Yet another of Sardu's ingeneous freeware emulators, genecyst can, after only a couple weeks in the making, run many genesis games flawlessly, which is quite an accomplishment.

Now that it has sound, there is no question that this is the best genesis emulator there is today!

This is the future of Genesis emulation and you shall see more great things in time...
