Proceeding the GhidraOrbis PS4 Loader Plugin, his GT7Tool to Decrypt / Unpack GT7 PS4 Archives and the recent PS5 Hacking Progress including 4.03 PS5 Error Codes and PS5 4.03 Registry Key Entries / PS5 Title IDs today PlayStation 5 Scene developer @flatz released via Twitter a PS5 ELF Loader Plugin for use with the Interactive Disassembler IDA Pro 7.5 alongside PS5 Symbols (PS4 Symbols / Debug Symbols MEGA Archive) on his Github repository. 
Download: ida_ps5_elf_plugin-main.zip (includes gcc_extab.py, prospero.til, ps5_elf.py and ps5_symbols.txt) / GIT / PS5 BD-JB ELF Loader / sce_symbols via SiSTR0 forked from sce_symbols via zecoxao
Here's further details from the ida_ps5_elf_plugin's README.md: IDA PS5 .elf plugin (c) 2021-2022 by flatz
Instructions
If you use some cracked version of IDA and see annoying __usercall calling conventions that breaks code analysis when decompiling x64 functions, then it can be fixed by appending idapro to DISABLE_USERCALL list at cfg/hexrays.cfg.
Another solution is modifying artificially broken hexx64.dll plugin by changing idapro string written there to hexx64, e.g.:
Known bugs
Update: In other PlayStation 5 Symbol news, below is a simple Windows symbol program visible only on PS5 as it was previously patched on PlayStation 4. 
Pro-tip for debugging some of IDA's plugins:
P.S. Should work for "Remote XNU debugger", for example.
this means no more symbols for anyone. probably happens the same on ps5 8.00 and beyond too
as a late xmas gift, the epic games bundle for 4th January until 11th January, Marvel's Guardians of the Galaxy ships with the game's PDB containing full debugging symbols!

Instructions
- Put all files into their corresponding directories by keeping this directory's structure.
- Use 64-bit IDA and standard ELF64 for x86-64 (Unknown) [elf64.dll] when loading .elf/.prx file.
- Apply any kernel options that you use usually.
- If you see warning Unsupported or unknown image type, then press Yes, thus ignoring it.
- Wait till plugin complete its own work. I use many heuristics to locate a lot of useful information within .elf file, so please be patient.
- Ignore all possible warnings that may happen during processing. Some of structures are getting updates from one version of *** to another, that may cause warnings as well until they will be fully supported.
- If you want to add new symbols or edit existing ones, then update file cfg/ps5_symbols.txt and til/prospero.til optionally.

Code:
69 64 61 70 72 6F 00 00 72 73 70 00 72 62 70 00 -> 68 65 78 78 36 34 00 00 72 73 70 00 72 62 70 00- Need to update some structures, e.g. sceProcessParam, to reflect more fields that it may take.
- Need to parse exception handler sections properly because their format was changed since PS4. Could be useful to tweak function boundaries even more.

Code:
activate debug mode using `idaapi.inf_set_cmtflg(idaapi.SCF_TESTMODE)` and you may see verbose logs.- Debugging Games - Symbols, Symbols Everywhere! Massive Copy of Games With Symbols.
