RetroArch singlehandedly takes big strides to cater to an underrepresented group of people, opening up a whole new world of entertainment.
See here the perspective of a blind person talking about the new accessibility features available in the latest nightly versions of RetroArch. This and more will be available out of the box starting as of version 1.8.2.

For decades, video games have offered entertainment for many people. Childhoods were changed by iconic franchises like Super Mario, Zelda, Final Fantasy, and Castlevania. People can reasonably count on others to understand the meaning behind video game references.
For people who are blind, however, these games could only be enjoyed through their great music, or by reading novelizations or fanfiction. Audio games have been created, to fill the void of video games which could not be played, an some blind people braved fighting games by memorizing menus and special attacks, but audio games were few in number, and didn’t usually have much content.
Emulation has helped many people who are blind relive their childhood playing fighting games. With the rise of machine learning, however, blind gamers now have another tool in their arsenal: optical character recognition, the extracting of text from images. With this being a part of many screen readers, blind people could use that to read menus, character select screens, and unspoken dialog.
RetroArch is the first “emulator” to now offer Accessibility to blind people by speaking the interface. Along with the text-to-speech AI service, RetroArch has not only become the first emulator to implement accessibility for blind people in menus, but also in reading game text as well.
This doesn’t, however, mean that all games are accessible. A blind person still cannot get Super mario into the castle in Super Mario 64, nor defeat Lavos in Chrono Trigger, although perhaps one could probably play Radical Dreamers now. Much more work will be needed to make video games completely accessible to blind people, even portraying health bars in fighting games through sound cues. Even so, the accessibility of RetroArch means that blind users of Windows, MacOS, and Linux can enjoy the state of the art in video game accessibility through emulation.
How to enable accessibility
Once you’ve downloaded and installed RetroArch, there are two ways to enabled accessibility. The first way is by turning it on via the menu. Once RetroArch is started press: right, then up seven times, then enter (on some systems this could be the x key), and then right. You should hear “Accessibility Accessibility Enable ON” at this point. If this doesn’t, restart RetroArch and try again. This method navigates the menu, which may change in later versions, so you should read the RetroArch Accessibility Docs for any updated key presses.
The second method is to enable it via the command line. This is done by running the RetroArch executable (for example: retroarch.exe) in the command line or terminal. On windows for instance, once you’ve opened the command line, navigate to the RetroArch folder, and run “retroarch.exe –accessibility” and you should hear “RetroArch Accessibility On. Main Menu Load Core.” From there you can navigate right to the settings submenu, and then down to the Accessibility option, and then turn set Accessibility Enable on. Now you’ll be able to start RetroArch with accessibility from outside the command line as usual.
If these options don’t work for you, it could be that your OS does not have the required speech libraries or voices that RetroArch needs. For windows, RetroArch uses the Windows Narrator, which you can read how to download additional voices for here. On MacOS, it uses the “say” command, which you can read how to download voices for here. And on Linux it uses Espeak. For Ubuntu, you can install espeak by running “sudo apt-get install espeak” and then “sudo apt-get install espeak-data” for the additional voices.
Using the AI Service with Accessibility
The AI Service can also use the Accessibility narrator for Text-to-Speech. This can be done by going to the AI Service settings section, and changing the AI Service Output to “Narrator Mode.” This handles the Text-To-Speech, but the AI Service still needs to process the game screen to get that text. You can follow the setup instructions for the AI Service here.
While people without disabilities have been able to play thousands of video games, both current and past, blind people have not had the ability to enjoy more than a handful of video games. Through
emulation, this is beginning to change. Games which were once only playable if one could memorize menus and selection screens are becoming accessible using OCR, and more will be possible through the hard work of developers who may build upon this foundation for accessible video game emulation.
RetroArch is the first emulation center to provide accessibility for the user interface, and an AI service to perform OCR on video games, allowing blind users of all three major desktop operating systems to enjoy playing fighting games now with knowledge of any text that appears onscreen. It is hoped that this is only the beginning of a great advancement in accessibility, with RetroArch paving the way to even greater video game accessibility for people who are blind.
RetroArch is available as a Mac and iOS/tvOS application. You have to sideload it on an iOS/tvOS device though, and the Mac version is not available on the Apple App Store due to store policies preventing its distribution in adulterated form.
