4Noah is a fantastic PC utility project allowing one switch gamers to control games that use two or more buttons (to a maximum of six at present). This is a wonderful endeavour that has so much potential to open up more games to more severely disabled gamers.
The above video shows a single button (the left mouse click) playing Tempest 2000. One click moves you left - click again to stop - click again to move right - click again to stop - and repeat... A rapid fire feature helps keep you in the game.
I would imagine some games will prove to be too fast for some gamers, which is where Speed Control utilities such as CPU Killer can assist a gamer further still.
The programmer of 4Noah is looking to develop the brilliant idea, and would really appreciate any support you can offer (ideas and technical). Contact the programmer here.
