When it asks you if you want to replace the existing file with this one, say yes.Then, Exit 7-Zip.ĭownload the "aapt.exe" file from here (This is a 100% original copy of the "aapt.exe" included with the Android SDK, if you don't trust this, download the Android SDK and get it from that)Īfter downloading, move it to the same folder your "UndertaleWrapper.apk" is in, now, for the important step, create a folder called "assets" in the same folder as the "aapt.exe" (NOT INSIDE THE "UNDERTALEWRAPPER.APK") copy all "*.ogg" files and the "credits.txt" from your Undertale PC/MacOSX installation to that folder. Go to the same "/assets" folder we saw earlier, and right-click "Paste". Now, right-click the blank file we downloaded earlier(UndertaleWrapper.apk) then hover over the bar that reads "7-Zip", then click "Open Archive".
Make a copy of the "data.win" file somewhere else on your computer, then change the name of that file to "game.droid" the right-click on it then "Cut". In the Undertale folder you will see a file called "data.win", if you don't see it, then scroll down. If you installed Undertale from Steam then while you are in Steam right-click the name "Undertale" in installed games then, Properties, "Browse Local Files". Next, open your "Undertale" folder from C:\Program Files\Undertale\.
Go to the "/assets" folder, you will see a file called "game.droid", this is the file which contains everything from the game(or should contain) (code, graphics, sfx, etc).
