Re: NVDA support in DOS emulators like DosBox?

A horrible misunderstanding indeed.

A little research is obviously a dangerous thing.

Thank you for pointing out my mistake.

There is a horrible misunderstanding here. There are two programs

called Orca apparently:

- The first one (to which David linked below) is some sort of library

for performing chemical calculations and therefore is not really

interesting with regard to running screen readers under WSL.

- The second one is the screen reader called Orca (it's web page is here

and AFAIK it cannot be easily started under WSL as of yet.

The whole point of WSL is to make it possible for developers familiar with Linux tools to use a combination of Windows and Linux command-line tools and scripts for various tasks.

> Hi David. Thank you for the response. Unfortunately the command prompt in windows 10 doesn’t provide a complete DOS environment. The last version of windows to support true DOS mode was windows 95, if I’m not mistaken. Some retro gamers get really hardcore and actually put together old PCs with original hardware from the 80s or 90s and then install an older operating system like DOS. I don’t think I want to go quite that far LOL so I was hoping to run one of these emulators to give me the same experience. Unfortunately, I can’t seem to find any that are screen reader compatible. Some guys apparently have luck installing old versions of jaws for DOS within these emulators. I actually hunted down an old version of jaws for DOS and tried installing it within the emulator but I couldn’t get it to work, mostly because I have no idea what’s going on so I’m just typing blindly. I tried to use NVDA’s OCR feature to get a sense of what was happening but I gave up. Maybe I will give it another go later
