No DT_SCE_ORIGINAL_FILENAME

Initialize failed: cannot open /mnt/sandbox/ITEM00001_000/app0/eboot.bin -> cannot parse file info -> no DT_SCE_ORIGINAL_FILENAME.

Occurs on the Itemzflow Game Manager: https://pkg-zone.com/details/ITEM00001

I doubt if it actually boots on the actual PS4. Can you test it?

[VocalFan]

Uh, sir, I use Itemzflow to dump my games from my PS4... It's one of the most popular apps for homebrew.

[VocalFan]

__int64 __fastcall obj_get_original_filename(__int64 a1)
{
  __int64 v1; // rax
  __int64 result; // rax
  v1 = *(_QWORD *)(a1 + 392);
  if ( v1 )
    result = *(_QWORD *)(v1 + 216);
  else
    result = 0LL;
  return result;
}

The above function is unrelated to this error.

[VocalFan]

Good thing is that since it's homebrew, it's easy for you to test as you can download it

The problem here is why it is working on the actual console. If no DT_SCE_ORIGINAL_FILENAME the acquire_per_file_info_obj will fail and it will cause exec_self_imgact to fail too.

Idk, but you could see my video on 348 of it working, as I used Itemzflow to access the pkg installer and open the controller test.

Idk if this helps, but here's a KLog from my PS4 of me launching the app:

Not much useful information in the log. Do you know how to get the kernel log?

[VocalFan]

As far as I can tell, Klog is the best I can get.

[red-prig]

As far as I understand from the reverse, the SCE_ORIGINAL_FILENAME and SCE_MODULE_INFO fields are required only in cases where: SCE_HASHSZ and SCE_SYMTABSZ are present as well as hdr_e_type=ET_SCE_DYNAMIC

Thanks for the information. I suspect this one is not a dynamic executable because from what I remembered the kernel will be called acquire_per_fileinfo only when it is dynamic executable.
