comment How do I implement a retro-style password-based “savegame” system?
@NPSF3000 OP clearly says "Retro Style" and references Megaman to confirm, which is not ambiguous. Learn about the subject matter, understand that this is not related to security, and please stop trying to defend what started as an honest and forgivable ignorance.

comment OpenGL picking performance: ray casting vs. color picking
Ray casting maintains the same fixed cost with varying screen resolution and field of view settings. Ray casting can query your spatial partitioning scheme with a much simpler intersection geometry (A ray, instead of a trapezoid.) to find meshes which need to processed. I say "more appropriate" because it's able to take better advantage of the known information (Where the user has clicked.) to process less candidate intersections.

comment OpenGL picking performance: ray casting vs. color picking
The situation matter so much. The two methodologies have vastly different implications. One example: If the user is to drag across the screen during picking, clearly use a pick buffer. If the user is to only select once, then maybe ray casting is more appropriate.

comment Calculating pitch angle to hit a target using a projectile that has fixed speed
This is not gonna help your problem... but if the player is out of range, isn't the best choice to aim upwards at an angle which will produce the optimal distance, to increase the chances of the player walking into the arrow mid-flight?

comment DirectX is the camera a point or a plane?
The plane interpretation is called Orthographic, the point interpretation is called Perspective. It depends on your projection matrix.

comment How can I obtain information about the GPU in Cocos2d-x?
It sounds like you're calling without a context ;) Have you initialized an OpenGL ES context, are you running in the thread that initialized it?

comment Why are shadows not snapping to the objects?
I don't use Unity but this clearly looks like Peter-Panning caused by too large of a bias

comment How to create normal map from bump map in runtime?
Theoretically you can try any discrete differentiation operator. They are approximations, maybe you can achieve higher visual fidelity with other operators. I've chosen Sobel just because it's simple and fast.
