Add hidden option "UserHacks_DisableNVhack" to disable
the Nvidia hack on Direct3D which added black lines on the right
and bottom of the screen. Could be useful for Intel and AMD GPUs.
A better solution would be to add Vendor Id detection instead,
but this will do for now.
To disable the Nvidia hack add UserHacks_DisableNVhack=1 in GSdx.ini
Fixes glitchy water in Rogue Galaxy in Direct3D when the hack is
enabled.
Fixes Test Drive car reflection in Direct3D when the hack is enabled.
OTher games are affected as well.
For some CDs (i.e. Suikoden), trying to read a 2048 byte "cooked" sector
does not work. However, reading the raw sector and then extracting the
required 2048 bytes works fine, so let's do that.
This also makes it easier to port CD/DVD disk reading to operating
systems that don't provide CD/DVD interface conveniences.
Adds automatic HW mipmapping support.
It relies on CRC ids so if a game does
not have their CRC id but needs mipmapping
it will not work until the id is added.
Add GUI menu and tooltip for Automatic mipmap
"Automatic (Default)"
This option will be default option from now on.
Rename "Very Slow" text option to "Slow" for full mipmap
as it caused the text not to fit properly in the menu.
Credits also go to @RedPanda4552 and @ssakash for helping
with the code.
Rearrange the two columns of HW hacks, new arrangement
is done in alphabetical order on Windows and Linux.
Rename some hacks on Linux to match the windows version.
Some other minor tweaks as well.
The following patch grays out the configure button when there's no
configuration dialog available for the selected codec. What's the use in
clicking it when no dialog pops up? :P (I've been tricked by it lots of
times)
Add HW Hack that enables Framebuffer Conversion on the CPU instead of the GPU.
Can fix broken textures on games but at the cost of slower performance.
List of games: Harry Potter games, FIFA Street games.
Games like Call of Duty, Kung fu Panda might also be affected as well as others
especially on Direct3D.
Add HW Hack GUI option on Windows/Linux for 4-bit and 8-bit Framebuffer conversion hack
named "Frame Buffer Conversion".
It's not really used, and the OSD uses a different API.
The specified calling convention (stdcall) is also incorrect since
variadic functions are caller-clean, not callee-clean. The compilers
ignore the stdcall and just use cdecl (I think), though it does trigger
a -Wcast-calling-convention on clang.
The wrong comparison was used, so all the relative offsets were
completely wrong. Fixes the wrong track issue in the CD player.
Regression introduced in f314c2a4d9.
Regression was introduced in #1954
GSdx caused the emulator to crash when the renderer was restarted.
It may have affected older gpus from nvidia/amd
with older OpenGL support as well.
The swap interval function must be called on the same thread that
rendering takes place on. This fixes an issue where the turbo speed and
frame limiter hotkeys fail to disable vsync when the OpenGL renderer is
used.
Using range loops where possible (correctly).
Using auto where possible (minimize code changes whenever it's decided to change back to a std container).
Use more efficient erase pattern (where possible).
Minor code tweaks.
PCSX2 sends a negative value (-1) to GSdx when adaptive mode is
specified for Vsync, this mode is exclusive to OpenGL at the moment
and is unimplemented on the D3D11 renderer. Also the present function
of swapchain only accepts values from 0 to 4 as parameter, hence
passing negative values to the function is undefined behavior.
So let's fallback to standard synchronization method on D3D11 when
PCSX2 requests for adaptive mode.
Fix CRC hacks on PAL version.
PAL version will no longer experience very high brightness/contrast
issues on stages in hw mode caused by an incorrect CRC hack.
Moved a CRC hack back to OpenGL mode only for the PAL version
because texture shuffling does not work properly on PAL games.
Kung Fu Panda becomes stuck at an autosave warning screen since it
cannot detect button presses correctly. This fixes the issue, though
potentially it may negatively affect some other games (see #1831,
unfortunately no game titles weren't mentioned).
The issue was introduced in commit 3075ec2203Closes#1965.
Forgot to replace `IDC_TEXT` with `IDC_VALUE` macros, due to this the
text containing the name of the options was being updated with the
current value of the option instead of updating the text designated for
holding the values.
DBY isn't an offset to the frame memory but rather an offset to read
output circuit inside the frame memory, hence the top offset should also
be calculated for the total height of the frame memory. Fixes software
mode regression in Beyond Good and Evil.
Also handle cases when GetFrameRect() is called without any paramerer to
avoid an illegal value access violation on the DISP register.
output 1 strip of 2 triangles instead of 2 strips of 1 triangle.
Potentially it would reduce the geometry shader overhead. And it
might avoid a middle line in sprite in some AMD GPU/driver/OS
bad combination
SDL doc:
"Mappings not belonging to the current platform or with no platform
field specified will be ignored (i.e. mappings for Linux will be ignored
in Windows, etc)."
Issue #1978
GSdx-ogl: Console messages v2
Follow up to
commit/ec63b04719fd9c05a6aeeacb55dc1c54f5ef145b
Add intel broken driver wiki link message in console (OpenGL).
Print intel / amd buggy driver message once in console (OpenGL).
Pring texture barrier and viewpoint array info once in console (OpenGL).
Enables character outlines to partially work on Full CRC.
DX9 has a small issue where a small black line at the bottom shakes when outlines are enabled.
You can either use Aggressive crc or x,y offset to fix the issue.
Removed unnecessary crc hack that caused shadows on stationary objects (trees) to move on Direct3D in a weird
motion blur type way when the player moved slightly.
* Cast return value of IsEof() to bool. (Avoids int -> bool performance
warning error)
* Cast field and index to the required parameter type of AppendRawData.
The sprite geometry shader was still being used even if the sprites were
converted on the CPUs.
Convert all sprites using the GPU - the fix isn't ideal, but it'll
likely have to do unless someone feels like porting over more of the
OpenGL changes to the D3D11 renderer.
Closes#1921.
Class member variables are initialised in order of declaration in the
class definition. Move native_buffer to the top of the class definition
to avoid initialising m_width and m_height to random values.
Move the custom resolution scaling code to a separate subroutine and
allow future RT buffer resize calls when the buffer size isn't enough.
(Example: when a game's CRTC/Framebuffer size changes. The older code
didn't consider such cases)
Added a more robust buffer size calculation mechanism for custom
resolutions. Improves performance in higher resolutions for games
which don't need a big buffer. There's a great boost in performance
at GS limited scenarios.
I don't even feel there's a need for the large framebuffer option right
now, For future - I plan on making the large framebuffer enabled version
as the default as the overhead is there only at situations when it's
necessary. Until then keeping the original code just to be on the safe
side in case any issue pops up.
An EOF only occurs after attempting to read past the end of the file.
Account for this correctly, which fixes a potential infinite loop when
reading back an xz compressed GS dump.
Add the bitfield structure of the undocumented SYNCV register,
potentially might be useful in proper height determination of the output
circuit for some weird games which still get it wrong but still haven't
figured out how it might be useful. Maybe some sort of black magic
formula with the vertical synchronization values?
The differential phase value seems to closely resemble the display
height value of the video modes (480 for NTSC, 576 for PAL) but after
some investigating into the differential phase, I have no clue on how
they might be even related. Hopefully the mystery will be unveiled in
the near future.
Reduce disk space. Easy to share.
It would be nice to port the code to Windows.
libzma code was taken from https://git.tukaani.org/xz.git
Note: only short dumps are supported so far. Big dump will freeze the interface during the compression.
Or will suck all the RAM.
Note2: a multithreaded encoder would badly impact the compression ratio
Thanks to Turtleli for all review comments
* replace gtk_table by gtk_grid
=> it still misses some paddings
* Use 3.22 monitor API to query screen size
=> need to be tested
* directly add scrolled windows into a container without bothering with
the viewport.
Code compile fine but wasn't tested.
v2: disable the code until I (or someone) get a chance to test and fix it.
Thanks to @colepcsx2 (https://github.com/PCSX2/pcsx2/pull/1896#commitcomment-21858717) for pointing it out!
I also updated the prefix in the inferior video mode detection of GSdx, I'm not even sure why we need the videomode info on the plugin side, might be useful someday.
The shadeboost options text (Contrast, Brightness, Saturation) were not
grayed out when shadeboost was disabled, it was sort of inconsistent
compared to the behavior of external shader, so added grayouts to them
when shadeboost is disabled.
Also changed "OpenGL Very Advanced Custom Settings" to "OpenGL Advanced
Settings", the verbosity didn't help much in my opinion.
Initial plan was to allow to remap the logical (SDL) key.
Unfortunately I feel some issues with the current enum.
* button/axis overlap
* trigger/axis must be handled differently
Nevertheless, code is easier this way
SDL_GAMECONTROLLERCONFIG is nice but limited to a single entry. (Note it can still be used)
Option name is SDL2. Here an example
SDL2 = 03000000a306000020f6000011010000,PS2700 Rumble Pad,a:b1,b:b2,back:b8,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,guide:b12,leftshoulder:b4,leftstick:b10,lefttrigger:b6,leftx:a0,lefty:a1,rightshoulder:b5,rightstick:b11,righttrigger:b7,rightx:a2,righty:a4,start:b9,x:b0,y:b3,platform:Linux,
Split code in 2 parts
* Base class (GSWndEGL) that implement the core EGL and GL context
* Derived class (GSWndEGL_X11/GSWndEGL_WL) that implement the backend to handle native resources
Note: Most backend code is only useful for GSopen1/PS1 mode. GSopen2 only requires
the AttachNativeWindow implementation
Code is based around EGL_EXT_platform extension that allow to select the platform at runtime.
Note: I think the extension was integrated in EGL 1.5
The X11 backend was mostly converted to XCB
The wayland backend is only a placeholder for future code
I don't know if MS windows is/could be supported with EGL_EXT_platform API
Code validated on Mesa. Proprietary drivers aren't yet tested.
* prefix remaining member with m_
* Use array for m_effect_id
* Properly Destroy/Close Haptic/Joystick/Game Controller
(except on older SDL versions which are buggy)
Initialise pointers to nullptr, move the LoadLibrary code into the try
block (where it should have been in the first place), and use Close()
to cleanup if an exception occurs. Also initialise/destroy the critical
section in the base class constructor/destructor.
This should avoid resource leaks if an exception occurs.
Instead of creating a separate message function, just reuse what() and
pass the string to the std::runtime_error constructor instead.
Also catch a reference to a std::runtime_error instead, since it'll
allow for simpler cleanup.
Moved a CRC hack to Aggressive that can cause or fix VRAM and RAM spikes.
This way people can switch between each config if they experience problems with either.
Varies on userconfig , game version and maybe hardware.
Added missing CRC game version for GT4 pal.
Note: The issue might be the same on GT3 and GTConcept , the code might
need to be removed for those games as well.
Hack was used to remove garbage data rectangles from popping up on screen when objects and characters were added to or removed from the world.
This issue is now being handled by OI_DoubleHalfClear in GSRendererHW.cpp, so the hack is no longe necessary and has been removed.
Moves Resident Evil 4 hack to Aggressive level as it is no longer
required to fix any issues, but does offer a decent speed boost.
Moves The Getaway & The Getaway Black Monday CRC hack to Full level, as the issue can be resolved
when using the OpenGL Hardware renderer.
The legacy version is the version 1.3
The new version is the version 2.0. It would be based on SDL2 only
Distribution information.
If you link wxWidget with SDL, you will need to be sure it is SDL2 or upgrade.
You can build wxWidget with SDL2 with the following trick
export SDL_CONFIG=/usr/bin/sdl2-config
./configure --with-sdl .....
* Windows behavior must be checked
* remove glsl_source.h
v2: fix missing include
Big thanks to Turtleli
v3:
fix indentation in gsdx-res.xml
add dependency in cmake
remove old res/glsl/fxaa.fx symlink
add tfx.cl for OpenCL support on Linux
v4, v5
fix cmake indentation
It is done automatically on Linux. Strings are much
better with this NULL char ;)
All credits go to turtleli
v2: increase resize instead of push_back NULL char
add checkboxes for the 2 "new" hacks
Wrap gs memory & merge postprocessing sprite
add tooltip for OpenGL options
v2: based on turtleli feedback
use gtk_scrolled_window_set_propagate_natural_height on GTK 3.22+
use the nicer GTK_CHECK_VERSION macro
Move GL_ARB_copy_image to optional for OpenGL SW render.
It will allow Ivy Bridge to work with OpenGL SW as it's not required.
Sandy Bridge is not yet tested , would be nice if someone could test.
Clip Control is only used for the HW renderer.
It will help Nvidia DX10 GPU on Windows. Potentially old AMD GPU too.
Unfortunately Ivy bridge still misses texture copy
Note on Linux, you can use the free Mesa driver.
Otherwise, it is time to save money for a future upgrade :)
Adds merge sprite hack to GSDx hacks dialog
And ports merge sprite hack to Direct3D renderers.
Special thanks to my keyboards Ctrl, c and v buttons for all their hard
work in porting this hack.
Ports the "Unscale Point and Line" hack to the Direct3D11 Hardware renderer.
And enables the "Unscale Point and Line" hack for Custom Resolutions with Direct3D11 and OpenGL.
Adds Windows GUI elements of the split texture filtering options.
Bilinear Texture Filtering is moved to the top section of the main GSdx window,
and Trilinear Filtering is moved to Hacks.
Adds Texture Filtering Of Display option to the Shader dialog window Windows UI.
Updates the layouts of the Shader and OSD dialog windows to more closely resemble the Linux GUI.
Reorganizes Hacks dialog window.
Adds UI elements for the Memory Wrapping and HPO v2/Special commits
Adds advanced OpenGL functions "Geometry Shader" and "Image Load Store" to the Windows UI.
Renames "Configure Hacks" to "Advanced Settings and Hacks", to more closely resemble the Linux GUI.
Adds GS Memory Wrapping hack to Windows. Enabling the hack will fix cut-off cutscenes in Wallace & Gromit: The Curse of the Were-Rabbit and Thrillville.
Ace Combat 4 CRC hack removes clouds for a good speed boost, which removes both 3D clouds(invisible with Hardware renderers, but cause slowdown) and 2D background clouds.
Removes blur from player airplane.
This hack also removes rockets, shows explosions(invisible without CRC hack) as garbage data, causes flickering issues with the HUD, and in some (night) missions removes the HUD altogether.
The CRC hack has been moved to the aggressive level.
Aggressive is misspeled several times in the file, this has been adressed.
Changes to the dependencies of the generated logo files did not trigger
a rebuild of the files. Use add_custom_command instead of
execute_process so build dependencies can be specified.
Also prevent the generated files from polluting the source directory.
The pixdata format loader has been removed from recent versions of
gdk2-pixbuf, so the logo doesn't load. Avoid preprocessing the data and
leave the logo as an embedded bitmap file.
Allow the output circuit saturation to take place at cases where one of the output circuit is enabled with frame mode rendering, I'm not sure it would be safe to allow saturations when both of the output circuits are enabled with frame mode rendering. Unlike field mode rendering, frame mode doesn't use identical rectangles at same co-ordinates for output in two alternating fields and potentially they could use a much bigger output size when both of the output circuits are enabled and are separated without any intersection. So let's limit the saturation to only the cases where we detect a single output circuit for frame mode rendering.
Fixes a regression in Devil May Cry 3 and Sky Gunner.
If a user switches renderer they also have to remember to change the CRC
hack level for the best user experience with the selected renderer.
This commit adds a new automatic CRC level that autoselects the
recommended CRC level for the selected renderer, so that a user doesn't
have to make the change manually.

If OpenGL software is the saved ini renderer and F9 is pressed to toggle
to the hardware renderer, depth emulation will be disabled. This fixes
that issue.
GSdx ogl: SSO Workaround for AMD buggy drivers
All 2017 drivers are now blacklisted.
The BSOD/crash issue is still there so don't set Blending Accuracy to None!
Shortened the message in the console making it more appealing.
-1 is only returned when there is an encoding error, and the va_list
argument is indeterminate after being passed to vsnprintf.
Use the return value to determine the buffer length, and call va_end and
then va_start before vsnprintf is called again.
Some general fixes and UI improvements.
Adds Reset Configuration to Input/Force Feedback configuration screens that resets the configuration for the selected control(s).
Adds Restore Defaults button to the General tab that deletes all LilyPad
Settings and bindings and resets to the default settings.
Adds double-click functionality to the PAD list on the General tab,
which will now send the user straight to the corresponding PAD tab.
Fixes issue where losing focus after pressing alt-tab would end up
blocking the F4 button (which is used for turning the PCSX2 FrameLimiter
on and off).
Fixes: https://github.com/PCSX2/pcsx2/issues/1797
Adds quick setup that allows for quickly setting up all the default pad
buttons without having to click on each one separately.
Hides special inputs(inputs that aren't available on a PS(2) controller) by default.
ICO uses a depth of field effect for the fog. Depth is extracted
into the alpha channel of a texture. And then used as blending factor.
You need a 1:1 texture/pixel mapping otherwise you will line at boundaries.
In order to extract the DoF, ICO moves the depth buffer around the GS
memory. Memory moves are implemented in the not-scaled world. It means
that we can't have the above 1:1 ratio. And we don't know anymore that
data are coming from the current depth buffer.
The solution: I reused an HLE channel shader to read the depth buffer directly.
This way I have the guarantee that pixel/depth are aligned.
Close#1816
Otherwise you have a write before read typical race condition. It works
most of the time because textures are stored in temporary buffers (aka
texture cache). So the race condition requires texture invalidation in the mix.
I hope the perf impact will be small enough.
Fix#1691
Blood Will Tell: gray scale effect description
Frame is renderer in 0x700
Sync 0x700 (RT will be used as input)
Foreach page of frame
// The missing Sync was this one. You can't copy new data to 0x2800
// until you finish the rendering that use 0x2800 as input texture
// (AKA end of this foreach loop)
Sync 0x2800 (not the first iteration, texture will be used as a RT)
Copy page from 0x700+offset to 0x2800
Sync 0x2800 (RT will be used as input)
Render Effect line1 from 0x2800 to 0x700
Alpha test should only be disabled when writes to all of the alpha bits in the Framebuffer are masked. Fixes a regression in Dragon Ball Z: Budokai 3 scouter image rendering.
It allow to do the division before the size multiplication
It avoid a float overflow if T is too big.
Old behavior: (T * size) / Q
New behavior: (T / Q) * size
Performance Note:
* Rcp was replaced by a slow division (more accurate)
* At least we avoid a 2nd loop on the vertex buffer
It helps on Pro Soccer Club and Galerians Ash rendering
Tric Note:
SPRITE must be handled differently because the 'q' of first vertex could
be invalid
Bilinear applies to all renderer
* Common code done in GSVertexTrace
* Extend it with forced but sprite (trade-off between linear/upscale glitches)
* Linux GUI option was moved at the top with the renderer selection
Trilinear is moved to OGL hack
close#1837
Thanks to Flatout for the review and feedback.
It will take care to update the Window GUI :)
Fixes "project out of date" issue for wx_config on VS2017.
Fixes whole program optimisation possibly not being applied on release
builds for USBqemu (it may have been applied, but I can't actually tell,
and now it at least shows properly in the VS property editor).
Typical bug, missing/wrong texture on the SW renderer but working fine on the HW renderer
Debugged on ATV Quad Power Racing 2 but I suspect couple of game are impacted
Bug description:
GSdx flatten the Q value of sprite. So m_vt.m_eq.q is true when Q(2N+1) are the same.
Q(2N) values could be random. The fix replaces Q0 by Q1 for the uniform Q value.
Previously, the NTSC saturation was also applied for double scan mode (Interlaced and Frame) where the developers send double the height to the DISP registers, saturation shouldn't be performed at such cases as the developers could send a value of 780 while the real size of the output would be 390 due to double scan mode. Doing the saturation later after identifying the real size also seems a bit counter-intuitive as we haven't discovered any cases where double scan games require the NTSC saturation hack. So let's just apply the saturation only for Interlaced (Field) Mode and omit the saturation step for other modes.
Isolate all the hacks into a separate subroutine and properly document about them, should make it easier for people to understand the display rectangle setup code, the hacks were totally messing up the readability of the function earlier.
The buffer contains extra room to avoid a segmentation fault due to an overflow.
Unfortunately the end of the buffer wasn't initialized which can lead to unexpected behavior.
Based on issue #1806 it could impact Guilty Gear X2
Mesa AMD was updated :)
all drivers[1] that support GL_ARB_shader_image_load_store got GL_ARB_clear_texture
[1] Intel driver misses others extensions to run GSdx
Rendering will be corrupted (for advance effects) if the driver doesn't support it.
However it allow to run with Mesa software emulation (or inside a virtual machine)
Note: mesa still requires an override of the buffer storage extension
MESA_EXTENSION_OVERRIDE=GL_ARB_buffer_storage
Previously, the combobox will reach an indeterminate state whenever it's passed with a value out of range via ComboBoxInit(). To avoid such cases, let's initialize the current selection of the combobox with the front element of the settings vector whenever we detect an out of range value which is not declared in the vector.
To reproduce the issue, set "Renderer" to some sort of crazy value like 50 in the GSdx.ini file and it'll mess up the whole GSdx plugin dialog really bad. This patch prevents such undesirable behavior by simply selecting the front element in the vector when we read an unsupported value.
Previously, the auto output circuit selection of the GSdx wasn't good, it simply defaulted to the second output circuit even when the first output circuit is also enabled. The new algorithm for auto selecting returns the merged rectangle dimensions when both of the output circuits are enabled and if the condition for merge is not satisfied then it returns the bigger output circuit.
The "L3 Toggles Turbo" hack has been removed and been replaced by a
bindable Turbo button on the Pad tabs. The Turbo function in the input
configuration has been renamed Rapid Fire.
Removes Ignore Key(hasn't functioned since LilyPad 0.9.9 (PCSX2 0.9.6)),
and "Send escape on window close" hack (unnecessary for PCSX2 and caused
issues with other emulators).
This new option on the pad tabs disables an input so it will be ignored
when trying to bind another input. This is helpful when binding controls
for a device with an input that's difficult to center like an
accelerator, or just always active like a faulty button or analog stick.
I didn't fix all the warnings (purpose was to realign code with "recent" update)
Linux note: only miss 2 major items
* res/tfx.cl loading
* device descriptor
* And various bug fixes ;)
Previously, when F8 was triggered multiple times in a single second, the latest captured image would replace the previous captured one as it has the same name as the previous image.
The following patch detects such cases and adds a number along with the filename when new image capture is requested under the same time as the previous capture.
This reverts commit
d6383e6c21
It created a regression in Everybody's Golf 4/Hot Shots Golf 4, breaking the renderering when depth emulation is disabled/when using a Direct3D Hardware renderer.
The code is now a mirror of the ::add. So 1 insert == 1 erase
This way it won't crash on future update. And it will support future GS
memory wrapping improvement.
ZoE2:
RemoveAt overhead plummet to 0.5%. It was 17% !
However insertion is a bit slower. Due to the begin() after the push_front
v2: use std:: for lists and arrays
Removes Alpine Racer 3 hack. Issue has been resolved.
Moves NanoBreaker hack. Issue has been resolved for OpenGL and hack has
been moved to DX only.
Moves Tri-Ace games hacks. Hacks are also necessary for OpenGL with "Partial" CRC Hack Level to prevent massive slowdown.
Move Tales Of Legendia hack back as it's also necessary for OpenGL with "Partial" CRC Hack Level to prevent graphical issues.

Added PAL and NTSC-U CRC's for Ar tonelico II.
Unfortunately it requires at least GCC6. If a nice guy can check the generated code on GCC6.
I don't know clang status.
Here the only example, I have found on the web
https://developers.redhat.com/blog/2016/02/25/new-asm-flags-feature-for-x86-in-gcc-6/
Current generated code in GSTextureCache::SourceMap::Add
38b3: bsf eax,esi
38b6: add esp,0x10
38b9: test esi,esi
38bb: jne 387e <GSTextureCache::SourceMap::Add(GSTextureCache::Source*, GIFRegTEX0 const&, GSOffset*)+0x6e>
BSF already set the Z flag when input (esi) is 0. So it would be better
to not put a silly add before the jump and to skip the test operation.
OMG, Zone of Ender got a speed boost from 11 fps to 45 fps
Seriously, the goal is to allow benchmarking GSdx without too much overhead of the main renderer draw call
Note: unlike the null renderer, texture/vertex uploading, 2D draw, texture conversions are still done.
* move the post-processing frame into the OSD tab
* Rename Global Settings to Renderer Settings
* put monitor and indicator check box on the same line
At least we have a similar number of options by tab
This reverts commit f77c1900fa.

Another fix was done later for Jak cut scene (or FMV). One game got a regression (don't remember which)
It's only ever updated after the queue is updated, so its state will
always lag slightly behind it. It's sufficient to just use empty().
This seems to fix some caching issues that were noticeable on Skylake
CPUs (#998).
In the previous code, the worker thread would notify the MTGS thread
while the mutex is still locked, which could cause the MTGS thread to
wake up and immediately go back to sleep again since it can't lock the
mutex.
Use a separate mutex for waiting, which avoids the issue.
Some PSX games seem to store image data of the drawing results in an undeterminate area out of range from the current context buffer. At such cases, calculate the height of both the frame memory rectangles combined.
What happens on "Crash bash" -
* At first draw, scissoring is limited to SCAY0- 0 & SCAY1- 255
* At second draw, scissoring is limited to SCAY0- 255 & SCAY0-511
Previously, we limited the height to the value of one single output texture, so instead of that let's calculate the total height of both the two buffers combined to prevent such issues.
