So I'm trying to do something very advanced here: I want to rip music from specific roms, and convert them into midi's. The other thing I'd prefer, but it is not manditory, is that the midi file doesn't change its channel-patch mid-song. I want to do this for the following rom types:

.nes
.smc
.gba
.z64
.nds

specifically, I want to get midi rips from Kingdom Hearts 358/2 days, The Legend of Zelda Majora's Mask, Super Metroid, Earthbound, Mega Man 2, Mega Man 3, Animal Crossing Wild World, Metroid Fusion, etc.

I know that I could always check vgmusic.com,but those are either remixes, or really crappy interperetations. Iknow that the ripped music files are different formats for each, so let's start with priority #1: Vector to the Heavens (Dirge of the Fourteenth) midi, how do I do it? Man, I feel like such a noobn for asking this.

you don't. generally speaking, midis are composed, not converted

Midis work very differently from most other audio formats.
It would be extremely difficult to create a midi that is faithful to the original.

I know a whole lot about midi's, being a Finale 2010 Print Music user, and also playing with FLStudio 9 for fun. Midi's CAN be ripped, I've done it before, but not under my standards, by process of converting sound files. I still am at a 0 for ds games, I have some miniusf's, and a couple nsf's, and a butload of spc's. I tried browsing the internet, but the nly final Xion battle midi I found was a custom piano rearrangement.

there are conversion tools, but they are generally shit. hence: people compose midis 99% of the time.
