New in 0.13:


Features:

+ Improved rendering quality for Tomb Raider 1 Gold:

  - geometry analysis (and correction) for removing background-colored
    gaps between landscape tiles
    
  - Runtime analysis of texture content for removing texture border
    artefacts caused by anisotropic filtering/mipmapping and the way
    TR stores its textures

+ adjustable Gamma Bias

+ Optimisations for the framebuffer emulation (Carmageddon, Falcon 4.0):

  - Altivec Velocity Engine optimised framebuffer emulation for maximum
    performance on slower machines
 
  - Fiddling with the cache lines upon rendering in order to optimise
    memory bandwidth usage on G4-based systems
    
  - Only downloading the parts of the framebuffer to the gpu that
    actually have changed, skipping any unchanged data

  On my 450Mhz Cube Carmageddon now plays almost fluid with a Radeon
  9000 at 1024x768. Falcon 4.0 users should also benefit from an
  improved framerate, but I haven't tested this thoroughly.


Behind the scenes:

+ Revised and extended preferences system
  - Default settings for all games
  - Game specific settings
  - Oh yes, older settings are again reset (hopefully for the last time)

+ Code refactoring as a preparation for Control Panel

+ Code refactoring as a preparation for texture replacment
  (a la Tomb Raider Xtra)


Bugfixes:

0.13a3:

- Installer includes uncompressed files for the rare cases where
  it doesn't work

- TR1 with gapfix enabled: pixel garbage into last row/column has been removed

- minor performance optimisations


0.13a2:

- The installer is working again
  (at least it did on one of the systems that users reported non-working)


0.13a1:

- Restoring the desktop gamma corection value should be more compatible

- Gaps in menu screen of Carmageddon 2 and TR3 resolved

- Gaps in TR2 main menu at resolutions higher than 640x480 alleviated
  (some have gone, but others are still visible if you look closely)
  

New in 0.12:

Features:

+ Gamma Correction (ColorSync must be installed)

+ Better performance (Especially in Carmageddon :^)


Bug fixes:

+ FutureCop radar and dispatcher window working,
  V1.02 not crashing anymore when pausing the game

+ Carmagddon retro mirror working

+ Carmageddon Map 3D-View working in all situations

+ Fixed crash when moving the cursor in Carmageddon Movie mode

+ Quake 3Dfx is working (actually it did all the time but
  it just wanted exactly 2M framebuffer/texture RAM)

+ Descent 1+2 display the cockpit and instruments

+ Switching between (emulated) Glide display and 
  Mac-Passthrough display preserves the color depth

+ Full support for undocumented Delta0 mode
  (no more special cases for Tomb Raider and Carmageddon)


New in 0.11:

Features:

+ New rendering engine (more accurate than in 0.10.1) allows better quality
  on suitable graphics cards (ATI 7500 and later or similar NVidia cards).
  Also fixes some rendering glitches such as the haze in Falcon 4.0 (which didn't
  show up in 0.10.1).
  To get the higher quality rendering, you need a graphics card with at least 3
  texture units, for example an ATI Radeon 7500. Smaller cards like NVidia GForce
  2mx or ATI Rage 128 will still use the simple rendering mode, and things will
  continue to look like in 0.10.1.

+ Full Scene AntiAliasing (FSAA) for ATI chips (only in the Classic environment)

+ Global texture smoothing and mipmapping

+ Tweaked a code a little to gain more speed on slower systems (does anyone notice?)

+ Original 3dfx-splash animation is displayed when starting a game in order to achive
  a more authentic appearence.

+ Better resource management

+ Added better support for pixel pipeline framebuffer writes.

+ Reorganised the code base

+ Lots of bugfixes and smaller improvements


Bugfixes:

Fixed in 0.11:

+ Menu backgrounds in Carmageddon 2

+ Psychedelic colors in Falcon 4.0 on Dual G5 machines with ATI 9600XT

+ Settings folder has been renamed to "MacGLide" in order to comply to the product name


Fixed in 0.11b1:

+ Several issues with the frame buffer emulation when pixel pipeline is active.

+ Unused texture units are disabled in order to speed up rendering.

+ Fa/18 Korea looks better because of fixes in the pixel pipeline frame buffer emulation (still not playable).

+ Fixed the color of the "3D" in the splash screen animation


Fixed in 0.11a2:
 
+ If the exact screen size isn't found, MacGLide tries to choose a slightly larger one.

+ Carmageddon 2: Menu backgrounds and loading screen images are now showing up. However,
  the colors are wrong so this needs some more investigation.

+ FutureCop LAPD Demo: Ammo count digits and some other parts of the headup display are
  not displayed correctly in the first level in single player. However, the ammo count
  digits are now visible in multi player mode. But I have just the demo, so I can't tell
  much about the full version (needs also some more investigation).

+ Tomb Raider 3: The in-game menu background now shows the current game scene in black & white.

+ Fa/18 Korea looks better because of texture format fixes

  
Fixed in 0.11a1:
 
+ Objects in Carmageddon (and probably other games) don't loose their transparency
  anymore when the fog becomes thicker.

+ Tomb Raider 1 Gold: Switching to the In-Game menu got a bit faster.

+ Less white screen appearence during screen resolution changes

+ Improved memory management hopefully fixes sudden exits in Falcon 4.0 that happended
  to some users when firing a rocket.

+ Haze in Falcon 4.0 rendered correctly.

+ Translucent Menu backgrounds in Tomb Raider 1 Gold.

+ Translucent Lightnings in Tomb Raider 1 Gold.

+ Fixed the multicolored skidmarks in Carmageddon (Splatpack).


New in 0.10:

Features:

+ Games can be played in any resolution whatever the monitor/LCD-display/hardware supports
  (See Readme.txt on how to enable this)

+ Configuration files are now stored in the System Preferences Folder in the subfolder
  "OpenGLide Settings".


Bugfixes:

Fixed in 0.10.1:

+ Fixed wrong screen resolution after flying a mission in Falcon 4.0


Fixed in 0.10:

+ Screenshots in Falcon 4.0 have not been rendered correctly


Fixed in 0.10b3:

+ Fixed making screenshots in Falcon 4 for Resolution settings other than 1

+ Fixed issues with logging searching for the display mode
  (resolution, colordepth haven't been reported correctly)

+ Config file from previous version is correctly replaced with default settings


Fixed in 0.10b2:

+ Fixed a startup problem on machines that do not report a screen refresh rate
  (that's usally Macs with built-in LCD-Display, like the iMac, or Macs connected to a
  Cinema display via DVI/ADC)

+ Fixed a startup problem on machines that don't support resolutions below 640x480
 
 
Fixed in 010b1:

+ Falcon 4.0 can be played in True Color

+ Tomb Raider can be played with movies enabled

+ Enhanced display quality in Falcon 4.0 by enabling anisotropic filtering
  (has caused purple pixel artefacts on buildings/bridges/plane artwork in 0.09)

+ Enhanced display quality in Carmagedon by sorting out some rendering artefacts
  when Anisotropic filtering was enabled (for instance on skidmarks)
  
+ Fixed crash in Falcon 4.0 when starting a second mission

+ Fixed crash in Falcon 4.0 on firing a rocket or if an explosion was occuring
  (some users had reported this problem while it worked for me and others)

+ Fixed problem with displaying the health status bar in Tomb Raider Gold 1

+ No more depth buffer problems on chipsets with 32bit depth buffer
  (for instance at the starting point of the first level of Tomb Raider Gold 1
  the portal was not rendered correctly in 0.09)


  
New in 0.09:

+ Fixed a bug that made white dots appear in the landscape in Falcon 4.0,
  and in other games that use 64x64 pixel textures 
  (Carmageddon also uses a lot of 64x64 bit textures)

+ Optimised memory allocation
  (may solve performance degration during longer sessions)
  
+ Using Altivec in some cases (if the compiler feels like)

+ Compiler settings have been optimised to minimise the memory footprint
  (with the intention to fit into the 1st/2nd level cache)  

+ Added ability to use complied vertex arrays to speed up the rendering

+ Mipmapping enabled by default

+ Anisotropic filtering default value  set to 16
  to achive the best rendering quality

+ Minor speed improvements by tweaking the code


New in 0.009rc3:

+ Fixed remaining Falcon 4.0 missing cockpit displays.

+ Fixed invisible Myth In-Game dialogs
  (did already work in the betas but was broken in 0.09rc2)

+ Fixed transparent areas in Myth In-Game-dialogs

+ Fixed distorted landscape tiles in Myth
  (actually that one has already been fixed in 0.09rc2)

+ Minor speed improvements


New in 0.009rc2:

+ Fixes for Falcon 4.0:

  * Canopy reflections and smoke effects appear correct.

  * Blue areas in virtual cockpit mode and the purple dots on areas/objects
    are gone (for instance the HUD or some weapons labels, probably others
    as well).
  
  * HUD texts are now readable. This bug actually affects all games since
    it solves a bug in the framebuffer rendering code that caused a dark pixel
    appearing right of any group of framebuffer pixels.

  * Instruments display correctly.

  * In-game menus are now appearing in front of the cockpit overlay.

  * The mission loading screen displays all stages of the flight preparation.
  
  *The screen doesn't turn upside down anymore for one frame when making
   a screenshot in Falcon 4.

+ Added a new fog emulation method that produces more accurate
  results than the previous one (for instance in carmageddon).

+ Added PedanticFrameBufferEmulation mode for enabling a more accurate emulation
  of the frame buffer (very slow but renders everything in the correct order).  

+ added fog emluation mode entry to ini-file

+ ini-file entry "InitFullScreen" has been renamed to "DisplayMode"

+ Added per-application default settings so games with known issues
  (for instance Falcon 4.0) can be run "out-of-the-box".
  

New in 0.009rc1:

+ Shadows and Lighnings in Tomb Raier Gold are displayed correctly

+ Fixed the "silly colors" problem in Carmageddon Splatpack

+ added minor speed improvements

+ Fixed the small icon mask of the shared library

+ Changed the file name of the archive to make it fit
  into the macos9 file name length limit

+ Corrected the list of tested games: Not Unreal Tournament, but the
  original Unreal has been tested


New in 0.09b5:

+ Anisotropic filtering improves image quality

+ Carmageddon is playable in Classic on a G4 450Mhz/GeForce 2mx thanks
  to a new framebuffer emulation (about 5 times faster than before)
  
+ Textures are rendered in RGBA when possible (should speed up things a bit)
  This also fixes non-working mipmaps on ATI Rage 128 chipsets

+ Colors of on-screen displays and progress bars in Myth are now correct

+ Falcon 4.0 added to list of supported games, complete with cockpit
  interior and on-screen display (see details in game section on how
  to get it working)
  
+ Tomb Raider 1 displays the background correctly in In-Game menus

+ Text in Tomb Raider is displayed correctly on MacOS 9 systems

+ Tomb Raider 1 + 2 can be played with movies disabled

+ Tomb Raider 1 & 2 can be played with movies enabled in windowed mode
  at 640x480 (just set InitFullScreen=0 in the ini-file). But in this
  mode, there are some zbuffer problems in the first level.


New in 0.09b4:

+ partial Support for ATI Rage 128 (mipmaps disabled,
  depth buffer size set to 16bit, some display errors)

+ Less memory usage

+ OpenGL GL_APPLE_packed_pixels is now a required gl extension

+ Simple fog emulation


New in 0.09b3:

+ Fixed annoying "3DfxGlideLib2.x not found" message

+ Cleaned up the log  output

+ Cleaned up the init file

+ Using the refresh rate requested by Glide and setting
  the monitor refresh rate to a fixed value works

+ Game overlays in Carmageddon aren't appearing anymore on
  top of the in-game menu for one frame when switching from
  the menu back to the game


New in 0.09b2:

+ Corrected a bug that caused In-Game dialogs in Myth to
  appear corrupted 

+ Trees and soldiers/Monsters in Myth are drawn without
  additional pixels around them

+ Missing menus/in-game graphics in Carmageddon
  (and probably some other games) are displayed
