+Genesis Plus GX is an open-source Sega 8/16 bit emulator focused on
+accuracy and portability.
+
+The source code, initially based on Genesis Plus 1.2a by Charles
+MacDonald has been heavily modified & enhanced, with respect to
+original goals and design, in order to improve emulation accuracy as
+well as adding support for new peripherals, cartridge or console
+hardware and many other exciting features.
+
+The result is that Genesis Plus GX is now more a continuation of the
+original project than a simple port, providing very accurate emulation
+and 100% compatibility with Genesis / Mega Drive, Sega/Mega CD, Master
+System, Game Gear & SG-1000 released software (including all unlicensed
+or pirate known dumps), also emulating backwards compatibility modes
+when available.
+
+Genesis Plus GX supports usage of actual BIOS image files rather than
+emulating them. Only Sega CD/Mega CD emulation requires a real BIOS to
+work. It is recommended to use a BIOS from a Model 1 system, but others
+are expected to work too.
