MacFCEU 0.6a4
Bug fixes: DebugGenSetByte (and yet so little; 6 chars):
When affecting cheat RAM, wrote to the wrong real address!
(In other words, don´t use sb or cheat with 0.6a3.)
The setprg2 macro did setchr2r. Fortunately, it was never used.
VRCVII mirror for mapper 16 did HV instead of VH.
Added DebugGetAddrType for ´wh´ to tell you what address does what.
SnapName is on by default.
Leaner include´ing means faster processing/compilation time.
Revising [Calculate]Palette to be more accurate...

Another major bug! FlipByteOrder flipped data two times the size.
Fixed, but for backward-compatibility reasons, the bad version is
partly supported (it´d be better to just trash the old state files).

Mac OS: [ExitToShell patch] to ensure that `exit` is called.
(A call to ShowMenuBar, and VSync routine removal need to be done
regardless of whether the program crashes.)
Contiguous sound playback using the callback method -- finally!
Debugger: A stupid command line bug fix.

MacFCEU 0.6a2-0.6a3 (removed - too many serious bugs):
Some platform-unspecific code now put into the core code (i.e., debug.c).
Capitalization correction of more file names.
Put SDL networking src file back in since trying to write netplay for Classic
isn´t worth it.

iNES: Added handling of version 2, VS System case (untested), PPU detection.
Cleaned up the VSUni code, now uses correct bit values.
More accurate error messages in FCEU.c.
Zapper[, Family Keyboard] data added to ExState.

Sound: Rect filter values are now cast as int32 so negative amps. can work...

Input: default GamePad #2 buttons changed for all four GPs to be implemented.
Default #3 and #4 added (for testing purposes, obviously).
Family Keyboard/Scroll Lock(F14) xxxable added (was it removed?).
Fixed an input issue that caused zpong3 to constantly reset (Select+Start).

PPU: fixed UPALRAM read (2007h) bug. NEStress now only gives a "partial read error."

Game Genie: Ptr disposal on failure (crash fix).
Added GENIE.NES as 2nd to gg.rom.
Error messages no longer scream with exclamation points.
GENIE.NES now GENIE.ROM as to avoid accidental opening as a cart.
(Change the extension from .NES to .ROM, and you´re good to go.)
Fixed a rather stupid bug I introduced a while back.

Debug: cheat-RAM is also set for DebugGenSetByte.

Mac OS: Diamond mark only shown for when selection is denied.
A sound revision yields a 2A0x.a optimization.
I think I cleared up a case where the sound would be forced off,
and throttle wouldn´t take over. Other corrections...
Increased the application suggested/prefered sizes to 4000/3200KB
since iNES 2.0 and some boards may call for more memory.
Debugger: Added user step trace-flags (tf). Fixed bugs made via rewrite.
Trace-flags now uint16 (expansion). Added TFxx constants.
If echo is >1 (or bit #15 of tf), any kind of stepping will be printed.
Increased the maximum executed line store to 50.
Message Log: logtofile is now treated as multiplier of 512KB in clipping value,
or unlimited (0xFF).
Video: finally added refresh VSync (Classic only). I can´t say it works, though...

MacFCEU 0.5.6/0.6d1 (early release 2010.03.23):
Major parameter bug fix for new implementations that use SetxxxHandlerI.
Put the unused frame-skipping code back in ppu.c, commented out.

Sound: added FCEUISetRectFilterAmplitude. (Fun fact: it can be negative.)

Mac OS: diamond mark char used for partial mark check; PAL can´t be changed when
the video setting is fixed.
