![]() There is also a row of numbers by 'Offset (h)' at the top, that is where you are in that row of numbers. They are just there to tell you where you are in the rom. The numbers on the left are called offsets. All we need to worry about are the numbers in the middle, and on the left. Just type in a number then switch to hex to see what it is in hex.įirst open your rom in HxD, and you should see something like this:ĭon't worry about all the weird symbols on the right, we won't need them. If this is confusing just use windows calculator. 11 is B and, 16 is 10 in hex because it's the 16th number in the list. ![]() ![]() So 10 in the normal number system (decimal) is A in hex. It is the number system for all computing, and consists of letters AND numbers. I'll leave that as exercise for you.Hex is short for hexadecimal. However, it would be nice with some symmetry between the skills, hardware and software levels. With a stealth skill of 255 you don't have to upgrade your gear or software to complete missions with ease. I changed the offset to FF ,saved the file and opened it up in decker. The third change has the right values in the before and after files. The second change is unknown to us, and although it has changed in value by 1, it does not match the before and after values we expect. The first change is in an offset we know is money. This time there was more than one change. I then saved the file and opened spent-money.dsg and sneaky-guy.dsg in HxD to do a file compare. However I spent it right away on stealth. This is a great time to save a baseline file (which I didn't) and then you can load it and reuse it to find the offset for each skill. I disabled the alarms and disconnected from the matrix. Next it's time to do a mission, I picked a simple IO mission and found the controlling node right away. Now you have the option of spending this money, if you do then remember to save a new base line file for comparing against before you do the next step. Open decker again and load your modified save game to confirm that you have $65535 (FF FF = 65535). Now we change this value to FF FF to give ourselves a decent amount of cash. If the changes matches both values then you should have the right offset. Here is where some basic hex knowledge comes in handy, we know we started with $100 (xx in hex) and you should know how much money you had left in your second save game. Now comes the fun part, open both dsg files in HxD and use the Analyse->Compare->File compare operation (ctrl+k). This time I named mine "spent-money.dsg". Next enter the shop and spend some of your $100 starting money. This is your baseline file to compare against. Then as soon as we enter the game, save it. So lets fire up decker, choose to start a new game then pick your character's name and image. ![]() Grab a copy from, microwave some popcorn and lets have from fun. It is a "hacking" game based on neuromancer/shadowrun. Basic understanding of hex (or this cheat sheet)įor my tutorial I am using the free game Decker.A game where you can save your progress.The internet (to read this article and download software).In order to follow this "tutorial" you will need five things: Modifying your save games to gain endless wealth or lives is very simple as still a valid technique today, and I'm going to show you how to do it. In my circle writing walk throughs and cheat sheets for games and posting them to "our" BBS was the quickest way to fame. Before the internet most people would get their cheat codes from gaming magazines, gaming guide books or a BBS. ![]()
