How to use LRMSB

Ahoy-hoy good people of Donut Team, I wanted to type out this tutorial for people that seem to be confused how Lucas' RadMusic Script Builder works.
An official documentation is available here.

This tool can do the following two things:

• Convert (.rms) files to XML format
  
• Convert (.xml) files back to RMS

This tutorial will tell you how to do both, so let's begin!

Converting RMS to XML:
This is pretty simple. All you need is to put LRMSB.exe & your (.rms) file in the same directory then drag it into the executable. This should output an editable XML file with the same name.

Converting XML to RMS:
This part is a bit tricky. You need to make a batch script (.bat) file & run the command below:

start "" "%~dp0\LRMSB.exe" -inputxml "%~dp0\MyFile.xml" -outputrms "%~dp0\MyFile.rms" -rsdpath "%~dp0\"

Make sure to change "MyFile" to whatever the name of your file(s) is.

Upon running, you might run into some errors:

• Redundant {Attribute} attribute specificed on RSDFile found in "file.rsd" on line n of "PATH TO XML FILE".
  
  • This means some attribute is wrong with your RSDFile element in the xml file.
    
  • n represents a number.
    
• Could not find attribute {Attribute} for RSDFile "file.rsd" that isn't present in any specified RSD path on line n of "PATH TO XML FILE".
  
  • This means the attribute mentioned above is invalid or not present in your RSDFile OR your file does not exist.
    
  • n represents a number.
    
• Could not find RSDFile with name "{Name}" referenced on line n of "PATH TO XML FILE".
  
  • This means the rsd file mentioned above is invalid or not present in your directory.
    
  • n represents a number.
    
• Could not find {Element} with name "{Name}" referenced on line n of "PATH TO XML FILE".
  
  • This means the element mentioned above is not an element of your file.
    
  • n represents a number.
    
• Invalid floating point value "{Value}" for attribute {Attribute} on line n of "PATH TO XML FILE".
  
  • This means the attribute mentioned above has an invalid float (number) value or the value is not a number.
    
  • n represents a number.
    
• Invalid boolean value "{Value}" for attribute {Attribute} on line n of "PATH TO XML FILE".
  
  • This means the attribute mentioned above is neither true or false.
    
  • n represents a number..
    
• Invalid unsigned 32-bit integer value "{Value}" for attribute {Attribute} on line n of "PATH TO XML FILE".
  
  • This means the attribute mentioned above has an invalid integer value or the value is not an integer.
    
  • n represents a number.
    
  • A 32-bit integer ranges from -2147483648 to 2147483647 (inclusive). Anything outside is invalid.
    
• Invalid region resume type value "{Value}" for attribute {Attribute} on line n of "PATH TO XML FILE".
  
  • This means the attribute mentioned above has an invalid region resume type.
    
  • n represents a number.
    
  • The following list contains the only valid values for this attribute:
    
    • Resume
      
    • Restart
      
• The '{Element1}' start tag on line i position j does not match the end tag of '{Element2}'. Line n, position m. "PATH TO XML FILE".
  
  • You probably added a closing tag to an element that does not exist.
    
  • i, j, n and m represent numbers.
    
• Unexpected end of file has occured. The following elements are not closed: {Elements1, Element2, ..., Elementi}. Line n, position m. "PATH TO XML FILE".
  
  • You probably forgot to close one of the elements mentioned above. Go back & check your file and close them.
    
  • {Elements1, Element2, ..., Elementi} represents an inductive sequence, depending on how many elements you have.
    
  • n and m represent numbers.
    
• System does not support 'i' encoding. Line n, position m. "PATH TO XML FILE".
  
  • You probably changed the encoding. You shouldn't do that.
    
  • i is any invalid encoding, use "utf-8".
    
  • n and m represent numbers.
