Soundfont sharing threads have been created before, but have generally been short-lived. As far as ripping goes, that's pretty much the entire purpose of the forum itself, so there isn't really a point in creating one centralized ripping topic when it's possible to make more specific threads focused on different things.
However, I would recommend you check out this thread. I think you may get something out of it.

I have a link to samples from the jojo's Bizarre Adventure Arcade game that have yet to be put into a soundfont https://drive.google.com/open?id=0B88KTh5Y_FMVRGZjNHhuQTZBakk
Ah, it's okay. XD ironically enough, I got to keep a Dell Tower that I got from school, though the wires had been cut and it's missing some peices so it's just me and my dad trying to fix it up with what little we have.
