I'm trying to open some files from a PS1 game, but all the files are in .nsf format.
I found out on some site that I could open .nsf files in Lotus Notes, but it didn't work.
Not sure if this helps, but there's also a smaller .nsd file for each .nsf file.

Are you trying to play the .nsf files?
Zophar's Domain has a good list of programs that will play .nsf files.

As for the .nsd file, I don't know what that could be.
Here's the page from FILExt.com showing the possibilities if you need it:

I don't necessarily want to play the .nsf files. All the game data is packed in separate .nsf files it seems.

It looks like this:

And in every folder it looks like this:

If it's possible, I'd like to rip textures, sound effects, MIDI music, and even 3D models.

hmm i think we are not talking about the same thing then .nfs are nes sound files which can be played using winamp and foobar (via foo_gep). you are talking about nfs files in a ps1 cd, so you might want to look for Playstation cd data extraction. which game are you trying to extract data from?
