You should clone this repository at the same directory level as mega65-core is. Compare with this:
commit e6efb397cb9d77810887c66ca27d0efd9178f897 (HEAD -> px100mhz, origin/px100mhz)

Say: make
Result is kick.bin, and also kick-src.diff for diff against the mentioned mega65-core
source files.
To test on the board: make board
You may need to modify settings though in Makefile.
version.a65 is 'hacked' only for having a strong signal, that it's not the "normal" kickstart for now!
LOT. It's totally a some hour try&error thing ... Without even trying to do things the right way. Also many warnings, ZP<->absolute addressing problems on import/export, etc etc. TOTALLY MESS!!!!
