Rpcs3: [BLES02237] Unimplemented syscall 462

[xiangzhai]

Hi rpcs3 developers,

rpcs3 435ea8d55379a887442916ff309c6f1e28fc9652 is pretty cool about binary translation through LLVM! but unimplemented syscall 462:

U {PPU[0x1000000] Thread (main_thread) [0x028c10e4]} HLE TODO: Unimplemented syscall syscall_462 -> CELL_OK
U {PPU[0x1000000] Thread (main_thread) [0x028d0e64]} sys_prx TODO: _sys_prx_register_module()
U {PPU[0x1000000] Thread (main_thread) [0x028d10bc]} sys_prx TODO: _sys_prx_register_library(library=*0x28d36a0)

F {PPU[0x1000000] Thread (main_thread) [0x028c792c]} St13runtime_error thrown: Unregistered PPU function

So I checked the COMPATIBILITY for BLES02237, then I realized :)

But how to fix? The patch is not related to this bug.
I want to dig into rpcs3, please teaching me, thanks a lot!

Syscall 462 does not exist on retail consoles, so it being unimplemented would not affect game emulation. The game is broken by something else. That specific error in your log is because of using the PPU LLVM decoder. Using PPU Fast interpreter would possibly make it go further. But as seen on the compatibility list, it was recently tested and did not work.

@isJuhn thanks for your kind response! BLES02237 compatibility is just like Magic to me :) it is easy to fix GCC compatible toolchain issue :) but I think it is not easy to fix game compatibility, I want to dig into it, please teaching me, thanks!
