while the RUST_DOS.COM work in DOSBox, using FreeDOS/QEMU I always got this error:

Mmm. I can't remember if I had this problem too, but I made quite a few changes over here:

I'm not working in DOS these days and I'm not affiliated with this project, so if they work feel free to poach my work and open PRs here.

Hello @efa
rust_dos.com actually tries to read README.md, which should be placed in the working directory: https://github.com/o8vm/rust_dos/blob/master/src/dos_tests/file.rs#L6
