Is there an App or a Tool or something that makes 32bit Apps run in Catalina ?

I wish to play some 32bit Steam games on my Mac rather then in Windows.

... I was going to say Parallels or VMWare Fusion + a copy of macOS Mojave, but then you said games.

Dual boot to Mojave?

That's no different from bootcamp.

I don't like to reboot just to play a game.

VirtualBox?

Not sure if it works on Catalina but back when I used my 2012 MacBook Pro with High Sierra I was running Windows 95 on it for nostalgia's sake. Ended up EOLing the hard disk though (although SMART had been in FAIL mode for months prior--just happened to be using VB when it took a dump.)

VB runs as an app so no rebooting needed. Good luck getting external hardware to work though, such as a Gamepad, since I could never get VB to talk to any external device, only internal virtualized hardware such as video and wifi.
