Onimusha: Dawn of Dreams SLUS-21180 (should work for both discs)
CRC = FE44479E
Improve menus, and other 2D displays handled on IPU. Not full fix, but really better than what we had before.

Code:
// Set IPU_DATA IVF to Intra
patch=1,EE,003BFDD8,word,3C040020

// Set IPU_CMD to IDEC, and set QSC to 2
// Why 2? Because it seems to work best.
patch=1,EE,003BFDEC,word,3C021002

// Old patch by shadow lady (still needed)
patch=1,EE,00104170,word,00000000

// Disable print - we need that loop!
// Without loop ipu break itself.
patch=1,EE,0010FDC8,word,34190180
patch=1,EE,0010FDCC,word,1720FFFF
patch=1,EE,0010FDD0,word,2739FFFF
patch=1,EE,0010FDD4,word,03E00008
patch=1,EE,0010FDD8,word,00000000

Kakutou Bijin Wulong (Japan) SLPS_256.57;1) Game CRC = 0x4A4B623A

another game that i think crc hack in PCSX2 is not required and can be removed with this code
crc hack level: "none (debug)"

Code:
//Excessive blur and misaligned effect removal test
//in HW 2x up enable "disable screen effects" (like crc hack) or better use next advice
//PCSX2 > Config > Video  (GS) > Pluging settings > "Enable HW Hacks" > Upscaling hacks > "half-pixel offset" to "Special texture" fix missaligment
//patch=0,EE,202255FC,extended,34020000 //disable screen effect - better no use
patch=0,EE,202257A4,extended,34020000 //blur a
patch=0,EE,20225A7C,extended,34020000 //blur main
patch=0,EE,20225CC4,extended,34020000 //blur a2

Sure, it will be nice if you can port it. No need to ask about something like that. Any patches posted here are public domain. 
Just fyi, patches for "Disable print" are not required to make things work, you can have the same effect if you disable "EE console" logging in settings. I applied it because i saw few users asking why is so slow. So i just removed that message that is constantly repeated in game code to avoid additional questions.

Silent Hill 2 (and SH2 DC)  PAL
Minor fix for graveyard movie, possibly for others. Works with and without Fast CDVD, also with and without Instant VU1 hack.
This won't work with MTVU, since it need more aggressive loop to delay RotateThreadReadyQueue, and that make movie choppy.

tested CRC hack Level=(None Debug)
another game i think crc hack level can be retired and reemplaced by this code, also i check this game will require "Instant VU1" (enabled by config default)
or some 2d art will show corrupted (tested safe mode, no codes)

X2 Wolverine's Revenge (NTSC-U)
Fix HW mode, not tested beside menus, and first level. For full compatibility, require Preload Frame Data.
crc=16FB9855
Code:
patch=1,EE,0017A5E4,word,3C07000F

Edit: Tested little bit more, and patch is broken, but maybe it will at least give some hint where to start if someone want to fix this.

ESPN International Track & Field (SLES-50036)
crc=E59E10BF
Prevent "Call stack overflow" when going ingame. Patch force wait before sending VIF1 DMA if ASR1 is not available. 
In some rare situations ASR1 never is set to zero, so if that happen patch force it to 0 after some wait. 
Minor issues with audience seems to be also vif issue, but that patch fix it only partially.

Street Fighter EX3 
Fix for missing effects in Hardware mode. Game use result from sceVu0RotTransPers as divider, so that create flt_max, and is send to STQ. Which later result in situation that current GSDX can't handle without losing some speed, or missing effect. Patch add 10000000 to vf10.x result which should be harmless for functions that use only lower bits. And that game seems to use upper bits only for problematic div.s. I tested game, and everything seems to work fine, but someone more familiar with this title should do more testing.

Saints Seinaru Mamono (NTSC-J), SCPS-15052, Game CRC = 0x7AC8A38D

This is just Primal. but Japanese release
I've noticed someone posted fixes for HW mode black screen issue, for NTSC and PAL version.
I was wondering if the same could be done for the Japanese release?

EDIT: nevermind, I went and did it myself

Code:
//japanese release

  1. Was wondering if anyone had found a fix for Gadget Racers SLES_519.11;1 (PAL) as the game seems to just lock up entirely when trying to play on Splash Highway (S). Heres a Video of what happens https://youtu.be/wOutlK4jpNU

  2. the game just locks up completely.
