---------------
* added support for Master System compatibility mode (Z80 ports access mode), incl. Mode 5 rendering.
* added Mode 4 rendering for both Genesis & Master System modes.
* added alternate BG planes rendering functions (should be faster on PPC architectures).

* fixed EEPROM types for Brian Lara Cricket & NBA Jam TE (verified on real cartridges)

[Core/General]
---------------
* added Master System compatibility mode emulation (automatically enabled when loading ROM file with .sms extension).
* improved savestate stability & compatibility (support for old 1.4.x savestates is preserved)
* various code cleanup & comments.

[Gamecube/Wii]
---------------
* fixed cheat codes handling when several codes affect same ROM address.
* improved input controller detection on menu exit.
* improved key remapping dialog box to match emulated device
* changed Menu key for Gamecube controller to allow MODE button mapping

f34b8d4557 * added support for Top Shooter (custom arcade board using modified Genesis hardware)
* added emulation of a few additional unlicensed game copy protections (fixes 777 Casino crashing randomly)
(NB: it appears that most of those unlicensed games were already patched by ROM dumpers, emulating copy protection hardware only for documentation)
