GemRB (Game engine made with pre-Rendered Background) is a portable open-source implementation of Bioware's Infinity Engine.

It was written to support pseudo-3D role playing games based on the Dungeons & Dragons ruleset (Baldur's Gate and Icewind Dale series, Planescape: Torment). It should run on GNU/Linux, Microsoft Windows, OS X, possibly other UNIX derivatives and more. It is licensed under the GPL.


  • Almost full compatibility with bg1, bg2 and iwd1 (can be played from start to end)
  • Partial compatibility with pst and iwd2
  • Extensible plugin-based design
  • Many limitations of the original engine(s) were removed
  • High portability, including improvements for touch based input

  • Great open source game engine to use in small games.

  • I have installed BG1 BG2 IWD1 AND IWD2 on my laptop. then installed GEMRB onto my kindle fire hd. I then copied all the games over to the GEMRB file. I then run GEMRB but all it can find is the standard 3 things ie BG2 demo. What am I doing wrong?

  • Very good Software.
