Allow controller reconfiguration for improved comfort.

Application: All titles

Test: Does your title allow the player set the button mapping of each action possible in game?

Provide alternative controller support.

Application: All titles
Description: Do not limit the player to only using standard controllers or keyboards, or require a standard controller for use of your title. Seek to offer support for at least one alternative controller and/or simplified control scheme. Consider those unable to use traditional input methods such as joy-pads and microphones.
Accomplishment: This allows the player to use non-standard controllers or special build controllers that work better with them and for their needs.
Test: Does the title allow use of a various controller types, or does the title only recognize one controller?

Offer sound alternatives.

Application: All titles in which audio is being used to give information about gameplay

If yes, is this the only way this information is conveyed? If no, this feature is being used correctly. If yes, reference a color chart that displays colors as a colorblind person may see them. Do the colors appear to be the same on the color chart? If no, the title is using this feature correctly.
