This allows you to cheat, some games can be much better providing you use only a few select cheat codes. It's not fun to cheat, but in some cases with older video games can be good, hence they called it an "enhancer"
For Sega Genesis system.
Rating E for Everyone.
Includes 5 things.
(2) Paper inserts.
(1) Game Genie cartridge.
(1) Code page of updated codes. (you can get new codes on-line now).
(1) Original Code manual.
I am the original owner-purchaser of this item, in fair condition, code page has stain, the manual is not perfect but not ruined, some minor scratches.
Has switch on the side to bypass the codes while it is running. you could replay instantly without turning things off and on.
I tested this with one game for more than an hour, cleaned the switch, and both ends of contacts.
Tested all OK, no refunds.
