The emulation is flawless and the application is very straight forward as after installation all your Genesis games will be available from the same interface not separate like your PC Games. Programming the keys into my Logitech gamepad emulating a keyboard is so easy. The topic was discussed earlier here as TPU and the prices are maybe a litttle bit much, especially the current Sega Classics pack that goes for about $35. http://store.steampowered.com/sub/4391/ Certainly a bit much for a pack that includes some B level games and some games that have also been emulated for other platforms like Golden Axe on Dreamcast. (The Dreamcast emulation was flawed and audio quality suffered greatly as the console could not do the midi music justice at all and it sounded a lot worse) Yes I do still have a working Dreamcast. So far I've been testing it out with Golden Axe, the first Genesis game I ever played many years ago circa 1990, and I suck royally. After I wasted all my lives I got a D rating for my efforts. The music would really be so great if it was fully orchestrated but asking for a remix of a $2.99 20 year old game is a bit much. It sounds pretty much like the Genesis I remember and the picture quality with the enhanced filter is amazing for such an old 2D game. I sure hope they release all the classic RPGs like Phantasy Star 2, 3 and 4 among many other great Genesis games like Streets of Rage. I hope this all works out and Nintendo steps to the plate, too. You would think that Sony could cash in with Playstation games as well but they like to offer them in the handheld format so that might be a detractor but there is a huge market of Steam customers to tap for all the major console producing companies. I would think that Steam could really turn emulation into a hugely profitable business for the companies involved and an exciting one for us gamers.
