CPC++ is an accurate emulator for the Amstrad CPC family of personal computers. It lets you do pretty much anything you could do with an actual CPC.
It might seem odd to waste a powerful modern computer to run old programs that would fit on a 64K 8bits computer from the 80's, but once you'll get back in touch with those games, you might reconsider.
In addition to CPC++ itself, you will find here several tools to help you get (re)started on CPC computing.
