jump

Spoiler Alert!

If you are here to download and do the CTF problem (without viewing the source code), download the jump.bin binary here

Description

Jump is a SEGA Genesis ROM capture the flag "crackme" with a Kriss Kross theme. The objective is to reverse engineer the ROM enough to provide the correct controller input to recover the embedded "flag". The flag is simply alphanumeric phrase with each word seperated by underscores. Good luck!

P.S. I will upload the source code in the future after it's been solved and solutions become available online. (Or after I realize no one is going to download it at all).
