スクリプト。

function program_initalize(d, cpu_banksize, ppu_banksize)
{
	cpu_write(d, 0x8008, 0x00);
	cpu_command(d, 0x0000, 0x8000, cpu_banksize);
	cpu_command(d, 0x02aa, 0xc000, cpu_banksize);
	cpu_command(d, 0x0555, 0xc000, cpu_banksize);
	cpu_write(d, 0x8000, [0x0a, 0x15, 0]);
	ppu_command(d, 0x2aaa, 0, ppu_banksize);
	ppu_command(d, 0x5555, 0x0400, ppu_banksize);
	ppu_command(d, 0, 0x0800, ppu_banksize);
}

function cpu_transfer(d, start, end, cpu_banksize)
{
	for(local i = start; i < end - 1; i +=1){

	}
