[COMPILING] what kind of (additional) build options are provided?

about these instructions: http://www.lakka.tv/doc/Compiling-Lakka/
What other options could I use for building, in addition to those indicated?
For example: AUDIO+=pulse AUDIO-=alsa, FS-=FAT32 or CORE=, etc…
Also, I’m quite new to GitHub: when building, I’ll get the latest cores’ versions at that time, right?
Thanks, bye! :wave:t3:
