Part of what made ocarina such a great tool for cheating was the power behind it. It did indeed cause alot of mayhem online, but it also allowed a myriad of great and innovative hacks in other areas. Many games weren't negatively impacted by ocarina, but sadly there will always be negatives. I fear without ocarina a great deal of games won't be possible to easily mod. Ocarina was a way to write easily write codes to directly read and write RAM. That in itself opens up huge possibilities for game modification good or bad. The greatness in ocarina for me didn't come from cheating, i never used it for that. It's the experimentation and innovation that made it worthwhile.
