+ Moero Pro Yakyuu Homerun - (c) 1988 Jaleco
+ Dynamic Shooting - (c) 1988 Jaleco
+ Driver by Tomasz Slanina
+
+ *weird* hardware - based on NES version
+ (gfx bank changed in the middle of screen,
+ sprites in NES format etc)
+
+Todo :
+ - voice ( unemulated D7756C )
+ - controls/dips
+ - better emulation of gfx bank switching
+ - is there 2 player mode ?
