Using the Mega Drives GameGenie on Sonic 2 (10 Ring Cheating Special)
An example of how the GameGenie works I basically went to this great website below:
https://gamefaqs.gamespot.com/genesis/916377-genesis/faqs/50188
Found a cheat I liked, typed in the 24 digit code / three 8's using the A button but depending on the game could be more or less and pressed the start button when I was finished.
Then during the game, I suddenly had 10 rings / invincible to a degree at least but the game genie is that simple just input the code using the a button and press start than during the gameplay you will find out if the code has worked or not.
Hopefully, after viewing this cheat cartridge in action, it will convince you it's worth buying :D
Also, here's a link that shows instead of a games list you enter codes manually.

Also here's a link of a playthrough of Captain America & the Avengers using the Game Genie and a visual example of adding a cheat code for this game:
