Many years ago, I worked on a product that provided a bunch of old emulated games. We properly licensed them, but many of the license holders no longer had the original ROMs, ripping the game data off of some of the really old consoles was quite difficult, and the only ROMs available publicly were cracked copies with demo's added. That was the birth of the demoscene, which was awesome, but bad for us trying to legitimately provide these games. So we ended up cheating. We used the cracked versions of these games, but we always loaded the games from a state just past when the demo would play, making them look normal and legit. Thank God all those early cracks put their demos only at the start and not, like, between levels 1 and 2, or we'd've been screwed.
