I'm honestly really sad that there's no simple way to get Flash games working anymore. Flash games were a huge part of my childhood and now all of them are basically unplayable without spinning up a VM.
If your wifi card has proprietary firmware, you can replace the card eventually. If the language compiles is proprietary, it's only a matter of time.
If flash had been open source, I'm sure there's be some small group of passionate devs keeping it alive. But as it is, this is simply not possible.
Let this be a warning if future choices.
