+Controls + Dipswitches *done* - stephh
+Verify Z80 program banking
+Fix Priority Problems *done* - Pierpaolo Prazzoli
+Merge with gcpinbal.c (and clean up gcpinbal.c)
+
+
+Note, a bug in the program code causes the OKI to be reset on the very
+first coin inserted.
+
+
+Stephh's notes (based on the game M68000 code and some tests) :
+
+ - The current set is a Japan set (0x0a5c.w = 0x0000), so there must exist
+ a non-Japan set which is AFAIK not dumped at the moment.
+ I have however no clue about what should be the value in the non-Japan set.
+ - Use AQUARIUS_HACK to be able to change the game to English language
+ via the FAKE Dip Switch.
+ Change the Dip Switch then reset the game to make the changes effective.
+ - I haven't found a way to enter sort of "test mode", even if there seems
+ to be code (or at least data) for it.
