2. Folder Setup & Extraction

  1. Create Root Folder: Create a folder named RO_PreRenewal (e.g., C:\RO_PreRenewal\).
  2. Extract Core Files: Extract 1_Database, 2_Server, and 3_Client into your RO_PreRenewal folder.
  3. Move Assets: Extract and copy the three GRF files into the 3_Client folder. Extract your chosen BGM folder into the 3_Client folder.

3. Launching the Game

  1. Start Database: Run laragon.exe from the 1_Database folder.
  2. Start Server: Run runserver.bat from the 2_Server folder. Keep the four command windows open.
  3. Start Game: Run Ragnarok.exe from the 3_Client folder.
    (Use Ragnarok_XKore.exe if you are using OpenKore).

Security & Optimization

  1. Antivirus: To prevent slow loading or false flags, exclude the RO_PreRenewal folder from your Antivirus/Windows Security.
  2. Verification: If you wish to "diff" the client yourself using WARP, the unpatched EXE 2020-05-20bRagexe.exe and profile 2020-05-20bRagexe.yml are available in the TOOLS folder.

How to Create a New User

1. Open your browser and go to http://localhost (make sure to run laragon.exe first).

2. Go to Register (You can use a fake email and even the same email for multiple accounts).

Troubleshooting

Problems Solutions
Ragnarok.exe won't run Download all the GRF files one by one, DO NOT download all at once.
If you download the GRF files as a ZIP, it means you did it wrong. RE-READ AGAIN
Run opensetup.exe for the first time, and change resolution in graphic setting section and use DirectX 7 graphics API
Install Visual C++ Redistributable Runtimes All-in-One (This also applied if you can't run the server because missing MSVCR110)
Client runs poorly (low fps or stutter) Change power plans to High Performance in Windows Control Panel to make CPU clock speed stable.
Open opensetup.exe » Turn on Restrict mouse to window
Right click Ragnarok.exe » Properties » Compability » Turn on Disable fullscreen optimizations

Extra Notes

  1. - To keep the server organized, I've documented all modified folders and files here.
  2. - DO NOT TOUCH THESE FILES/FOLDERS UNLESS YOU KNOW WHAT YOU ARE DOING.
  3. - This section is for 2_Server folder.
  4. - These files/folders have been edited to suit this server needs.
  5. - You can use Visual Studio Code to compare between the original rAthena files with these files listed below to know the difference.
  6. - AVOID editing core files directly. Use the import folders in conf and db to override settings.
  7.   This keeps your modifications organized and prevents merge conflicts during updates.
  8. - If you edit the source, you need to recompile the server to make the changes you've made take effect. Watch How to Compile rAthena 2026 in Windows 10/11.

Use yaml2sql.bat then run sql file to re-generate sql files in sql-files folder if you want to update FluxCP database.
Since yaml2sql.bat doesn't convert mob_skill_db.txt to SQL, you can use .convertmobskilltxt2sql.bat. Don't forget to install Perl for Windows beforehand.
