OpenBOR (Open Beats of Rage) is an open source engine to play Beats of Rage.

Beats of Rage is a freeware open source video game and moddable game engine made by Senile Team ( ) and inspired by Sega’s classic Streets of Rage series. The term “moddable” means that the program allows users to create their own content, and thus their own beat-’em-up game, which is then called a “mod”.

Beats of Rage was first made available for download November 2003. It was not advertised in any way other than by word of mouth, yet it soon gained enormous popularity.


Widescreen (480×272) mods supported.
Widescreen (16:9) displays supported without stretching.
No aspect ratio distortion with any mod regardless of display. Horizontal/vertical black bars are used when needed.
Can now be run from a USB flash drive or FAT32-formatted USB hard drive.
OpenBOR no longer depends on SDL Wii. All I/O handling is done natively through libogc.
Performance boost due to using GX directly for video instead of going through SDL.
