as easy as in Sonic 1, which is literally just "convert a MIDI into the game's music format through a simple executable"
*just imagine what complex objects could be implemented when you ASM hack through a disassembly instead of painful hex editing.

Seriously, it just pains me that MegaMan hacking is so far behind, it's not even funny.
And the worst: If I was to make the best disassembly ever of the MegaMan game that gets hacked most popularily, it still wont get used, because not even the hackers themselves want to move forward, and that's just sad.

@trinitronity puresabe made a mm1-mm2 midi to music engine converter but it's kinda hard to use.

oh and most assemblers for NES are dos based and I have a 64-bit PC sadly.

You must DOS-box if you know how to do it to open DOS programs.
