Sometimes the difference between a shareware version of a game and a paid version is as simple as flipping a bit. Finding that bit can be the tricky part.
As many know, I am a big fan of the game Pixel Dungeon.
Many of you also know about Lucky Patcher , a tool to mod Android games. Unfortunately, many of Lucky Patcher custom mods are obsolete and no longer work on newer versions of a game.
Now, why you might ask would a game developer who uses source code and Android Studio to make a game be looking at Lucky Patcher for a mod?
Pixel Dungeon has a special mode for those who purchase it. I have hunted through code to locate it to no avail
Lucky Patcher has a custom mod for a 1x version of Pixel Dungeon that doesn't work on the 2x or current 3x versions.
I extracted the patch data:
It reminded me of many PC tools that patch executables or UNIX GSAR/GREP, a simple HEX Search and Replace.
Examining this one can see only a single value is changed, 01 into 11 or 0 into 1.
0 unpaid, 1 paid
I obtained a copy of 1.4.3, ran the patch and it failed.
Perplexed, and after some trial and error, I obtained another copy (both from legitimate sources) with a different size. This time it worked.
I decompiled the 3 APK's, first, second, and second patched.
The two unpatched were not alike. One was nice and clean, from the developer site, the other larger and full of bloatware from Google.
It turns out that the free versions with public source code has none of the bloatware, however, it also has none of the registration and paid features.
Ergo, only the release from Playstore has the Patron payment code.
All of my releases are based on the free and clean source code, hence why I couldn't find the code to mod.
Now that I knew what to look for and where, I ran a side-by-side byte comparison of the unpatched and patched decompiled APK's.
Using a wonderful PC tool, this took seconds. I have provided a custom Sbenny release.

I had to turn off date comparison and turn on byte comparison.
For those acquainted with JAVA, SMALI, RegEx or BOOLEAN this sets the value of a constant to 0 or 1 and the rest of the code decides what to do with it based on the value.
Also, the constant is located in the Payment services code.
Sure enough, my Super Green Shattered Pixel Dungeon source code doesn't have this code.
I downloaded a copy of 3.2.4 from Google and checked, sure enough, there's the file, but the code had changed enough for the pattern search to break, rendering Lucky Patcher useless.
Decompiled APK's produce SMALI code, but that's not the same as assembly code or JAVA.
So, using MT Manager I opened up the 3.2.4 Google version and my own SG compiled version.
I manually applied the patch to the Payment code, and then I manually transferred my own SG patches to the Google version and created a hybrid mod.
The result, a Super Green Shattered Pixel Dungeon with Patron mode unlocked.

Oh, and the bloatware and analytics are removed... this is the Google version (modded) so one must automatically assume the game will have malware.
