This is a WIP mod for the Android version of Dragon Quest 4. This is available as an xdelta patch and requires a copy purchased and downloaded from the Play Store. Anything else will not work
A couple short videos of the mod in action can be seen above. The first one is pre-v0.0.1, while the second is v0.1.2. For those interested, instructions are below.
Features:
Installation Instructions:
(Note: this mod can also be entirely installed without a PC if you do not have one, however my instructions assume you have a PC available)
1. First, you must purchase "Dragon Quest 4" on the Google Play Store
2. Second, you'll need to be able to download the files for the game from Google Play. There are various ways to do this (see above) but I recommend Raccoon as it has a good reputation and that's what i've used successfully.
a. Install Raccoon and once installed, enter the account info for the Google account you purchased Dragon Quest 4 under. It will ask if you want to use a dummy device for this -- this should be fine, just click "ok".
b. Next, search "Dragon Quest 4" in the top right of the window, select it and it should give you the option to download it.
c. Once downloaded, you'll get the option to "Show Files". It will open up a Windows Explorer window where the files are (should be somewhere under "Documents\Raccoon" by default)
3. Now you'll want a patcher that supports the "xdelta" format. There are tons of these, but i'll just throw Delta Patcher out there.
a. Download the patch files from this mod page.
b. In Delta Patcher, select the apk you got from Google Play under "original file:", and select the "apk" xdelta patch under "XDelta Patch:". Click "Apply Patch". When finished, it should say "Patch applied successfully" or the like.
c. Now do the same for the obb.
4. Now plug in your phone and copy the files over. I recommend placing the patched apk under "~\Downloads" for easy access and the obb will need to be placed under "~\Android\obb\com.square_enix.android_googleplay.dq4\" (<--- this folder will already exist if you've already installed Dragon Quest 4 on your phone)
a. Note: if you've already installed DQ4 on your phone, it will have to be uninstalled (sorry I really found no way around this, it won't install as an in-place update). This means your save files will need to be backed up or you will lose them. (Unfortunately, I believe they are also placed under /data, thus also requiring root to back up. Why this was done? I have no idea)
b. Access your downloads and tap the apk. Most likely Android will tell you that it won't allow you to install from unknown sources, so you'll have to grant permission to your file manager app. After that, it will also tell you that this version is not supported by Google Play Protect -- again, you'll have to allow it
c. After that, open up the game and enjoy.

(I tried to make this procedure as straightforward as possible ---> let's just say I realize through this whole endeavor why there isn't a real Android modding scene. At least...outside of certain circles... I would love for this to change)
