Write a short program in java which modifies the original games binary files to replace the values in the appropriate location. Refer to the picture on the second page for the modified values.
Assignment Description. This assignment is designed to introduce to you how malware can infect com piled programs, give you exposure to using a hex editor to understand computer code at a machine level and how security researchers inspect binary code to understand software at a low level. I love playing video games. Some of my earliest memories of childhood was sitting in front of a computer playing computer games. I'd love to revisit some of my old favorites, but as a professor, I have very little time to actually sit down and play games these days. So, I need your help. I want to play one of the all time great RPGs, Ultima V, but I have no time to go through the grind of leveling up and maxing out my stats. Running the Game. The game will probably not run directly on modern operating systems, but it will run just fine under DOSBox (a DOS environment designed to play older games). Grab DOSBox from here DOSBox will require a bit of setup, but the game should run under DOSBox without any additional tweaking of the game itself First, play the game enough to establish a character and get a feel for how the game is played. If you have experience playing CRPGs, then this game will be at least somewhat familiar to you. Then, you will save the game by pressing 'Q' and then alter the game's files to give your character maximum stats and gold. You can check the character's stats by pressing 'Z' and then selecting the highlighted character on the right It will be up to you to locate which file(s) are necessary to modify and what values to place into those file(s) at specific locations. Completing this assignment will require you to use a binary hex editor. I have listed a few here if you do not have one, but feel free to use whatever editor you choose: OS Program Windows Fr In MacOSHex Fi Linuxhexedit Bl irm The final stats on your main character (the one with your name) should look something like this: Attribute Value Str Int Dex HP Max HP xp Gold Assignment. Probably the most difficult part of this assignment is locating where in the game to make the modifications. I recommend spending a good amount of time figuring out how the internal structure of Assignment Description.
