My son is a Sonic completist and wanted to run Sonic R on his Windows 7 PC. While some note this is possible, it's a MAJOR hassle, and something that DOES NOT HAPPEN right out of the box.If you want to run this on a Windows OS made after 2003, you'll need to run this game in a specially emulated window using open-sourced, third-party software, PLUS you may need to tweak the source code itself, depending on your hardware.Sound like an undertaking? Well, it is.What makes this worse is that my son solved the game in just a couple days. That made it too short of a diversion for the amount of time and hassle I put into making it run on his machine.In short, unless you're a PC guru with time to spare rutting around in code and third-party software settings, skip this.
