This tool is designed to modify the RF.exe and RF_Online.bin file to allow a player who has 2 or more accounts to run 2 clients or more on the same computer at the same time.
It also has a language filter remover patch built in.

Version 2.5.1 - Released 2008-09-06

*DOWNLOAD* RFO MultiPatcher v2.5.1 -> RF Online -> -

Fixed the problem with the newest BR RFO release.

Version 2.5 - Released 2008-07-02

*DOWNLOAD* RFO MultiPatcher v2.5 -> RF Online -> -

Version 2.5:
In this version I've added support for BRFO thanks to user d1g0cs for providing the needed files to make it possible.
I've also added the ability to rename the patching dll so you can be more stealth like, and for BR I've also (I think anyway) disabled Hackshield
Now you should be able to use multi clients and be hackshield free.

When starting up the program if it has your RF Online folder stored in its data section the program will prompt you to choose either CM RFO or Brazil RFO
you will be prompted each time a scan is needed to be made however your choice is saved so in future you just need to hit OK, the files should be scanned quickly
then simply hit patch and you should be up and running with out a hitch, Renaming the DLL file is optional and its an option I added in case Hackshield gets updated or something.

Version 2.0 - Released 2008-06-23

*DOWNLOAD* RFO MultiPatcher v2.0 -> RF Online -> -

This is a complete rewrite of the multipatcher system which allows a player to use more then RF Online client at once, you can also remove the chat filter using this program.
Version 2.0 has been designed in such a way that it defeats the new checks put in place to stop changes that would allow you to run more then 1 client.
