0.06b: Fixed it loading roms other than the default
0.06a: Fixed a problem with screenshots
0.06: (Core)
      Experimented with an alternate memory access method, which didn't help performance much
      Halved timeslice sizes
      Move CLUT to be a memory region rather than part of the chip
      Compute buffer size and pixel aspect ratio accurately in the OP, pass to window system
      Cleaned up CPU and RISC interrupt systems, added CPU stop object interrupt
      Rewrote Tom PIT to the correct spec (and fixed the stall bug I found in it too)
      Rewrote Jerry PIT to correct an awful inaccuracy. However, to get AvP sound right
            I had to add a hack to multiply the rate by 4. I don't understand why, I don't
            know where the bug is, and in particular I don't know if I should apply the same
            hack to the Tom PIT as well.
      Fixed a bug that was causing writes to the start of some memory regions to be misdirected
      Rewrote OP towards optional line-granularity
      Added option to disable DSP altogether
      Added all DSP wavetables, or at least guesses at same
      Hacked around a problem that was causing the 'superzapper recharge' sample not to appear in T2K. Also
           hacked the 'gappy sample' issue by slowing the music replay rate down 2% in the native
           sound routine
      GPU/Risc fixes: truly embarassing bug with sat8, equally rubbish bug with move pc,
            MMULT instruction, kick off small timeslice on all RISC starts to avoid race if the RISC
            sets a status flag which the 68k then checks, possibly the largest bug in the history
            of errors in RISC interrupts (which weren't saving flags), ADDQMOD instruction,
            PACKUNPACK instruction, PC register, hidata register
      OP bugfixes: don't infinite loop on zero vscale, abort if hit address zero, fully
            clipped objects off left side fix, some colour transparency, RGB16 conversion
            was incorrect, scaled objects needed signed height, 8-bit OP scaled objects,
            improved horizontal scaling accuracy, added RGB24 mode
      Blitter bugfixes: bit to pixel expansion bits were reversed bit order, 32bpp phrasemode
            blits were using wrong address mask, moved srcshade inside transparency check, fixed
            8-bit phrasemode blit alignment several times, added byte-to-phrase blits
      Blitter improvements: added blitter A1 inc sign, added blitter Y inc, added 8-bit
            srcshade, additive blits
      (Debugger)
      Track RISC history (some of these need compile switches)
      Append register name comments to disasm output
      Added help menu in debugger because I'm too stupid to remember my own commands
      Tidied up some registers
      Kill OP object option
      (Windows)
      Fixed fullscreen on certain widescreen machines
      Connected OP screen width hook
      Went up to W4 and fixed most of the additional warnings
      Reversed left and right sound channels
      Fixed the remaining bugs with fastcall and switched to it, for a small performance gain
      Added joystick button configuration
      (All)
      Clean up headers, clearly define core/window system interface
0.05: (Core)
      Blitter speed optimisations
      RISC core speed optimisations
      OP speed optimisations (contributed by Gravy)
      Screen capture support
      Defender 2000 compatibility fixes (some contributed by Firefox, still broken)
      Native sound for T2K to avoid high DSP load
      (Windows)
      Rewrote keyboard system
      Rewrote D3D fullscreen switch - should have fixed fullscreen change crash
      Fixed D3D cards that support StretchRect but need no filter specified
      Options dialog box for configuring controls and directories
      Saves options into registry
      Avoid window shrink with repeated restart or fullscreen switch
      Made fullscreen mode select a wide ratio mode if desktop is in a widescreen mode
0.04: Fixed no joystick support
      Added sound capture and level meter
      More internal work for porting
0.03: Cleaned up fullscreen code a little
      Cleared all fullscreen backbuffers at init
      Added automatic resizing of window if too big for screen
      Fixed (in theory) mono and 8-bit WAV files
      Added joystick/joypad support
      Internal code cleaning in preparation for Mac/Linux ports
0.02: Fixed bug with some video cards
0.01: First release
