After two hours of in-depth testing, you have fixed the graphics issues of this game. Thank you very much. Does this mean that other King of Fighters games will also be fixed?

Well, if issue is the same. I can look into it.

All graphics issues have been fixed
--gs-use-clut-merge = 1
--gs-kernel-cl = "clutmerge"
--gs-kernel-cl-up = "clutmerge2x2"
Can fix HP slot flicker
--force-frame-blend=1
--gs-use-deferred-l2h=0
Can repair the background graphic flower screen

SLPS_255.25 graphics problem fix
SLPS_256.60 may be different due to graphics problems, the configuration does not work, there are no graphics problems in the game, only after the start menu and START button

Like you can see, even with the same engine, and potentially same issue, with exactly the same function. There is still a lot of lottery that fix gonna work, or not. Anyway. We have now 2 new games fixed, 1 official fixed by custom config and additionally one region ported. Not bad ratio with almost no effort
Thanks for testing, and HP fix
Edit: Can be worth to try that any other SNK Playmore games have similar issues, game engine can be the same. But that is task for longer time

I started reversing Tony Hawk engine, and found few noticeable issues on VU. First thing, game use evil branches. So branch inside branch delay slot on VU.
Second, game land many times on D bit, that should halt execution only on debug machines, is not clear how ps4 emu handle it yet.
Finally bad rounding, but that shouldn't be issue when booting game. So let's leave it for now.
So here is test config for Tony Hawk games (part 4 or higher):
First attempt:
Edit: Here is full attempt (with fixed rounding too) for SLES_547.14

Code:
[32c8] (000002ff) NOP
[32c8] (520a07fd) IBNE vi10, vi00 [32b8]
[32d0 - delay slot] (000002ff) NOP
[32d0 - delay slot] (42020027) BAL vi02 [3410]Second, game land many times on D bit, that should halt execution only on debug machines, is not clear how ps4 emu handle it yet.
Code:
microVU1: D-bit set! PC = b70
microVU1: D-bit set! PC = bb0
microVU1: D-bit set! PC = b70
microVU1: D-bit set! PC = bb0
microVU1: D-bit set! PC = b70
microVU1: D-bit set! PC = bb0
microVU1: D-bit set! PC = b70
microVU1: D-bit set! PC = bb0Finally bad rounding, but that shouldn't be issue when booting game. So let's leave it for now.
So here is test config for Tony Hawk games (part 4 or higher):

Without this configuration, the game freezes on the reading progress screen.
It seems that the configuration has no effect
I created two PKGs, one with no configuration and one with the above configuration, all with the same problem.

There is no music on the loading screen, and the transitional CG music is normal. Still the same problem, freeze!

The test passed and the audio problem was still a flaw.

We can try to mess with audio if you want. But i have only that idea.

I need tester with SLUS_205.50 True Crime LA. I see config on wiki, but it include patch to iso. I want to try do that in lua.
Test is fast. It will hang on title screen, or goes ingame if config work.
Edit: if that's not gonna work, then i want to try emuMediaPatch
Edit2: This one gonna work for sure, but is harder to port, will be nice if first one work..
Code:
apiRequest(0.1)
