You can emulate this game on pc on emulators like DeSume or MelonDs. A quick Google search and a RU-vid guide on how to setup is all you'll need. I recommend DeSume.

Yes, but if I recall that mission with the police helicopter is hard and scanning the police helicopter and switching to it is more faster than trying and fighting it out in the first helicopter I scanned
Nice Speedrun. Also, you think you have it bad with sunlight? I'm forced to live with NO curtain at all. Except it only shines through during the winter and I'm free from dreaded sunlight during the summer
