PS4 [Research]PS2 emulator configuration on PS4

[Stayhye]

What is really strange about the Jak * emus. Scarface boots into a blackscreen unless you add "eeObj.SchedulerDelayEvent("vif1.dma", 0x6500)" to the lua script. At least for me. This can even say "vif1.dma", 0x0000 and it boots up just fine. It seems that this command with the different event options could be interesting.

Nice find!! I am Testing new commands with Scarface now.

got the budokai 3 patch to work on jak3 emu still have to press start yo skip but at full speed in game

Updated fix for Urban Chaos Riot Response. Much, much better framerate by porting @mrjaredbeta fixes from ps3

https://www.psx-place.com/threads/r...nfiguration-on-ps4.16131/page-123#post-319739

Was tested! In end video u can see bug with blue flame from a pipe (its invisible) noticed, but you can pass it! Apart this small bug all is fine and framerate is much better now!

 

[Stayhye]

emu accepts these:

eeObj.WriteMem32(0x00643790,0x03e00080 * X) -- X can be any integer

or 

eeObj.WriteMem32(0x00643790,0x03e00080 + X) -- X can be any integer

What could this be doing in code?

Don't worry, its not an emulation bug. Those codes disable some effects and that is a side effect of it.

ok, good to know, thanks for info!

 

[Vika23]

Also @mrjaredbeta maybe you able port your own config of The Suffering to ps4 and probably we can defeat that bug also on ps4?

 

[mrjaredbeta]

@Vika23 Not unless there is some PS4 command that is equivalent to the 0x04 command on netemu. I believe you or someone else tested lopnor with this config and it did nothing, so probably this command is not compatible with PS4.

yes i was test lopnor method, sadly bug stay still

 

[SeanRanklin]

@Vika23 or anyone else: do you mind testing Tenchu: Wrath of Heaven on PS4? I'm curious if the freeze is similar to PS3. Compat list states it freezes before game begins and PAL version crashes after story mode.

Thanks!

I will test, u have a config?

I am wondering if anyone has any update for this game yet

Still same, alot Graphical bugs and also will random crash

what is 0x04 command on net emu? what does it do?

 

[Vika23]

what is 0x04 command on net emu? what does it do?

looks like Increasing the parameter seems to clear up all possible graphical glitches (it was note for ps3 config)

Works finally! some FMVs are very slow. Gameplay is fine so far. Anyway It makes it to gameplay finally!

The crash is the problem, the graphical glitch I don't mind. It's such an awesome game.

One of the most complex PS4 custom configs I've seen so far! I really appreciate your time and patience figuring out the different emu options. Can you explain why you implemented the "local code_check" like that? What is "SchedulerDelayEvent" (sif1.dma) used for in lua?

they are all un-commented.

http://tylerneylon.com/a/learn-lua/

"local code_check" is used to convert e codes from PCSX2 to LUA. If enabled, they will remove the black bars from cut scenes. Although some will turn red. To enable, remove --[[ and --]] from config at beginning and end of said code

@kozarovv explained here https://www.psx-place.com/threads/r...onfiguration-on-ps4.16131/page-89#post-295590

What is "SchedulerDelayEvent" (sif1.dma) used for in lua?

nothing at all. Left over debris from testing.

which difference in Subsistence and Snake Eater? I boot Snake Eater with eternal ring v2 and gameplay looks like Subsistence! Im not fan of MGS series! Did second config with star ocean match with Snake Eater too ot it just for Subsistence?

CLI will, not LUA. Main reason for me to choose Subsistence is the free camera control. Snake Eater had MGS1 / MGS2 camera scheme
