Examples on the mrk.sed.pl don't work

[LessNick]

The links given in the README.md with an example of launching programs from the site mrk.sed.pl do not work:

GET https://atari.ha.sed.pl/https://atarionline.pl/utils/9.%20ROM-y/Systemy%20operacyjne/Atari%20OS%20v2%2083.10.05.rom net::ERR_FAILED 404 (Not Found)

The path to the ROM file is incorrect. The emulator tries to download a file from the address:
https://atarionline.pl/utils/9.%20ROM-y/Systemy%20operacyjne/Atari%20OS%20v2%2083.10.05.rom

But there is no such file on the site, and the correct address is different:
https://atarionline.pl/utils/9.%20ROM-y/Systemy%20operacyjne/XL%20OS%20v2%2083.05.10.rom

Also, program files cannot be downloaded from third-party resources due to blocking by CORS policy:

If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
