  because i don't recommend you to always use it since this can cause sound bugs with some games.
* Added the possibility to force software blit for Fullscreen "Normal" and "Double" render mode.
  This option can be enabled/disabled only by key-shorcut (see in the shorcuts section) because almost
  people don't need to use it, try it only for speed issue.

(06/04/2000) Changes Gens 0.4 <- Gens 0.39 :
--------------------------------------------
A lot of changes for this new release :

- Gens configuration saved in file ! (finally)
  (You can specify your own file name for special configuration)
- SRAM fixed and entirely implemented (saved in file).
- Mouse cursor now hidden in Full-Screen then you must use
  the right mouse button to access at popup menu  !
- Perfect recovering of sound after 'load state' (only with MZ80 core).
  Saves files are now bigger, but there are compatible with old format.
- DAC (few) noises fixed.
- Some little bugs with VDP DMA fixed.
- Others bugs fixed .....

About 80% (little more) of roms work correctly !
No error messages anymore (like "Starscream core error ...").
If an error occurs, emulation attempt to continue even if can crash.

(01/04/2000) Changes Gens 0.39 <- Gens 0.36 :
---------------------------------------------

- Joystick support added ! (directx 5.0 needed)
- Interlaced VDP mode added ! (can play at sonic in split mode but only with my 68000 core)
- Fixed (again) auto-detection for some others country ...
- Fixed H-Blank status in VDP
- Some others few bugs fixed (Alt-Tab key, ...)

SRAM not yet saved in file
Config not yet saved in file

(27/03/2000) Changes Gens 0.36 <- Gens 0.34 :
---------------------------------------------

- Gens now uses the new MZ80 core of Neil Bradley (v3.4)
  and it corrects some sound bugs !
- Fixed special version auto-detection (Toy Story ...)
- SRAM implemented (Landstaker, Light Crusader ... now work correctly !)
  but not yet saved in a file.
- Choice of the game speed added : NTSC (60 FPS) or PAL (50 FPS).
  If a game runs too fast, just switch to PAL version.
- Sound timing for some games (vector man ...) fixed.
- Fixed switch state shortcut.
- Fixed the stupid bug which exits after setting keys !
- Fixed load state crashes with starscream.
- ...

Joystick support not yet available :(

(21/03/2000) Changes Gens 0.34 <- Gens 0.3 :
--------------------------------------------

- Starscream 68000 is available, changes :
  - More roms work fine (about 75% :)
  - Faster than mine !
  - Debugger doesn't work with Starscream !
- RAZE Z80 core added, but there are some problems with certain roms aladdin, sonic ...)
  but it works better than MZ80 in other cases (animaniacs, contra4 ...).
- Shortcuts added (Save / Load state, frame skip ... see below)
- Sound is now stopped when clicking on menu or resizing the window ...
- Current directory stored (but not yet in a file, just when you keep gens running)
- Some optimizations -> some more FPS :)
- Bug fixes (DirectSound init, key settings ...)
- Others I can't remember ....

(14/03/2000) Changes Gens 0.3 <- Gens 0.24 :
--------------------------------------------

- Starscream 68000 core (faster and more accurate than mine) is now
  implemented but deactivated, it'll be active in the next version !
- DAC works now perfectly (can hear 'SEGA' chord in sonic games :)
- Many many fixes in sound and CPU timings:
  - All chips (68000, Z80, YM2612, PSG ...) are synchronized depending on the
    game type (PAL 50Hz / SECAM 60Hz) and PAL games work at 50 FPS in
    auto-frameskip mode.
  - Fix YM2612 timers.
  - Fix PSG rate.
- Can choose sound sample rate (you must reload the rom for that to take effect !)
- Some little others...

There are some glitches with the DAC speed with some games (just hear the voices in
aladdin, cool-spot, lemmings ...)

(08/03/2000) Changes Gens 0.24 <- Gens 0.2 :
--------------------------------------------

- I returned to MZ80 (Neil Bradley neil@synthcom.com) z80 emulator, it now works correctly !
- Preliminary sound emulation :
  - YM2612 works correctly :)
  - PSG works strangely :o
  - DAC doesn't work and only does some noises :(
  - Sound sync is not yet perfect !
  - Sound is played slowly with certain roms
- Fixed a bug in the window plane (Zombie doesn't crash any more ...)
- Others ...

(24/02/2000) Changes Gens 0.2 <- Gens 0.141 :

- I've entirely rewritten the VDP rendering :
  - More optimized and so faster ;)
  - Fixed Scroll A / Window conflict.
  - Added masks sprite features.
  - Added sprite limit feature (can see it on sonic 1 main screen)
    You can enable or disable it by 'Sprite Over' option in the 'graphics' menu.
  - Added 15 bits mode.
    No more bad colors on some video cards :)
- Fixed the VSRam read and write (vertical scrollings are now okay)
- I'm using RAZE (Richard Mitton richard.mitton@bigfoot.com) z80 emulator instead of MZ80
 (Neil Bradley neil@synthcom.com) due to unworking games with MZ80 (I may not use it correctly).
- Some changes in DMA transfers. (sprites of mario (no commercial) rom are okay).
- Full-Screen now works correctly.
  Full-Screen is faster than Windowed mode, just use it !
- Some others ...

Sorry, once again, the sound is not implemented, may be in the next release !

(08/02/2000) Changes Gens 0.141 <- Gens 0.12 Beta :

(03/02/2000) Changes Gens 0.12 Beta (Win9X) <- Gens 0.15b (DOS):
----------------------------------------------------------------

First important change: Gens works now under win9X and using DirectX !
Then some bugs appeared and some roms that worked on Gens 0.15b don't work anymore :(

- Screen size * 1; * 2; * 3; * 4.
- No V-Sync possibility for now.
- Debugger is missing because a lot of work is needed to make it work !
- Save/Load state added !
  I'm using Genecyst format, there are some bugs due to lack of info.
- The transparencies effects due to palette changes during H-Blanking work !

No sound yet !
