cycleTime error in JR NZ Operations

[TXWSLYF]

The code has some minor issues. While attempting to dynamically determine the value of cycleTime based on the value of the zeroflag, the problem is that cycleTime is determined during CPU instruction initialization based on the initial value of zeroflag, which is always set to false. This leads to cycleTime always being equal to 3.

  this.addOperation({
    get instruction() {
      const value = memory.readSignedByte(registers.programCounter.value);
      if (value >= 0) {
        return `JR NZ 0x${value.toString(16)}`;
      } else {
        return `JR NZ -0x${(value * -1).toString(16)}`;
      }
    },
    byteDefinition: 0b00_100_000,
    cycleTime: !registers.flags.isResultZero ? 3 : 2,
    byteLength: 2,
    execute() {
      if (!registers.flags.isResultZero) {
        const jumpDistance = memory.readSignedByte(registers.programCounter.value);
        registers.programCounter.value++;
        registers.programCounter.value = registers.programCounter.value + jumpDistance;
      } else {
        registers.programCounter.value++;
      }
    }
  });
