Those were released by heterejeneo and at the time was fine but, it had bugs with the tools so then the release for K5/6 was given and that superseded the old files and was way more stable than the old release.
I cant remember which part of ragezone that you have mentioned that the ver 4 is for gmtool convertion... as of now I am having trouble with the TantraParam.tpa from xml2txl ver 4, it crashes my gmtool... I am still searching the forum on how to do the right way of converting the param.xml to param.tpa, no luck... any tut or hint how to do it? thanks much
Do yourselves a favor though. Don't use Kiwi Firewall. That program does not actually help with DDOS attacks other than possibly blocking legit traffic to the game. Just get a server that has DDOS protection and do some research.
