Please support the petition - and if you're this way Sony (and Microsoft) isn't it time to start making some positive moves instead of backward steps?
We, PS3 owners and the members of Alt-Controls.com & AbleGamers.com, request that customizable controller settings should be added to the PS3 firmware.
Right now controller layout options are rather limited in most of the games available for PS3. Left-handed players, accustomed using the left analog stick to aim and also disabled gamers with specific needs in the controller setup would benefit from such a feature. Even "regular players" could take advantage by remapping the buttons to their taste. Not to forget about the players who are used to the legacy control layout.
Technically this should be feasible. For example, PSP received this feature in the 3.95 firmware for the PSone games: "While playing
PSone games on your PSP, you can now customize how the buttons are assigned by going to [Controller Settings] > [Assign Buttons] and select [Custom]."
