There's a new Genesis emu with a debugger.

There's a new Genesis emu called Exodus that has a debugger, I thought you advanced code hackers would like to try it out. It's in its first release, so don't expect too many options, but it is trying to be a cycle-accurate emu like bsnes.

To run it, you also need to download the Visual C++ 2005 SP1 x64 Runtime.
