Code of RdpUpdate::update is based on angrylion's rdp_update().
Main visible difference: VI cuts several pixels on left and right of original image.
Cite from angrylion's commit message:
"rdp: new tests revealed the shocking truth:
the VI aggresssively and regardlessly of any data alignment specificities
cuts off either 7 or 8 pixels closest to h_start and h_end, so that nothing
ever appears on the screen unless (h_end - h_start) is 16 pixels or greater
(this removes marginal garbage graphics on the far right in Mario Tennis,
Turok 2 Seeds of Evil intro and probably other games)"
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.
When N64 game needs to apply frame buffer texture to a polygon, it
copies part of frame buffer data to texture memory. The plugin
does not copy frame buffer texture, since frame buffer texture already in video memory
and thus can be used directly.
However, sometimes polygons with frame buffer texture use texture coordinates wrap.
Wrap can't be done correct when whole frame buffer texture is used.
Thus, frame buffer subimage copy is implemented. Part of texture copied to
a new texture, which can be correctly wrapped.
