0.8 -> 0.9
|
||||
There have been so many changes that this list can hardly be considered complete.
|
||||
The savestate system is totally changed and incompatible with old savestates.
|
||||
General/Core:
|
||||
- Convert to c++!
|
||||
- Added "high-level" check for DMAs and Timer for minor (really minor) speed up [shash]
|
||||
- Changed instruction execution to 16 at a time blocks (tested and stable) [shash]
|
||||
- Really minor memory access speed up (mainly added for clarity) [shash]
|
||||
- Fixes in IPC FIFO [CrazyMax]
|
||||
- Add Geometry FIFO simulation (New SMB and others games not freeze now) [CrazyMax]
|
||||
- Add cosine interpolation in the SPU (conditionally compiled) [zeromus,luigi__]
|
||||
- Experiment: always one silent SPU core at 44.1khz synched with emu for more precision.
|
||||
The audible core runs with the host, causing music to slow down but not tear or pitch bend. [zeromus]
|
||||
- Change savestate code to support loosely bound chunks and more easily other parts of the emu (GE, GPU).
|
||||
For this release, we have formatted the list into a high level overview of big changes and bad bugs relative to the previous release. Hopefully what you're interested in.
|
||||
This list does not include items which are solely performance boosts, for let us just say that virtually every system has been speeded up.
|
||||
|
||||
* The savestate system is totally changed and incompatible with old savestates.
|
||||
* The 3d system should be considered rewritten.
|
||||
|
||||
General/Core:
|
||||
enh: Convert to c++
|
||||
enh: Add functions for a lid open/close. Holding key (default "Backspace" in Windows port) while game is freeze/non freeze. [CrazyMax]
|
||||
enh: Add secure area decryption from ndstool [zeromus]
|
||||
enh: Change savestate code to support loosely bound chunks and more easily other parts of the emu (GE, GPU).
|
||||
The savestate format is changed, but from now on it is in principle more resilient
|
||||
(though it will continue to break as we tinker with the internals) [zeromus]
|
||||
- Remove 16MB of WRAM at 0x01****** from arm9. Mapped to unused instead. What was this? [zeromus]
|
||||
- Add RTC implementations (not fully) [CrazyMax]
|
||||
- Add a GUI hud system; start adding some HUD elements
|
||||
- Add functions for a lid open/close. Holding key (default "Backspace" in Windows port) while game is freeze/non freeze. [CrazyMax]
|
||||
- Added a bunch of crazy templates to the cpu and mmu for minor speed boosts [zeromus]
|
||||
- Add secure area decryption from ndstool [zeromus]
|
||||
- change backupmem autodetection to catch more cases of unusual usage patterns [zeromus]
|
||||
- Fixed Thumb LDMIA (fixes ingame Dead'n'Furious) [shash]
|
||||
- Fix repeating DMA (fixes NSMB parallax BG) [zeromus]
|
||||
Graphics:
|
||||
- Added gfx3d module which emulates the whole GE as part of the core emu. [zeromus]
|
||||
- Moved the windows/cocoa OGLRender to the emu core and replace ogl_collector.
|
||||
Now every platform shares the same 3d code. [zeromus]
|
||||
- Reorganize 3d code to defer rendering to after 3d vblank. eliminates tearing, and texturing artifacts. [zeromus]
|
||||
- Add optional fragment shading pipeline for more precision [luigi__]
|
||||
- Many tweaks and improvements to 3d precision [zeromus, CrazyMax, luigi__]
|
||||
- Rewrite VRAM mapping control and rendering [CrazyMax, luigi__]
|
||||
- Improvements to 2d/3d compositing aiming at better NSMB rendering; still imperfect [zeromus]
|
||||
- Fix in capture display (many games with both 3D screen not blinking now) [CrazyMax]
|
||||
- Fix in master brightness (this is fix games with black screens) [CrazyMax]
|
||||
- Added SSE2 version for some matrix routines [CrazyMax]
|
||||
- Make matrix 4x4 multiply routines use W-coordinate. [zeromus]
|
||||
- Add many matrix and vector functions to matrix.cpp [zeromus]
|
||||
- Added transparency and fixed material alpha support and alpha testing on the 3D core [shash]
|
||||

|
||||

|
||||

|
||||

|
||||
- Toon shading system [luigi__]

|
||||
- Make GE matrix mult and load commands clear out unused rows and cols to identity correctly [zeromus]
|
||||
- Fix errors in matrix operations regarding projection mode and pos-vector mode [zeromus]
|
||||
- Fix error in command unpacking which caused some display lists to totally blow up [zeromus]
|
||||
- Convert alpha and material values from [0,31], [0,7] etc ranges to opengl [0,maxint] ranges in a more precise way [zeromus]
|
||||
- Add opengl state caching. This is of dubious performance assistance, but it is easy to take out so I am leaving it for now. [zeromus]
|
||||
- Add MMU->GPU signal for when vram mappings change, which allows it to assume textures are unchanged unless vram has changed [zeromus]
|
||||

|
||||
