For me, it looks like these commands are ready for the [AUTOEXEC] section of the DOSBox configuration file.

Thank you very much.

What if I want to run other games in the future? Does that mean I need to change the autoexec lines every time I switch between games?

Another approach would be creating a customized copy of dosbox.cfg and put it in the game's folder. Afterwards you can create a shortcut invoking DOSBox with that config file.

E.g. dosbox.exe -conf d:\games\game1\game1.cfg {you can rename dosbox.cfg to something shorter or something you like}

It will tell DOSBox to use customized config file located at that folder. Thus, you can have all neccesary options under the AUTOEXEC section for each game.

Thank you, I got it to work on both issues!
But whenever I quit the game, the command prompt comes back on, with "Thank you for playing Rayman!" and C:> pops up. Is there a way for my DOS to automatically type "exit" AFTER I quit the game?

Put an exit command afterwards or inside a bat file if that's what's used for invoking a game.

Thank you again! 😁 It worked!
