NES (EUR) Game Genie codes by Cyperium

Super Mario Bros. 2 (E):

These codes enable you to walk into subcon from anywhere when you press SELECT. I didn't notice any bad effects when I played through the game (using warpzones).

Also there are places where the game isn't designed to go into subcon, the game will hang in those places (namely inside pipes, and vertical scrolling areas).

Super Mario Bros. 2 (E):

View ending, ending will be shown when the level starts. The last two codes are the graphical setup but only applies for the first screen of the ending (the part where he pulls the plug off the pipe).

TAXYUTAA
IAXNOTYE

Works on real hardware but not on my cartridge version of Super Mario Bros. 2 for some reason (all the (E) versions I could find on emulators go to the ending, and I couldn't replicate the results I got from my version, where he enters the level but it doesn't scroll down so he dies). I tested with the Everdrive on real hardware with one of the (E) roms and it works.

Also works on US version.

Super Mario Bros. 2 (E):

Managed to shrink down the code for displaying the ending when you start the stage to four codes (the last two is for the graphical setup, but I'm searching for a solution that requires only one code for the setup since I want to be able to use the codes on a regular cartridge using 3 codes total). I still haven't been able to get the codes to work on my cartridge though, so I'm trying to find a solution to that as well. Works on emulator and on the Everdrive N8.

GSNTIGVX + OVNTTKKV + TAXYUTAA + IAXNOTYE - View ending when you start the stage.

Will update the codes in the database once I find a solution that works on a real cartridge.

Super Mario Bros. 2 (E):

SEIVPX - Hidden "THANK YOU" message revealed on the character select screen (the A in THANK YOU is replaced with some other graphics though). Graphics and animations are glitched when starting the level and throughout the game. To my knowledge there are no THANK YOU message at all in Super Mario Bros. 2, I will try to find a code revealing the message without any other glitches.

ESLVTO - Hidden "THANK YOU" message in character select (The A has the wrong graphics), graphics are glitched in character select and in pause screen.


In the prototype version the ending has a THANK YOU message (https://tcrf.net/Proto:Super_Mario_Bros._2_(NES)), that is probably what is seen here.
