Problems / limitations
----------------------
* 32x and SVP are not emulated.
* 32x is not emulated.
#ifdef PSP
* SVP is not emulated.
#endif
* Various VDP quirks (window bug, scroll size 2, etc.) are not emulated,
as very few games use this (if any at all).
* Some games don't work or have glitches because of inaccurate timing and sync
between the emulated chips.
* The emulator is not 100% accurate, so some things may not work as expected.
Credits

* Charles MacDonald (http://cgfm2.emuviews.com/) for old but still very useful
info about genesis hardware.
* Steve Snake for all that he has done for Genesis emulation scene.
* Tasco Deluxe for his reverse engineering work on SVP and some mappers.
* Bart Trzynadlowski for his SSFII and 68000 docs.
* Haze for his research (http://haze.mameworld.info).
* Mark and Jean-loup for zlib library.

Changelog
---------
1.40
+ Added support for SVP (Sega Virtua Processor) to emulate Virtua Racing,
wrote ARM recompiler and some HLE code for VR.
* Changed config file format, files are now human-readable. Game specific
configs are now held in single file (but old game config files are still
read).
* Fixed a bug where some key combos didn't work.
1.35b
* PSP: mp3 code should no longer fail on 1.5 firmware.
+ PSP: added gamma adjustment option.
