/******************************************************************************************* 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 ... */ #include "emu.h" #include "cpu/z80/z80.h" #include "sound/ay8910.h" class poo_state : public driver_device { public: poo_state(const machine_config
