/*******************************************************************************************
Uncle Poo (c) 1983 Diatec
actually an hack of Joinem? Or there's something even more similar?
driver by David Haywood and Angelo Salese
TODO:
-merge with jack.c driver, this is a modification of that HW (with colscroll)
-accurate game speed (controlled by an irq)
-a bunch of unmapped read / writes
-writes to ROM regions
*******************************************************************************************/
/* Stephh's Notes:
'unclepoo'
SYSTEM bit 7 is sort of "freeze", but it doesn't seem to have any effect when playing
(only during boot up sequence - unsure about attract mode)
DSW1 bit 5 is "Bonus Lives" :
- when Off (0x00), you get an extra life EVERY 30000 points
- When On (0x20), you get an extra life at 30000 points ONLY
DSW1 bits 6 and 7 might be used for difficulty (to be confirmed)
DSW2 bit 0 is the "Cabinet" Dip Switch :
- when Off (0x00), cabinet is cocktail
- When On (0x01), cabinet is upright
This affects write to 0xb700 (bit 7) and reads from 0xb506 and 0xb507 ...
BTW, remove PORT_PLAYER(1) and change PORT_PLAYER(2) to PORT_COCKTAIL ...
DSW2 bit 7 overwrites the number of lives :
- When Off (0x00), lives are based on DSW1 bit 4
- When On (0x80), lives are set to 255 (0xff) but they are NOT infinite
Other bits from DSW2 (but bit 5) don't seem to be read / tested at all ...
