Editing Official Configuration Files

These are configuration files extracted from official PS2 game packages. Most of them require emulator/recompiler files from their extracted pkgs to function optimally.

-- This game seems to have a problem (sensitive) with frame count on the script engine.
-- On our emulator, frame counting is slightly different from the original.
-- therefore it reads out 'overun' script command, which is 'cmd_fade' to fade-in.
-- At here, we will skip FADE-IN command if the situation meets the requirement.

-- Because the code is right next to data in the .data section of the process, the emulator's page fault protection

-- 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

Notes:

The intro sequence (SNK logo, movie) only plays ONCE, on startup, never again, no matter how long you leave things in attract mode
this works to our advantage.  For this reason it's probably easiest to have the current scanlines / bezel options kick in immediately
after the SNK logo.


FEATURE SCRIPT : Rom Base is is set to 0 as soon as you select 'return to main menu' although any music that is playing at the time
continues to play until you confirm the 'save to memory card' choice, this might not work to our advantage.

Rom base is set to 00020000 then the actual value as soon as you select a game from the main menu.

text base and RAM base get set as soon as the actual emulation starts for each game.

-- z=0x321 won't be available on the packet (interpolation differences between
-- the real PS2 and our gs)

-- fix for a node corruption.
-- here's what happens (from Ernesto)
--
-- Well, I was finally able to track down the issue. It's actually difficult to explain and the actual trigger is still unknown to me, as it seems to be timing related somehow.
-- But, I found a way to reliably detect it and work around it. Basically, when the bug happens, CSGNode::AddChild will try to add a child node that's already a children of a different root node.
-- That causes all sorts of havok and it's what ends up causing the node child list to eventually be deallocated and the render to crash.
