GS memory is only 4MB but rendering is allowed to be 2048x2048
with 32 bits format (so 16MB). Technically the frame/depth buffer can start
at the end of the GS memory. Let's not waste too much memory.
Fix crash with BASARAX
(game draws a 2048x1664 32 bits area)
The hack only fix the HW renderer but not the SW renderer. However I'm not sure
the issue is from GSdx.
The hack will disable alpha test that used to generate empty draw call.
CID 146985 (#1 of 1): Uninitialized pointer field (UNINIT_CTOR)8.
uninit_member: Non-static class member vuxy is not initialized in this
constructor nor in any functions that it calls
CID 168623 (#1 of 1): Missing break in switch
(MISSING_BREAK)unterminated_case: The case for value
GS_VideoMode::Unknown is not terminated by a 'break' statement.
Manual gives all setup to upload a palette from the host. But nothing forbid to render
directly in the palette buffer. (GS rule nb 1, there is no rule ^^)
Fix Virtua Fighter 2 dark colors
However I'm not sure we can fix HW renderer. Rendering is done on the GPU but palette
handling is done on the CPU... So we need to read back data (ouch, and slow). A quick
test didn't get the expected results. Potentially there are others bugs (aka not gonna
happen on the HW renderer)
IOCTL_CDROM_RAW_READ apparently does not work for some read modes on
some optical drives, which makes some CD-ROM games unplayable from the
disc.
Work around the issue by using SPTI to retrieve the raw sector data. The
old reading method has been retained in case SPTI cannot be used (if the
device could not be opened with write access).
Fix motocross mania missing texture. Close#1319
As far as I understand, transfer is initialized in DIR. But the real
write only occured later so the blit buffer could have been overwritten
by a new value.
BLIT 0 13700
TREG 40 40
DIR 0 0
BLIT 0 13f00 <=== the bad guy
Write! ... => 0x3f00 W:1 F:C_32 (DIR 00), dPos(0 0) size(64 64)
v2: set a value in m_tr.m_blit for load state
It creates a regression on game that uses a small temporary target to
upload textures of various sizes. Inital code was done to handle direct
frame write (background, FMV) so big target
Purpose is to control the filtering when final image is displayed on the screen
Could improve the sharpness of the output in some games (ofc, it will be pixelated)
When depth primitive is constant and depth test is greater or equal, we can
execute the depth write after color (depth status will only depends on the initial
value)
New case for RGB_ONLY ate:
If the blending equation uses a fixed alpha or a source alpha. We can postpone the alpha write
in a 2nd pass.
If depth can also be postponed, we can guarantee the order of correctness of the value.
1st pass => do RGB
2nd pass => do Alpha & Depth
It fixed Stuntman letter rendering :) Remaining of the game is still broken :(
PCSX2: IPU end of video freeze fixes
Fixes end of video freeze in Enthusia - Professional Racing.
Fixes end of video freeze with IPU Normal error in games like Enter The Matrix(#1494), Rygar, Freestyle Metal X, etc. Also fixes The Incredible Hulk and Bolt (thanks to @prafullpcsx2 for testing).
