Did you know you can get a real dirt cheap handheld console like the R36S (for $40) that can run most PS1 games, as well as many PS2 and N64 games, and anything below that... Even a few GameCube games.
For twice the price you can get more advanced chinese made android based portable handheld emulator consoles that can run all PS2 games and most PS3 games... For even more money you can get similar devices that are SteamOS compatible.... Meaning you can get a low end SteamDeck for half the price of the real thing.
So one of those options can probably get you your preferred Final Fantasy game in a pocket sized portable console.
You may think this knowledge is a blessing, but it's a curse. Spoiled for choice and it ultimately comes down to money and whether you actually want more screen time.
