I have coded some Python 3 emulator compilation builder scripts for most of the best GBA emulators. These mostly have the same features as the original Win32 executables, but the advantage is that they're multi-platform so if you're a macOS or Linux user you won't have to mess about making a Windows VM in order to try out the emulators.
