Level 3: Cheat Codes

You enter the third room of the dungeon, and find a paper with what you recognize as hex cheat codes. The door to the exit of the room has a gameshark and a keypad awaiting a cheat code entry. The list of codes reads:


Using the information hidden in the cheat codes, what is the cheat code that you enter to move on to the next level?

  • $\begingroup$ @Spacemonkey I almost named this one SCL, but decided to save it for a future level. You're very close (obviously) Dark Truth, there must be a subtle difference in the way we wrote the key. In my version, the last two 'parts' are written the same (hope that's helpful without being too spoily or revealing) $\endgroup$

I would say


Converting the hexcode to ascii gives:

A true gamer knows the code to decipher:BYAPPWZLSBADFCRQ

The code to decipher(Vigenere) the last part is the Konami Code (with two start buttons at the end. Only got this one after the tip in the comments. I only remember it with a single start button at the end while wikipedia doesn't say anything about a start button at all.):

BYAPPWZLSBADFCRQ : code[uuddlrlrbass] = hexmefourbillion

Converting to hexadecimal:

4,000,000,000 = EE6B2800 (base16)

I tried to do something with that last bit but putting it into an ascii converter again only leads to garbage.

  • $\begingroup$ That is the correct answer. The hint that it was the final step was that it, like other gameshark cheat codes provided, is a one byte hexcode. Great job getting to the bottom of it! $\endgroup$

Partial answer:

Converting the Hex codes to a string gives:
A true gamer knows the code to decipher: BYAPPWZLSBADFCRQ
(I assumed the non-hex line returns weren't part of it, anyway it can't be converted since they weren't in hex to start off with)

My guess would be that a famous cheat code is necessary to decipher that (like the konami code, but that gives nonsense. So probably another one like it)

  • $\begingroup$ Line returns were indeed irrelevant, just a a way to separate the hex into 1 byte cheats. As for the 'famous cheat code' you speak of, what did you try for the one you suggested? $\endgroup$

  • $\begingroup$ I tried the same as Dark Truth. I don't get the step where the konami code gives him hexmefourbillion. When I thought of the code I was thinking directions on the keyboard (i.e. up from B is H) $\endgroup$ Commented Oct 13, 2015 at 19:53
  • $\begingroup$ Spoilers Ahead: This was caused by my using the code that I used with my brother in Contra. This is apparently a variation of the 'normal' version which does not include Select or Start at the end. So the version I had was UUDDLRLRBASS, as opposed to UUDDLRLRBA or sometimes with a single S at the end I think in other games $\endgroup$
