NoFear 1,406 Posted July 24, 2017 XOR SEARCH: This method of search is very unique and not intended for you to try as a first method. Once you've tried all memory types, all ranges, unknown increased and unknown decreased and all fail, this method might be what you want to do last. XOR is a simple encryption method, but without the key, you can't know the value. And games lately (not all) will have a key that changes on value change, making finding these types of values EXTREMELY difficult if not impossible... Until now. HUGE thanks to @Enyby The search All the games I've come across that use this method have all been dword, so I'll stick to dword. Also most games (except For Emblem Heroes and some parts in GunPie) the XOR key and XOR value are 4bytes apart. Let's say you have 25 gold. To search 25 with xor key 4 bytes away 25X4 If you know your value is within a range but not 100% on value, so you know you collected about 40 to 45 gold, your search can be 38~50X4 Then when you collect 10 more 48~60X4 During these searches, if you want to eliminate many results that are most likely not it, you can do a does not equal 0 and does not equal the value. You search 500X4 Followed by ≠0 ≠500 Then you can resume the XOR method. This search cannot be done with a group search. If done properly, can do unknown changed/unchanged. Editing You have a couple ways you can edit values. Edit results and if you want to edit to 12345 Put 12345X4 If you want to edit multiple values keeping xor and doing a different value for each. If you have 3 results from searching 500X4 Edit results 100;5000;15000X4 First value week be edited to 100 2nd 5000 and 3rd to 15000. The other option ,goto address, copy value above (xor key) using the xor calculator built into GG, calculate value and got can type values and re-encrypt with proper xor key. Increment edit If you have 5 results and want each to be different, separate each edit with a ;. So for 5 results 5;10;15;20;25X4 Value 1 will be 5, 2 will be 10..... Then you can figure out the correct value, revert and remove the wrong values and continue with editing that one value. List of known games using XOR protected values. Tiny Miners Bullet Force Gunpie Super Mario Run Fire Emblem Heroes (SP: 8 is xor offset. Level: 24 is xor offset) Touch Tank Target Acquired Futurama: Worlds of Tomorrow Pokémon: Magikarp Jump Skychamp HAWK: Freedom Squadron Candy Crush Heroes Infinite Stickman Legend (XOR offset 8) Zombie Pandemic Survivor 18 Share this post Link to post Share on other sites

NightHawwwk 2 Posted July 24, 2017 (edited) Any chance of a video tutorial explaining this please? Im having trouble understanding this. Thank you! Didnt see [video to come soon] part. My bad... Will be waiting! Edited July 24, 2017 by NightHawwwk 0 Share this post Link to post Share on other sites

Logic11211 2 Posted July 25, 2017 In pokemon magikarp jump I'm able to do increment edit...works flawlessly... I'm having problems with coins... The value still reverts even after editing... Is there a max amount of coins???? 0 Share this post Link to post Share on other sites

EichZen 7 Posted July 25, 2017 @NoFearThank you for the basics of the guide! I've been trying to hack Realm Defense TD but I keep failing. I'm guessing the XOR key are really far apart? Is it possible to use odd numbers as xor keys? so far the examples I've seen are X4 X8 X16 X24 and so on 0 Share this post Link to post Share on other sites

Been doing this type of hacking for a while (few years?) and the more I help others hack 'everything' the better I get and the more I learn as developers try to protect their games. 0 Share this post Link to post Share on other sites
