How to make a PS1 disc ?

Hi everyone , i downloaded Thecontraadventure.iso file 77MB and i was wondering if i can make a real PS1 disc with only this file or do i need more files? If i need more files can you tell me which , only the name of the files not the download links. Many thanks in advance.

It's an ISO, so you can burn it with a burning app like Nero or Alcohol 120%.

Thanks a lot, with Alcohol 120% i make SUIKODEN II , and Mortal Kombat II real ps1 discs and my PS1 plays them just like a PS1 CD.

Yep, that's what it's supposed to do.
