I think we should add download links, guide links, and wiki links, so here they are.

RCX breaks on the newest client so here is how to get it working:

1. Download RCX and extract it to your desktop or something. Use this version: http://forums.irowiki.org/showpost.php?p=1260715&postcount=1228
2. Copy your RO directory to your desktop too.
3. Replace your clragexe.exe with this version: https://dl.dropbox.com/u/105253377/clragexe.zip

Now whenever you want to run RO with RCX:
4. Run RCX.exe from the RCX directory
5. Run the start.bat in your copied RO directory (Do not click Ragnarok or RangarokClassic exe, as they will run the patcher and overwrite the shit you just did)

To play the game normally jsut use the links from the start menu, the vanilla and RCX versions you have shouldn't mess with eachother.

If that doesn't work just let me know and we can try to troubleshoot it. Also this is the guide I used, but I think that it overcomplicates the steps:
