So Box64 and Box86 are normally emulators that allow you to run x86 and x64 software on Arm devices such as a Raspberry pi.
You can run desktop apps such as steam and mostly importantly to me, WINE (Windows software)
Normally you've had to compile both Box86/Box64 separately in the past, however...
Alright, so I'm gonna pretend you're completely new to Linux as I was and try to compile a simple program.
A lot of programs need to be compiled from the source (for some reason). I think it's because if they want the program to work on different architectures (such as ARM, PowerPC devices etc)...
