Backbreaker Vengeance [NPEB00592]

Game is stable now, but the field/crowd is black. Previously 'Write Color Buffers" helped with that (made a weird yellow/green though) but now that being active causes a crash before main menu (Vulkan):
E {PPU[0x1000001] Thread (File System Thread) [0x01466090]} 'sys_fs_open' failed with 0x80010006 : CELL_ENOENT, “/dev_hdd0/game/NPEB00592/USRDIR/media/cameras/test.dat” [1]

Update:
After hours of testing, I’ve found a (good) working config on RPCS3 v0.0.4-6271-8a3759f4 Alpha | HEAD

• OpenGL
  
• Color Buffers
  
• Force CPU blit emulation
  

 
With this game gfx are nearly perfect (see screenshot), minus a glowing effect on point patches and black boxes around people in stands (both very minor). Full fps, minus a few stages with a lot of activity, where it gets a tad slow. The game also does freeze sometimes but I can play quite a bit before that happens.
 
Vulcan Regression Info:
Unfortunately, the game cannot be played (with proper gfx) with Vulcan right now, which i think would address the speed concerns noted above.
Last build with Vulcan + Color buffers working was 22 days ago. Since then, there were two kd-11 check-ins that made the game worse each time. Details below with logs attached:
 
First regression:
https://ci.appveyor.com/project/rpcs3/rpcs3/build/0.0.4-7112/artifacts (kd-11)
A lot of text is broken and freezes while loading gameplay. Need task manager to kill instance when this happens (bad).
Error:
E {rsx::thread} RSX: Could not gather all required surfaces for cubemap generation
 
Second regression (current behavior):
https://ci.appveyor.com/project/rpcs3/rpcs3/build/0.0.4-7251/artifacts (kd-11)
Now it freezes before main menu with this error:
E {PPU[0x1000001] Thread (File System Thread) [0x0143c090]} 'sys_fs_open' failed with 0x80010006 : CELL_ENOENT, “/dev_hdd0/game/NPEB00592/USRDIR/media/cameras/test.dat” [1]
 
Note almost ALL the above info is the same for the original Backbreaker disc game.
