Openbor has been updated for the Android OS:

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 modifiable game engine made by Senile Team and inspired by Sega’s classic Streets of Rage series. The term “modifiable” 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”.
Changes:
– fixed bug: num of plugged joystick > max num supported joystick_scan
– improved detection of joystick for android in SDLActivity.java mapping DPAD to keyboard buttons
– improved Android Hats/Axes detection add it into PollEvent() events
– added plug and play feature.
