Figured this deserved its own thread.http://code.google.com/p/genplus-gx/
This is old news, but Genesis Plus GX on the Wii now has Sega CD support.
What this means is that now you can play Snatcher on the Wii, with the Classic Controller as the Gamepad and the Lightgun via the Wiimote!
I played Snatcher via this method and it works incredibly well.
Also, Genesis Plus GX is the most accurate Genesis/Sega CD emulator out there. Add that with the ability to output via 240p component and wiimote light gun emulation and you got the most authentic emulation experience out there.
