Fixed Ogre Battle 64 Opening Splash Screens Flicker. #1868
Details
Problem: frame buffer end address set to minimal when buffer is allocated.
It is updated on next call of gDPSetColorImage.
In case of Ogre Battle 64 Opening next call of gDPSetColorImage occurs in next frame.
VI can't find the buffer because REG.VI_ORIGIN points on buffer with some offset,
which in this case is larger than diff between start and end address.
VI allocates new buffer, which eventually replaces the current one and flickering happens.
Solution: update current buffer's end address in gDPFullSync()
to ensure that it will be correct at the moment when VI will search for buffer to draw.
Remove Crop feature.
Change settings save-load when "per game settings" enabled:
* When config dialog opens, show custom settings for the running game. If no game run yet, show main settings.
* When user press OK button, save settings to the custom ini file and to the main ini file.
Fixed tripleplay2000: black background in game #346
Problem: The game allocates auxiliary buffer with the same width
as the main one. Plugin detects it as main buffer and set its width
and height as of main buffer. Actual buffer height is half of main
buffer height, but it became known only when game switches to the
main buffer. Wrong buffer height leads to wrong calculation of
buffer address space. Game uses textures with addresses behind
the actual buffer’s address space but within calculated one.
Plugin tries to use buffer texture instead and, as the result,
everything is black.
Solution: The situation is bad. Plugin cannot detect that
allocated buffer is an aux one. I decided to forbid buffer usage
as texture if buffer is new. New buffer is blank, so reading from
it is strange. N64 games do lots of strange stuff, so this solution
is potentially dangerous.
Fixed Nushi Zuri 64: fb background doesn't work anymore #1115
Problem: The game normally uses color and depth buffers.
When it needs to show rectangle with text, CPU copies current color buffer
by depth buffer address. This buffer rendered as background, text rendered over.
Plugin detects buffer usage and tries to use depth buffer as background texture.
That buffer in video memory has no color information, because data copied by CPU and contained in RDRAM.
Solution: check that found frame buffer is valid.
In this case validity check will fail because RDRAM content modified by CPU,
and background will be read from RDRAM.
