So with my code whole screen is still flickering?
Edit: And does your codes eliminate flickering?

Correct, your code still has the major flickering and graphical errors. I can't see a difference on netemu.

My code stops all of the flickering, but in turn doesn't render of a lot of geometry (characters and some environment), so a lot is missing.
 
Buffy the Vampire Slayer: Chaos Bleeds (SLUS-20566) (experimental code)
Code: 
3D 00 00 00 11 11 00 00 0A 00 00 00 01 00 00 00
E8 18 20 00 10 06 08 0C 00 00 00 00 00 00 00 00
This fixes the flickering screen and graphics, but the ground and walls are missing most of their textures...this is really only for testing purposes as a real fix needs to come out of this, but its some progress at least.

EDIT: Actually doesn't fully fix the flickering...but it is heavily dependent on/related to this function

thanks for help. the pal version is lot worse it seems. the options menu at start screen isn't completely drawn, even with your ported config @mrjaredbeta, but at least the player character is visible now. still flickering textures but not as bad as before

yours, @kozarovv, has no effect

I remember about pcsx2, they mentioned sth about switching videomode 50/60hz. in earlier version, I think it was 0.98, it could be fixed with speed hack option or was it the internal fix? dunno exactly anymore

That game seems to do something with strict timing. When vif is too fast before it stall, then data is overwritten.
This is very problematic on netemu since VIF is instant here afaik. Dunno why (and what is more important where) game do this. Because it looks like it expect to VIF stall occur at some point to break data transfer. This just can't happen on netemu since VIF here first finish transfer, then do stall. I will look more into that, maybe we can force break or something.

Also game seems to do weird crap here. Probably read of those registers should trigger some interrupt, otherwise i don't know why read them as literally none of values are ever used.

Notice it just read, but never use value for anything.

ported partially working config by @mrjaredbeta
SLES_518.90
Code: 
3D 00 00 00 11 11 00 00 0A 00 00 00 01 00 00 00 88 23 20 00 B8 08 08 0C 00 00 00 00 00 00 00 00

@kozarovv
do you still remember the patch, to only make replace pattern necessary? I cannot find your thread anymore. I am also using 4.82 or 4.84 netemu on 4.21
 
The wiki says that Project Zero is unplayable because "Game freezes in the first chapter after cutscene". That isn't true, I'm about to finish the game, in some cutscenes it looks like a freeze but if you press start and wait a few seconds the game continues without problems

it's official ps2 classic game.
 
Here is config that should make Buffy (US) much better, maybe even hardly, but playable.

Code: 
3d 00 00 00 11 11 00 00 0a 00 00 00 02 00 00 00
1c b5 26 00 51 00 c0 10 51 00 00 10 f0 0c 26 00
00 00 04 8e 00 00 00 ae 00 00 00 00

Like i said earlier issue is VIF that seems to have terrible timing on netemu.
Faster EE, or slower VIF1 should fix it. But we don't have those kind of options..
Only second part of config were tested, and it is successfully eliminating flickering.
First patch should make visible things that earlier disappeared (floor, etc.), but still corrupted.

Edit: mrjaredbeta tested this, and it seems that on ps3 only second part of config work. So it will only eliminate flashing for now..

Shadow Hearts (SLUS-20347) (SLPS-25041)
Code: 
3D 00 00 00 34 12 00 00 0E 00 00 00 3C C6 21 00
21 00 00 00 00 00 00 00 00 00 00 00
Fix all FMV slowdown/desync (coupled with lottery fix from a few months back). Only tested on SLUS-20347 but it should work fine for both regions.

Safe to say command 0x21 will fix FMV slowdown and stuttering problems in many games, and it's used officially in a few official PS2 Classics (like Fatal Frame 2).

Can you upload your memory card image (.VM2) with your save on it? It might be fixable with an accuracy command. I could take a look at it.

Thank you for your hard work. Hoping the issues with the sequels get fixed.

EDIT: Btw, idk if it's my place to ask, but I wonder if the puzzle glitch in soul reaver 2 can be fixed.

While it's on my mind, a while ago I was playing Xenosaga I and during a cutscene after the gargoyle boss, the game softlocked around 5:05 on this cutscene:
. Also in one of the cutscenes while Shion is on the ship, while there's a grayscale dream, the screen is black (not a crash).
" I wonder if it's possible to fix.

Hey dude! I'm actually having the exact same problem with the exact same cutscenes.
I've been digging around a bit and I've heard that very similar glitches occur on PC emulators and that it may be due to the dual layer aspect of the DVD CD.
You are using a slim/ps2_netemu right? Have you found anything regarding this issue? There's supposedly a single layer undub multi-disc version out there, tried that?
We might just have the same faulty ISO though, haha... I haven't tried just skipping the cutscene though, cuz of how long the gargoyle fight is.
