Super CTF Land

Description

This challenge is from the internal BYU End-of-Semester CTF (Fall 2022).

Welcome to Super CTF Land, the first custom BYU CTF retro game! It looks like someone may have hacked the ROM and left behind a secret. Give it a play and see if you can find that secret!

This challenge provides you with a file named Super_CTF_Land.gb. A quick web search or prior knowledge of video game emulation reveals that this is the file extension for a GameBoy game. To run it, download any GameBoy emulator software- I used SameBoy. Then, using your emulator software, load the Super_CTF_Land.gb file and run it.

Once you are presented with the game’s title screen, hit the ENTER key or whatever key your emulator’s A or START button is mapped to, and you’ll be put in the game’s first level. At the top of the screen, you’ll see the flag.
