VB is right there with NGPC, the libraries are just too small, as are the user bases. Krikzz would never sell enough to make the investment practical. The VB homebrews consist of largely unfinished SNES ports, which look terrible in red only, and others which are very simplistic. Very few actually incorporate 3D the way the official releases did.
I've played VB numerous times, it's a great novelty to own, but I personally never would because I find it too straining on my eyes. Same feeling I had when I played my friend's in high school 20 years earlier. GBA (if completed) will make Krikzz far more money.
