- Fixed up color offset register support for new 2D rendering system. Now maintains 2 computed palettes for layers A/A' and B/B'.
- Fixed a minor bug in InitPalette(); VRAM was not being typecast properly.
- Fixed specular lighting bug that occurred on some OpenGL drivers because integers were not being interpreted as floats in the vertex shader.
- Began to update copyright date in some files.
- Graphics modules now use the C++-style names for C standard library headers (e.g., stdio.h -> cstdio) consistent with the rest of Supermodel.
- Added multi-texture fragment shader to repo.
- Added a multiTexture option (enabled by default) to use multi-texturing to decode textures.
- Added some comments regarding timing to the PowerPC execution loop.
- Added support for layer priorities. Highly unoptimal! This absolutely needs to be polished up before any release (and properly documented). For now, priorities in the popular games seem to be fixed but not all possible priority settings have been figured out yet.
New gpuMultiThreaded config option to enable/disable multi-threaded rendering (enabled by default, disabling it reverts to previous behaviour).
Other rendering optimisations:
- texture uploads now only affect appropriate region in the texture sheet, rather than uploading the whole sheet each time
- performance of clearing the model caches has been improved
New Alt+O key input added to toggle outputting of frame timings for debugging purposes.
- Moved Logger.h to OSD/, cleaned up comments.
- Command line and config file parsing have been rewritten.
- Began replacing C standard library headers with C++ versions (eg. stdio.h -> cstdio). I think I got most of them, but not all.
- CSoundBoard is not derived from CBus.
- Optimized sound board memory handlers (now using switch statements).
- Added DSB emulation (based on R. Belmont's M1 source code).
- Improved ROM loading: only unique ROMs (those not shared amongst games) are used to identify games. The ROM loader will no longer get confused as easily.
- General cleanup here and there, removed unused Render.h file.
- Model LUT now capable of differentiating between texture offset states (linked list of different texture offsets for each model address).
- Removed texOffset uniform attribute from vertex shader -- no longer needed.
