These are all from the V Jump V Festival '95 video, which was digitized by dizzymoogen along with a bunch of other great stuff.
We did eventually get a TwinBee RPG in some form, but I really wish we had gotten this one, because the pixel art in this is incredible. It looks like the overhead sequences are using the same engine that was used in the first Goemon PS1 game, Ganbare Goemon: Uchuu Kaizoku Akogingu.
