Do you want to try out a new mod file for SRB2 and just want to run it like a exe file? This thread might be helpful.

First you will want to start off with this line of code:
Code:
@Echo off
this line of code makes the line of code doesn't show up.

Next were going to be using the executable which in this case:
Code:
@echo off
srb2win.exe
this will run the batch file.

After we want to add a file so.
Code:
@echo off
srb2win.exe -file srb2006.wad 2006music.wad
this will add the files when the executable opens.

I want it to be opengl so.
Code:
@echo off
srb2win.exe -file srb2006.wad 2006music.wad -opengl
this will run the game in opengl mode.
check out here for more command lines. http://wiki.srb2.org/wiki/Command_line_parameters

After you want to save it as Filename.bat.

Now you are finished. Happy Batch making!
