Adapting tilemap algorithm to support isometric tilemap
You don't need to change the parser, just the renderer.
The tiles will be at the 'same' place, except the projection is different.
The good news is that the good context 2d can do isometric just by ...

In a 2D game with an isometric camera (like Bastion) do I need to create a new animation for every angle the player is facing?
You can always just use 3d models instead of 2d art (3d models don't neccessarily mean a 3d game). Apart from that, not much. You could mirror half of the sprites, but that may interfere with the ...

How do I determine the draw order of isometric 2D objects occupying multiple tiles?
Here is a solution without resorting to 3D coordinates or splitting your sprite into 1x1 elements, that works if your objects occupy rectangular areas of tiles.

Rendering models in isometric view
Firstly, a 2:1 ratio is not isometric. It is a similar-looking dimetric projection (where two of the three axes are equally foreshortened, and the vertical axis is slightly less so)
Isometric ...

How can I generate isometric sprite sheets from 3D animations?
Blender is a good start.
To get "isometric" view you just need to configure the camera to orthographic projection and place it at the correct angle above and to the side of your model.
Then you ...

Is it a good idea to use per pixel collision detection in an isometric game?
The problem with per-pixel collision detection is that 1. it can be very slow and 2. your graphic design can have a lot more impact on your game mechanics than you would like. It is usually better to ...

How to convert 3D coordinates to 2D Isometric Coordinates?
You can represent the transformation between 3D world coordinates to 2D screen coordinates as a projection matrix:

Are the same number of tiles displayed in an isometric game regardless of phone orientation?
