Is hacking sprites in a Amazon Kindle game possible?

[Plint Michigan]

I bought Dragon Quest for my Kindle reccently, and upon watching a video fight of the final boss, I found out that the final Bosses dragon form is kinda small. I wanted to make it bigger for when I fight him to give him more pressence. Is there a way to do this?

That sounds like an awful lot of trouble to go through for one boss fight.

If it's anything like Square-Enix's other releases, the game will likely be packed in an "opaque binary blob".  It is probably possible to make changes, but that is not something that is regularly done and it would likely be a lot of work.

And of course once you hack the game, you would have to jailbreak your Kindle to let you install arbitrary packages.  And I'm sure Square has some sort of DRM in place to discourage such alterations.

IIRC Dragon Quest I-III are based on older cellphone releases, while IV-VI are DS.  If may be older than the obb setup, I'm unsure.

Wow, all that for one image? That sounds kind of stupid, especially for something I won't be making money off of.

That's your clue right there: if it was easy, someone would be trying to make money off of it (and failing, and making the news).

But what I'm trying to do is harmless, I just want to make a minor hack for myself. If anything, I may want to let others try it for free, but I wouldn't charge money for something so simple.

And that's fine – but my point is, you should not expect it to be so easy to make alterations to the game.  If it was easy to change the graphics for the final boss, it would be just as easy to change the rest of the graphics as well and easy for unscrupulous people to try to make a quick buck.  It is in Square's best interests if making such alterations is a difficult task.

(To be clear, I have absolutely no affiliation with Square and would point you in the right direction if I had any more ideas on how to proceed.  I'm just saying, there are good reasons to expect even making a minor hack for yourself to be enormously difficult in this case.)

Although Jorpho makes a good point consider the following.

Kindle OS is Android clone. Your game should be working ok on any Android.
Usually games are locked per user ... so if you been able to play your game on any Android device, you may try:
- Get Android emulator - I will suggest Nox or mEmu.
- Make sure your game work well on the emulator.
- Root the emulator's Android. From that point you should have all the freedom to delve in your game.

I play Final Fantasy Brave Exvius and I have seen people rip off character animations, so that gives me a clue, that wasn't done trough screenshots, rather direct access to files of the game.
