What is shown

The home screen, the file browser, the picture viewer and System information all render and respond to the controller. Three readings are wrong:

• System information > Network. State is connected and Link is wired. Address, Subnet mask, Gateway, Primary name server and Hardware address all show -, and Largest packet shows 0 bytes.
  • The app reads these values with sceNetCtlGetInfo (through SharpProspero's NetworkInfo).
  • On main that call returns NOT_CONNECTED for every code, while sceNetCtlGetState reports IPOBTAINED.
• System information > Console. It shows Time zone UTC+00:00 and Summer time no on a host in Central European Summer Time. sceSystemServiceParamGetInt answers 0 for both, while libSceRtc and libc use the host's zone.
• Opening a JPEG from the file browser. I used /data/anyps5-test.jpg, a 640x360 baseline JPEG; the viewer shows "Nothing is open.".
  • SharpProspero's JpegImage.Decode uses libSceJpegDec's own structure layouts: create parameter 0xC bytes, decode parameter 0x30, image info 0x24.
  • AnyPS5's libSceJpegDec uses libScePngDec's layouts instead. So sceJpegDecParseHeader never writes the output size the app reads at 0x1C/0x20, and the decode stops there.
  • sceJpegDecCreate would also reject the app's 12-byte create parameter.

Current blocker

No stop. The wrong results are fixed by these open pull requests:

• fix(libSceNetCtl): answer sceNetCtlGetInfo from the host IPv4 interface #5056 (sceNetCtlGetInfo). With it, the Network tab shows the host's address, netmask, gateway and name server, the hardware address sceNetGetMacAddress reports (02:50:53:35:00:01), and 1500 bytes.
• fix(libSceJpegDec): use the JpegDec parameter and image info layouts #5072 (libSceJpegDec structure layouts). With it, the picture opens and displays correctly.
• fix(libSceSystemService): report the host time zone and summer time #5084 (time zone and summer time). With it, the Console tab shows UTC+01:00 and yes on that host.

How it was run

• The catalog eboot.bin was unwrapped and relinked (--windows), and run from a folder with app0 and a data folder that holds the test JPEG.
• The screens were reached with APS5_PAD_INPUT_FILE and tools/pad_input.py:
  • Console tab: from the home screen, down 7 times and cross.
  • Network tab: the same, then right 2 times.
  • JPEG: from the home screen, down 2 times and cross for Data /data, then down 2 times and cross on the JPEG.
• The screens were captured with APS5_DUMP_FRAMES.
