Thunder Force II Game Genie Codes (USA, Europe)
This page contains the Game Genie codes that I have for Thunder Force II (USA, Europe), a game for Sega Genesis. If you're using an emulator you will be able to input the codes found on this page directly into the program and use them. For those of you who are old school and playing on a physical console, you'll have to purchase a Game Genie device to use them.
If you don't see the code you want on this page, I recommend you return to my Thunder Force II Guides Index and choose a different section.
