When my injury happened, I got extremely depressed. Because I had no finger movement, I figured there was nothing I could really do any more. Eventually I found help to mod a controller. Thanks to remapping options I’ve been gaming ever since.

You can remap buttons to your liking in Borderlands 2 on PS Vita. I mapped Sprint to O and Melee to triangle

Standard for PC games but rare on consoles, remappable controls are one of the best value accessibility features. Many people with motor impairments, whether permanent (eg. stroke), temporary (eg. broken arm) or situational (talking on a phone while playing) benefit greatly from being able to move essential controls into positions that they are able to reach more easily, for example with a single hand, or resting on a table-top using only the top buttons. It also benefits the huge numbers of people who simply prefer playing with their own set-up.
A recent petition by askacapper.com resulted in over 80,000 signatories requesting remapping as standard across the industry.
There is a common misconception that remappable controls result in TCR/TRC certification issues. This is not true. It does not, for example, affect requirements about X/O use, or about multiple triggers.
