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.
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
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.
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.

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.
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.
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.
Passes the merged output circuit as the base size for texture cache scaling code. Helps fixing scaling issues where games use both of the output circuits for rendering.
Future Note: Alter the behavior of IsEnabled() check always preferring the second output circuit for some weird reason. I plan on changing it to a better auto-output circuit selection mechanism but that could probably be done some time in the future.
JMMT uses a bigger display height on NTSC progressive scan mode, which is not really unusual hence adjust the saturation hack to only take effect on interlaced NTSC mode.
However, the whole double screen issue on FMV still exists. As a bit of information, this game has the second output disabled but seems to have some valid data inside of it, maybe the second output data is leaked into the first one? most likely a bug in the frambuffer data management rather than a CRTC issue (needs to be investigated)
The main FindMinMax methods is perf critical so instead I created a separate function
to ensure the constness of the depth
Fix letter regression on Xenosaga3
* Explicitly cast w_pages and h_pages into uint32.
* Prevent signed/unsigned comparison by converting lod into unsigned integer, honestly how coud a mipmapping level be negative?
Fix Berserk #1526 Well done guys but we're more clever than you ;)
So instead to mask the color channels as any guy that RTFM, they decided to use the illegal 8H frame format
* Always do +1 before the draw call
* Prefix texture name with i (as input) to keep them before the FB
Goal is to ensure that all renderers share the same draw call value.
Game: harley davidson
* write tex0 ctx0
* write tex0 ctx1
* draw ctx 0
Previous GSdx behavior will load the clut every write of TEX0. In the
above case the draw will take the wrong clut.
To be honest, it could be a wrong emulation on the EE core emulation.
The hardware likely got a single clut (1KB cache is quite expensive)
So clut loading must be skipped if the context is wrong.
Next draw will use the ctx1 clut so I apply TEX0 when the context is switched
Please test harley davidson :)
v2: detect context switch from UpdateContext function
V3: always set m_env.CTXT[i].offset.tex, avoid crash (Thanks to FlatOutPS2 that spot the issue)
V4: move bad psm correction code (rebase put it in the wrong place)
It impacts all renderers. It ought to fix issue in GTA radiosity,
Shadows in Jak series. (note shadows will suck in upscaling)
Implementation is really brutal. Expect a massive slow down, but at least we can test the effect
easily.
Normally perf impact will remain reasonable if the game doesn't use a Read-Write effect
Performances number are welcomes (my guess is really awful in HW mode, slow in SW mode).
You can enable it with "UserHacks_AutoFlush = 1"
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
Extend GSVector to support float move
Initial code likely used integer move for performance reason. However due to
the nan correction, register is now in float domain.
