This isn’t exactly what you asked, but I highly recommend emulation. I have had ePSXe downloaded on every phone I’ve had for the past ten years to play PS1 games. There are so many good titles, all of them free, playable offline. You might like Intelligent Qube Mr. Driller Devil Dice for puzzles. I love playing final fantasy, legend of dragoon, suikoden, Spyro, crash bandicoot. I don’t care about graphics, but I am a sucker for playing through a story.
