Below are the batch scripts I have been using to convert the binaries to text (and back). Put the .bat in a directory. Copy ConvertData_Rebellion.exe to the directory. Copy GameInfo\, Mesh\, Particle\ and Window\ to the directory. Double click the .bat. Files in all four sub-directories are converted. These .bat have been working well for me so far.
conv_to_txt.bat:
for /f %%f in ('dir /b .\GameInfo\*.entity') do ConvertData_Rebellion.exe entity .\GameInfo\%%f .\GameInfo\%%f
for /f %%f in ('dir /b .\Mesh\*.mesh') do ConvertData_Rebellion.exe mesh .\Mesh\%%f .\Mesh\%%f
for /f %%f in ('dir /b .\Particle\*.particle') do ConvertData_Rebellion.exe particle .\Particle\%%f .\Particle\%%f
for /f %%f in ('dir /b .\Window\*.brushes') do ConvertData_Rebellion.exe brushes .\Window\%%f .\Window\%%f
conv_to_bin.bat:
for /f %%f in ('dir /b .\GameInfo\*.entity') do ConvertData_Rebellion.exe entity .\GameInfo\%%f .\GameInfo\%%f txt
for /f %%f in ('dir /b .\Mesh\*.mesh') do ConvertData_Rebellion.exe mesh .\Mesh\%%f .\Mesh\%%f txt
for /f %%f in ('dir /b .\Particle\*.particle') do ConvertData_Rebellion.exe particle .\Particle\%%f .\Particle\%%f txt
for /f %%f in ('dir /b .\Window\*.brushes') do ConvertData_Rebellion.exe brushes .\Window\%%f .\Window\%%f txt
