The confusing thing is that VGM_play (above) is different from VGMPlay (the standalone application Valleybell made). I believe Valleybell was referring to the former when they mentioned "vgm2rom", although I could be wrong and VB was referring to some other tool that they had personally created.
of course, if you have some evidence (or very strong belief) that this isn't what you were looking for, I apologize, and in such a situation must admit my own confusion about how such a thing could have disappeared (I guess you could always ask VB).

Ah thank you, that is indeed what I was looking for. It'd been so long since I used it I forgot the name, and when I saw the vgm2rom reference I assumed that must be it.
