BlastEm

BlastEm has the goal of being an extermely accurate Genesis emulator while still running on relatively modest hardware by using advanced techniques. Currently, there's a lot of work left to do on the accuracy front and there are a lot of optimizations I want to do, but BlastEm is still quite usable for certain purposes. Many commercial and homebrew games run well and the performance seems to be good on my relatively modest AMD E-350 powered laptop and Intel Atom based HTPC.

System requirements: 

amd64-compatible processor
