Sonic The Hedgehog 3

Another easy one to get, simply collect 50 rings - it can be done on the first stage.

If you are struggling then just take your time and try to avoid the badniks and traps. There is a save feature that you can use to save your progress at any point in the game so if there's a section that you think you're going to lose your rings by getting hit, save it and then attempt and if you fail, re-load the game save.

This achievement is as simple as it gets! All you'll need to do is collect 50 coins without getting damaged by any enemies. Just take your time and it'll pop the 10G in no time!
