Meta: gsdx CRC hack level

[gregory38]

OpenGL is able to emulate various draw call correctly. Here a list of games that still have CRC hack enabled at the partial (aka openGL) level. Goal is to monitor/test which game still require a CRC even for openGL.

Alpine Racer 3 still needs it, as the issue affects all renderers(I do know a solution, though it might be a bit hacky).

[gregory38]

Ok. If you have some explanation of the issue it would be a nice addition.

[FlatOutPS2]

https://github.com/PCSX2/pcsx2/blob/master/plugins/GSdx/GSRendererOGL.cpp#L700

If you add this if statement not just to the accumulation_blend, but in general it fixes the issue(the black mess, but it still removes the shadows like the CRC hack). A similar solution also works for DX9 and SW mode.

[FlatOutPS2]

The Burnout games hack is also still necessary for all HW renderers. They still have have the vertical pillars on the screen without the CRC hack.

What does CRC hack in Captain Tsubasa and DBZBD3? I always played Capitan Tsubasa without any CRC hack and didn't see any graphical errors.

[gregory38]

Captain Tsubasa Dunno, it seems to remove the drawing of 1 framebuffer. Need to check the history. Likely useless

DBZBD3 Complex CRC hack but actually most of it is already removed on the openGL level. I think this one is still active (need to search on the forum, or was it the DBZ2)

[gregory38]

For the record, the start of the outbreak ;) https://github.com/PCSX2/pcsx2/commit/13df336966c08780f948b7e03add79c9037434d7

You do know that CRC hack means the CRC Hack Level in the GSdx Plugin Settings menu? If that's set to anything above none(or possibly minimal), the CRC hack is always on.

Yes I know. I play with settings none (debug).

Turning it on at any level breaks more of Ace Combat 4 than it fixes. On fixes the weird ghosting effect, but removes the HUD in night missions.

[gregory38]

Ace combat gets 2 hacks actually. Maybe one can be removed. The ghost effect could be the blur comment. If someone can compile to test it, it would be nice.

        if(fi.TME && fi.FBP == 0x02a00 && fi.FPSM == PSM_PSMZ24 && fi.TBP0 == 0x01600 && fi.TPSM == PSM_PSMZ24)
        {
            skip = 71; // clouds (z, 16-bit)
        }
        else if(fi.TME && fi.FBP == 0x02900 && fi.FPSM == PSM_PSMCT32 && fi.TBP0 == 0x00000 && fi.TPSM == PSM_PSMCT24)
        {
            skip = 28; // blur
}

[FlatOutPS2]

I don't know what the clouds hack does, because the clouds are missing in HW regardless of CRC hack setting.

The blur is fixed by the CRC hack. Though the ghosting around the blur effect of the plane can also be resolved by setting blending unit accuracy to basic or higher.

But regardless of the blur, the entire plane of the player remains black regardless of CRC hack setting (see my issue on the bug: https://github.com/PCSX2/pcsx2/issues/1547 )

But as Cobra84 said, it causes issues with the HUD, though not just in night missions( see my test report: http://forums.pcsx2.net/Thread-Ace-Combat-Distant-Thunder-SCES-50410-E )

[FlatOutPS2]

The Getaway Black Monday is a complete cluster ****. It has effect on the cutscenes, but only seems to affect D3D modes. Turning CRC hack off makes the entire screen overly bright. setting it to Partial makes the screen turn green(and still too bright), and setting it to Full causes all kind of small opaque squares and white vertical lines appear over the effect, and the brightness is reduced too much(there is an effect during the cutscene to make the scene brighter, looks correct in SW).

With OpenGL HW the scene brightness sometimes appears correct, but there is a lot of flickering and a half-screen issue regardless of CRC setting...

[Cobra84]

The blur is fixed by the CRC hack. Though the ghosting around the blur effect of the plane can also be resolved by setting blending unit accuracy to basic or higher.

Blending unit accuracy has no effect on missions where the HUD also disappears with the crc hack.

[MrCK1]

Doesn't GT4 use CRC for brightness hack; or was that only DX?

[FlatOutPS2]

Blending unit accuracy has no effect on missions where the HUD also disappears with the crc hack.

BUA only removes the blurring. It doesn't affect anything else.

@MrCK1 GT4 isn't part of the checklist in the OP, as it has already been moved to the Full CRC level.

[Cobra84]

BUA only removes the blurring. It doesn't affect anything else.

I meant that the BUA doesn't fix the blurring in the same missions that are affected by the crc hack. It works fine in missions where the crc hack worked too.

[FlatOutPS2]

Please move the ResidentEvil4 hack to Full level. The CRC hack removes the fog, without the hack the screen turns green with D3D,, but the fog emulates correctly on OGL with hardware depth.

[mirh]

Actually.. I think AC, should need an additional hack too. Clouds are "tinier" in hw mode.

[FlatOutPS2]

Most clouds are actually invisible in HW in all AC games. The AC games need less hacks and more proper solutions. The current CRC hacks cause worse issues than they solve.

[mirh]

Isn't there like.. Just a single one? And only in AC4? Indeed, I usually play with them disabled ("None") given I seem to gain some fps.

Afaik AC only had COP2 patches.

[FlatOutPS2]

AC4 actually has two CRC hacks, and they both cause very annoying HUD issues. Anyway, a proper solution would probably work better than CRC hacks in this case.

[gregory38]

Could someone test those games

• FFVII DoC
• star wars force unleashed
• devil may cry 3
• eternal poison

[lightningterror]

Resident Evil 4

Seems Direct3D doesn't require any crc hacks anymore. Tho I recommend moving them to Aggressive since having those effects not emulated provides a nice boost.

Comparison (CRC level: None):

D3D

OpenGL

The fog in the distance is related to Depth Emulation, similar to dbz bt3.

Upscaling causes pixel offsets but can be fixed with Wild Arms Offset hack.

[FlatOutPS2]

TimeSplitters 2 CRC hack removes 4-player overlay from screen as it appears even in single player. It affects all hardware renderers, though only OpenGL renders it properly.

[13xforever]

Sakura taisen has issues with opengl hw renderer, details are in #1919

[MrCK1]

@lightningterror This list has become somewhat outdated. Can you check off any of the CRC hacks from this last that you removed previously?

[lightningterror]

@MrCK1 DBZ BT3 still needs crc hacks for both renders.

GT4 isn't part of the checklist in the OP, as it has already been moved to the Full CRC level.

And now it's on the Aggressive level since Texture cache has been updated.

[lightningterror]

Added Street Fighter EX3 to the list. https://github.com/PCSX2/pcsx2/pull/2123

[marcoluc97]

Sorry to bother but this Issue can still be used to check if everything is moved to GameDB and the related CRC hacks are purged?
