It runs under the SDL2 audio and video libraries.Ī batch file is included as a method to quick-launch SRB2 with particular settings without use of a launcher. With the use of batch files ( such as the one below) or a launcher, command line parameters for this file can be set before starting the game. This is the executable for running SRB2 itself – clicking on this file will start the game. In most cases, modifying or deleting these files will cause the game to crash on startup. These are the files that are extracted from the self-extracting archive file for installing SRB2, most of which are required to run SRB2 itself.
