Notice: No Graphics Were Harmed in the Porting of These Games. That's right, these games are straight ports from their original 16-32 bit glory. Granted a lot of these games are fairly recent, at least compared to the other company's collections dating back to the 8 bit era, but games like Ultima: The Black Gate, Mutant League Football and Desert Strike still have a very retro feel to them, even if they aren't as old as Pitfall.
Sound, like the graphics, also hasn't been touched, as far as I can tell. Sure some of the music from Wing Commander or Road Rash sounds clearer than what I remember, but I'm not sure if that is a result of the porters cleaning up the audio, or the better quality speakers on the system... well, better quality than what I had at the time anyway.
