MegaMan 3 for the NES inspired me to buy (aka beg my parents) a Game Genie. Then, when it didn't have any codes out yet for MegaMan 3 I had to buy (aka beg my parents) the additional cheat code subscription that came in the mail every few months. Only took 4-6 weeks for the first one to arrive!
Man... life before the internet was slow.
Haha. I vaguely remember this Time Before the Internet. Sure seems strange.
