FBA has another new game: Grasspin by Zilec Electronics / Jaleco (c) 1983!!
Whilst fixing some music issues in the game Blueprint, I realized there was a game missing from the driver, all that was needed to add it was some simple modifications to the graphics banking and dipswitch handling. As as side-effect of these new changes, Saturn (romset: saturnzi, same driver) scrolls a lot smoother, too. Success!!
