The fun thing is how these achievements are made.

Basically, people have to reverse engineer retro games and figure out where to find the condition that triggers the achievement.

Writing achievements is a good way to get started with ROM hacking. It's very similar to how you would do simple Game Genie codes too.

I love that the retro community is staying fresh and vibrant.
