+      mGBA is a new Game Boy Advance emulator written in C.
+
+      The project started in April 2013 with the goal of being fast
+      enough to run on lower end hardware than other emulators
+      support, without sacrificing accuracy or portability. Even in
+      the initial version, games generally play without problems. It
+      is loosely based on the previous GBA.js emulator, although very
+      little of GBA.js can still be seen in mGBA.
+
+      Other goals include accurate enough emulation to provide a
+      development environment for homebrew software, a good workflow
+      for tool-assist runners, and a modern feature set for emulators
+      that older emulators may not support.
