my stepdad is blind and really interested in cars. i recently bought a Logitech steering wheel and he showed a lot of interest in it. since it would be near impossible for him to drive I looked in to racing games that could be played by someone who is visually impaired. i found a couple games that did this through controller rumble or audio, but the one that stood out was rad. in the research paper they claimed most who tried it preferred it over other blind racing games. however, i cant seem to find any sort of download for it. i told him about RAD and he seemed very keen on trying it.

if you know where or how to get it, i would be grateful.
