Thunder Hoop II: Strikes Back (c) 1994 Gaelco

Driver by Manuel Abadia <manu@teleline.es>

updated by Peter Ferrie <peter.ferrie@gmail.com>

Very similar to maniacsq and biomtoy but protected :_(
The DS5002FP has up to 128 KB undumped gameplay code
pf: its presence might be a distraction, since the game runs at least partially without it
pf: but some gameplay bugs - sprite positioning is incorrect, no enemies, jump animation never completes
