Editing Official Configuration Files

Here are configuration files extracted from official packages to improve PS2 emulator compatibility on PS4. Most of them also require emulator/recompiler files from extracted pkg to work correctly.

-- The game expects PATH3 happens before VU1 xgkick, but actually Olympus doesn't do like that.
--	Game kicks  : PATH3(Context1) PATH1(Rendering using Context1&2) PATH3(Context2)
--	Game expects: PATH3(Context1) PATH3(Context2) PATH1(Rendering using Context1&2)
-- Hence VIF1 DMA needs to be delayed.

-- All JAK titles have a silly way of obtaining the PS2 Timestamp Counter. A binary code snippet is written
-- into a NON-CONST array, like so:  static u32 getTSC[] = { 0x40024800, 0x03E00008 }; and then that snippet is
-- called via:  ((u32 (*)())getTSC)()
--
-- Actual disasm of snippet:
--    129780:40024800     mfc0         $v0,$count
--    129784:03E00008     jr           $ra
--
-- Because the code is right next to data in the .data section of the process, the emulator's page fault protection
-- gets tripped up constantly and the code must be re-validated on every invocation.  Interesting aside: had the devs
-- marked the array as 'const' and thus had it placed in .ro_data, there wouldn't be a perf issue in the emu since
-- page invalidations only occur on writes.
--
-- Solution: rewrite the code which calls this function to simply execute mfc0 inline instead.  Typical pattern which
-- invokes the PS2 TSC read:
--    108c80:8c629790 	lw	v0,-26736(v1)

-- z=0x321 won't be available on the packet (interpolation differences between
-- the real PS2 and our gs)
-- it gives some values (50.0f) to get +1 on Z value for the highlighted object.
