PlayStation 4 cd, will it be able to run it?

Hi! Nice to see yet another PS4 emulator in the works. Just noticed a problem with license though. You've opted for GPLv3 license but have also mentioned

But commercial usage is NOT permitted.

The GPLv3 specifically prohibits adding further restrictions over and above what the license originally states.

See section 10:

You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License.

Also section 7 further stipulates 6 conditions that you may add over and above the license, non-commercial usage not being one of them. So in which case this applies:

If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term.

So people can simply ignore the condition preventing commercial usage and they will still not be in violation of the license. I'd suggest you avoid using a GPL license if you wish to restrict people from using your program commercially.

GPCS4 closes right after startup.

Looking at the debug output of Visual Studio, it loads some DLL files, and after loading C:\Windows\System32\vcruntime140_1.dll, thread 0x5234 ends with code 0.
After loading more DLLs, all other threads end with code 4294967295.
Here's the full output of Visual Studio:

Hello,
we checked GPCS4 with static analyzer PVS-Studio and found some bugs. Here is an article about it. May be you will fix some problems.

For logging: https://github.com/gabime/spdlog
For general formatting: https://github.com/fmtlib/fmt

Also, spdlog uses fmt's syntax (it's bundled).

Basically, the Issues page only accept program bug report.
For feature request, suggestions and other questions, go to Discussions page: https://github.com/Inori/GPCS4/discussions

I suggest do not use path to eboot.bin as cmd line parameters, and use this structure:

GPCS4.exe
app0/
-eboot.bin
-sce_module/
-- libc.prx libSceFios2.prx, and other from game
dev/
-- dce, gc, and other which wants system modules
system/
-- common/
--- lib/
---- *.sprx - from PS4 dump

with this name system, it's easier to just replace app0 folder from game dumps for tests

How about write config for auto compile ?

I think i can try to help
I'm not too many pro in gh actions but i already writed some configs.

P.S. Sorry plz for bad English 😃

just for simple testing on Wine..

This could be useful for testing so I think they should have at least 2/3 significant number for example
40 or 45.6
Is it possible to be done?

Currently Nier runs in an infinite loop, that's correct, but it doesn't call any ScePad functions, which is not expected.

I dont know why but it opens for a frame then closes

When or Will GPCS4 Expand and be able to play other games?

Is this completely different idea or what? Seems yours is developed much faster, can even start one game

Just installed VS22 to try and build this project and was scratching my head at the following errors all day:

Error: linking multiple files is not supported yet. Use -c to compile files individually. GPCS4 glslc 1 (x3)
Error: MSB8066 Custom build for 'Graphics\Sce\Shaders\sce_present_frag.frag;Graphics\Sce\Shaders\sce_present_frag_blit.frag;Graphics\Sce\Shaders\sce_present_vert.vert' exited with code 1. GPCS4 C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\Microsoft.CppCommon.targets 245

The second error is from Visual Studio, not the GitHub project. What I assume is happening is the "Custom Build" for these files, which happen to be all the files in the "Shaders" folder on the GitHub project, is trying to link them somehow. It's failing to link them because that feature is not in whatever version of glslc is being used.

I tried:

• compiling the files manually through the Visual Studio Powershell
• getting rid of the files and then rebuilding
• building the project on VS19

Is there a version of Vulkan that supports linking? Has anybody else had this problem?

1. I do have some compilation issues, some projects(glfw and rtaudio) has outdated Windows SDK - instead of 10.0 (latest installed version) they could have 10.0.17763.0.
2. Should it be like this
   <AdditionalDependencies>Zycored.lib;%(AdditionalDependencies)</AdditionalDependencies>
   at line 71 in 3rdParty/zydis/msvc/zydis/Zydis.vcxproj?

Not Zycore.lib?

I have no more info

I noticed its been about a year since their last commit and was wondering if it's still in development, or just being handled privately, does anyone know?

like this one (Rogue galaxy) : https://store.playstation.com/fr-fr/product/EP9000-CUSA02271_00-SCES545520000001/

I just wanna to have a GUI w/o building the source code.
Probably isn't so simple to implement it.

I'm making gpcs4 great again go to my profile and click on the making gpcs4 running other games for updates!

.pkg files are special, they contain an encrypted (but decryptable, see documentation) PFS file-system.

The PFS filesystem should contain eboot.bin at the root of it.

Unofficial documentation:
https://psdevwiki.com/ps4/Package_Files
https://psdevwiki.com/ps4/PFS

For full PSF implementation some additional steps are needed like getting the title id from an xml file. (Not inside PFS)

<titlepatch titleid="CUSAXXXXX"> <- this is header, but CUSA00001 seems to be a good fallback if unable to read xml.

/mnt/sandbox/pfsmnt/CUSAXXXXX-app0/ <- PFS should be "mounted" there.

For raw eboot.bin usage, just linking it to /mnt/sandbox/pfsmnt/CUSA00001-app0/eboot.bin should be good enough.

Note: The issue is only about running basic homebrews that don't encrypt their assets, not about running full games.

By the looks of it and status on https://emulation.gametechwiki.com/index.php/PlayStation_4_emulators, it DOES look like a ghost repo, unfortunately.
I want to contribute, but am not willing to take hold of this on my own...

The emulator will crash randomly on somewhere near malloc, about 1 or 2 times over 10 times launch.

Orbital roadmap mentions they have a
GCN-to-SPIRV translator.
Cf https://github.com/AlexAltea/orbital/wiki/Roadmap
Since this is hard to get right, maybe you could join forces/code on this specific task?

Help?

I am not an expert but like many i would have expected the PS4 to be easier to emulate than the PS3 since its hardware is much closer to PC.
As for the CPU you can just use the host x86 cpu through a hypervisor e.g haxm which is what orbital is doing. Or by using e.g. Box64

The remaining complexities would be:
Low level differences vs a regular pc architecture
And notably, a GPU API mismatch (the PS4 expect raw GCN assembly??)
However I think it would be a mistake to not seriously ask yourself whether the PS5 would be actually easier to emulate.
It's still x86 and an updated GCN but it might have less lower level differences vs a regular pc architecture and might have less of a GPU api mismatch.

But my neophyte opinion would be that the Xbox series X/S would be the easiest platform to emulate.
Since it's still a x86, updated GCN BUT If I recall correctly, xbox serie X games are coded in direct X 12, which is much easier to map to vulkan and crucially is natively supported on windows. The OSes would also match.

Unrelated, if the GCN to spirv mapping is a ley difficulty, couldn't you offload GCN assembly directly to the host GPU if the host GPU is an AMD gpu?
The switch emulator Yuzu supports this for Nvidia gpus.

BTW I really think you should do a patreon, even if it's just currently a part time project, it could become big!

subj

As state by the comments:

There may be some bugs for current implementation
(or bugs for validation layer, I'm not sure),
It can not print more than one debug string,
and even worse, the validation layer always complains 
buffer size not enough even I provide 65536 bytes.
And crashes randomly.
I've compared the spir-v code generated by
this function and glslc compiler, and I see
no difference, so I don't know why by now.

An ideal state would be the game runs in an infinite loop processing input messages, just without graphics output.
This crash possibly due to unimplemented import functions.
Especially sceKernelVirtualQuery, I don't know what it will return on a real PS4 machine.
Maybe a better way is to hook this function on a real PS4 machine and log its' output.

for me, as every ps4 game includes own version of libc, better way to load provided version of libc.prx

Tried with we_are_doomed branch (testers already boots that game so I tried too, some commits before - because of logging to text file) - gpcs4 just closing, only thing i have got - white screen for second.
Latest logged thing is:

Could it be due old (if it possible at all) TLSManagerWin - I'm using Windows 10 17633.979?
I attached log file but its shrinked for some reason, have to get by DebugView
Hardware - Intel i3-6100, RTX 2060.

Currently basic-sample demo will crash on some functions.
If we can run it in an infinite loop without crash, just lacking of graphics output, that would be good for future module development.

Is this still actively being worked on? From what I've seen there hasn't been a pull since April and it says it was last updated in 2019 so I guess I'm curious, Also if there's a Discord where fans or random people can just join and look in to view progress from time to time I'd love to have a link (I don't know if there's a way to flair this a certain way so apologies in advance)
