Input Display 　

Pretty true to its name, this gives you an input display that you can drag around, and even customize a little.  Since it reads from the game's memory rather than directly from your controller inputs, it can also show you replay inputs.  It auto-detects any of the games it's compatible with when it's opened, so you don't need to connect it to anything or give it any information.  The author acknowledges that the reason it doesn't have anything for the photography games by default is because those games don't map all the input values properly.

Stuff You Can Customize
> KeyUpImg: The image used for un-pressed keys.
> KeyDownImg: The image used for keys being held down.
> BGColor: The general background color of the window, which uses hex values.
> Button positions are mapped to X/Y coordinates relative to the top-left of the window; the window will expand to fit things that have positive coordinates, so you can make your buttons as large as you want or customize where everything is however you like.  (To remove a button from being able to be seen, you can just give it negative coordinates; it's programmed not to display anything with negative coordinates.)
> The Address List lists per-line a game's executable name and the address of its input bit vector.  You can add or remove as many entries as you like, as long as you make sure it will work.  Valid addresses start with 0x, followed by 6-8 hex-digits.  This allows compatibility with future games.
