Ask HN: How can I recover and run my old mobile game from the 2010s?

I developed a game called "Putter King Adventure Golf" for iOS and Android back in the 2010s. It's long since disappeared from the app stores, but my son recently asked if he could play it, which got me thinking about whether it might be recoverable.

I'm wondering if there's any way to find a copy of it somewhere on the web (I assume it was probably pirated at some point during its lifetime). And if I could find it, what would be the best approach to get it running again?

Has anyone here successfully recovered and revived their old mobile apps? I'd appreciate any suggestions on:

* Where to look for archived APKs or IPAs * How to sideload/run old mobile apps on modern devices * Whether emulators might be a viable option
