Surprisingly, due to code at 0x2f77, credits are limited to 15 when coinage is set to 1C_1C or 1C_2C and to 14 1/2 is set to 2C_1C or 2C_3C. - Level is stored 1 byte (0xc70c), range 0x00-0x07 (code at 0x071d and 0x072c). This means that if you complete level 8, you'll restart from level 1 with its initial difficulty (based on the Dip Switch settings). ******************************************************************/ #include "emu.h" #include "deprecat.h" #include "cpu/z80/z80.h" #include "sound/ay8910.h" #include "includes/mrflea.h" /************************************* * * Memory handlers * *************************************/ static WRITE8_HANDLER( mrflea_main_w ) { mrflea_state *state = space->machine().driver_data(); state->m_status |= 0x01; // pending command to main CPU state->m_main = data; } static WRITE8_HANDLER( mrflea_io_w ) { mrflea_state *state = space->machine().driver_data(); state->m_status |= 0x08; // pending command to IO CPU state->m_io = data; device_set_input_line(state->m_subcpu, 0, HOLD_LINE ); } static READ8_HANDLER( mrflea_main_r ) { mrflea_state *state = space->machine().driver_data(); state->m_status &= ~0x01; // main CPU command read return state->m_main; } static READ8_HANDLER( mrflea_io_r ) { mrflea_state *state = space->machine().driver_data(); state->m_status &= ~0x08; // IO CPU command read return state->m_io; } static READ8_HANDLER( mrflea_main_status_r ) { mrflea_state *state = space->machine().driver_data(); /* 0x01: main CPU command pending 0x08: io cpu ready */ return state->m_status ^ 0x08; } static READ8_HANDLER( mrflea_io_status_r ) { mrflea_state *state = space->machine().driver_data(); /* 0x08: IO CPU command pending 0x01: main cpu ready */ return state->m_status ^ 0x01; } static INTERRUPT_GEN( mrflea_slave_interrupt ) { mrflea_state *state = device->machine().driver_data(); if (cpu_getiloops(device) == 0 || (state->m_status & 0x08)) device_set_input_line(device, 0, HOLD_LINE); } static READ8_HANDLER( mrflea_interrupt_type_r ) { /* there are two interrupt types: 1. triggered (in response to sound command) 2. heartbeat (for music timing) */ mrflea_state *state = space->machine().driver_data(); if (state->m_status & 0x08 ) return 0x00; /* process command */ return 0x01; /* music/sound update?
