Would someone help to replace the Z80 core with cz80 ?
I tried but it crashes before displaying the big invader.
Here is what i did :
| | | Cz80_Init(&Cz80
_struc);
Cz80_Set_Fetch(&Cz80_struc, 0x0000, 0x1fff, (u32)&ram[0x0000]);
Cz80_Set_ReadB(&Cz80_struc,(CZ80_READ *)&cpu_readmem8);
Cz80_Set_WriteB(&am
p;Cz80_struc,cpu_wri
temem8);
Cz80_Set_ReadW(&Cz80_struc,(CZ80_READ *)&cpu_readmem16);
Cz80_Set_WriteW(&am
p;Cz80_struc,cpu_wri
temem16);
Cz80_Set_INPort(&Cz80_struc,(CZ80_READ *)&cpu_readport16);
Cz80_Set_OUTPort(&Cz80_struc,(CZ80_WRITE *)&cpu_writeport16);
Cz80_Set_IRQ_Callba
ck(&Cz80_struc,s
ms_irq_callback);
Cz80_Reset(&Cz8
0_struc);
...
Cz80_Exec(&Cz80
_struc,228*262);
Cz80_Set_IRQ(&Cz80_struc, 1);
Cz80_Clear_IRQ(&
;Cz80_struc);
...
unsigned int cpu_readport16(unsigned int port)
{
return 0xFF;
}
void cpu_writeport16(unsigned int port, unsigned int data)
{
}
static u8 cpu_readmem8(unsigned int address)
{
return ram[address&0xffff];
}
static unsigned short cpu_readmem16(unsigned int address)
{
return cpu_readmem8(address) | (cpu_readmem8(address + 1) << 8);
}
static void cpu_writemem8(unsigned int address, unsigned int data)
{
ram[address&0xf
fff]=data;
}
static void cpu_writemem16(unsigned int address, unsigned int data)
{
cpu_writemem8(address, data & 0xFF);
cpu_writemem8(address + 1, data >> 8);
} |
instead of
| | | z80_reset(0);
...
z80_execute(228*262
);
z80_set_irq_line(0, ASSERT_LINE);
z80_set_irq_line(0, CLEAR_LINE);
...
