https://xp-dev.com/svn/aCis_community/ its a free SVN, you will need eclipse to download it, try searching for guides, im too lazy to explain everything :D
sorry, my bad :D never used to play with stuff like this. Always used to just DL mysql, navicat, install a random l2j pack and start playing, and now i had to install like 10+ programs to run this "Eclipse" lol.... 21st century..
EDIT:
I am getting errors on all the bat's. :
does it mean that I didnt compile them or something? Dunno how to actually use eclipse
EDIT 2:
followed this guide: http://acis.i-live.eu/index.php?topic=78.0
didnt compile when JAVA_HOME was set to jdk bin directory, changed to jdk's and it compiled successfully :) will check if it works now
EDIT 3: DUUUUUUUDE,
why do you have register-gs in 2 locations? + in build (where its working). solved.
