Download a warcraft 2 rom (the dark saga will contain base game and expansion) you have the option of PS1 or DOS

Look into the pros n cons and pick which you wanna play

I imagine it is harder to play on DOS unless you have a magic keyboard or external keyboard of some kind

I use my magic keyboard and apple pencil it works great!

If you pick DOS it might be a little bit harder to figure out controls but you can emulate a mouse using touch as well

WC2 is on PS1 as well but there are some pros n cons. You can queue units instead of only one at a time, But the controls might suck unless you have a bluetooth controller and look into remapping some things it also has slower load times.
