Usage

A simple usage from example/main.dart:

import 'package:z80/z80.dart';

void main() {
  var system = System();
  system.memWrite(0, 1);
  // 0000| $A8 XOR b
  // 0001| $0E LD c, [address]
  // 0002| $07 [address]
  // 0003| $0A LD a, (bc)
  // 0004| $3C inc a
  // 0005| $02 LD (bc), a
  // 0006| $76 HALT
  // 0007| $AA
  system.load(0, [0xA8, 0x0E, 0x07, 0x0A, 0x3C, 0x02, 0x76, 0xAA]);
  print('before ram[7] = ${system.memRead(7).toRadixString(16)}');
  system.run(24);
  print('after  ram[7] = ${system.memRead(7).toRadixString(16)}');
}
