* removed use of "long int" type for portability on 64-bit platforms.
* moved savestate zlib compression out of emulation core (for ports that don't use it).
* various optimizations.
[Gamecube/Wii]
---------------
* removed ROM load device selection from Load Menu: default ROM device must now be configured in menu settings.
* added specific load buttons, browsers & saved paths for each systems, this also fixes slowdowns caused by screenshot loading when browsing from slow devices.
* added support for left/right buttons as page up/down keys in ROM browsers
* added right analog stick as default "return to menu" key for Gamecube controllers
* added alternate remappable menu key combo for Gamecube controllers
* added an option to disable VSYNC (emulator is synced with audio hardware instead of video).
* added an option to boot system from "BIOS", with or without cartridge.
* added Master System & Game Gear "BIOS" support (files should be named bios_U.sms, bios_J.sms, bios_E.sms & bios.gg and copied to /genplus/bios directory).
* replaced "Hard Reset" button by a Soft Reset for systems having a Reset button (Mega Drive / Genesis & Master System)
* State & SRAM files are now only compressed when saving to Gamecube Memory Cards
* various fixes & cleanup.
* compiled with devkitPPC r26 & libogc 1.8.11.
