The VG Resource

Is there a way I can get all the assets from these two games? I want to try and rip the models from the Android version of these two games (so I can see if the texture and model issue I have with the 3DS version exists on the Android version too), I tried extracting the games with a decompressor and just got pictures and random files, none of which looked like the plethora of model files you'd see in the 3DS version.

Please help, I want to be able to use the models from Dragon Quest VII and Dragon Quest VIII in MMD (MikuMikuDance) by December.
