.: Introduction :.
  This unQue patch series is directed at restoring save support and reversing library changes in iQue titles so they function reliably on retail consoles and a wider range of emulators--at the expense of breaking iQue support.
  For the sake of emulators/flashcarts that look at GUID codes to differentiate these patches from retail titles, a GUID and timestamp were added.  The device type is set to "B" for "BB Player" (not "Q"), and region to "C" for China or "W" for Taiwan/Hong Kong.  Internal names are encoded using codepage 936 (normally CP 932).  This information is not used by console.  Bootstraps (IPL3) are swapped to match their retail counterparts; iQue does not, in fact, run this code, and many use the "development" IPL tied to a CIC.

  "Zelda Chuanshou Shiguang Zhi Di", "Legend of Zelda: Ocarina of Time" or "Zelda no Densetsu: Toki no Ocarina" in other regions, uses emulated SRAM on iQue.  Data is loaded into the top of RDRAM and flushed back later.  All controller slot devices are emulated as simple reads and writes to an assigned address range.  Functions to check if a Rumble Pak is present and send it values are stubbed.  The BB Hack flags allowed mirroring the main controller to a port of your choice.
  
  The patched ROM expects a 256k SRAM on its board; CIC is 6105.  Rumble Paks are supported.
  The displayed cost of light arrows in the Simplified Chinese version has been corrected from 2MP to 4MP.
  
  An 8MB Expansion Pak is REQUIRED for the Traditional Chinese version.  See "Notes" below for more information.
  An Expansion Pak is optional but VERY HIGHLY RECOMMENDED for Simplified Chinese.  Without one the game is subject to the same load failures and crash bugs the original iQue release is plagued with.


.: Patching :.
  Apply the xdelta patch using the similarly named xdelta; use version 3.0.8 or up.  The patch will only apply to a *decrypted* ROM in native (big-endian) byteorder.
  (The process for extracting your console's tickets and decrypting an extracted ROM are well outside the scope of this readme.)
  There are two versions of this title.  Use the appropriate patch as described below.

.: Notes :.
*) Not all changes to the standard library are reversed, only those which directly affect operation or expose iQue-specific registers to emulators (console won't be affected, but emus may throw errors).  This includes rewriting system initialization, controller pak detection, preNMI, and most dedicated save-related functions to some degree.  Other code is already isolated when iQue hardware is not detected.
*) Heap sizes, due to a number of factors, are smaller in iQue versions--too small to allocate space for all the data that needs to be loaded at any given time.  The Simplified version predictably runs out when dynamic objects are in use, horseback archery a notable offender.  This caused unpredictable behaviour and crash bugs.  Side quests like poe hunting are difficult or impossible to complete.
   iQue developers used a dirty hack in the Traditional Chinese version to circumvent this problem.  They dedicated 1MB of rdram over the normal* rdram size of 4MB, split into 16 parts, and manage this manually.  File object 0x14 (ovl_En_Horse) will always load here, and any files that fail to load onto the heap will attempt to allocate another block in this area.  As a result, Traditional REQUIRES an 8MB Expansion Pak.
   The patch for Simplified uses a different, more practical solution.  64DD features were designed to use 6MB of rdram (not 8MB, funny story), and although 64DD code is not present the memory manager still accepts an argument to use the additional memory when provided.  By passing TRUE instead of FALSE, the extra 2MB will be added to the heap when present, happily solving the problem with room to spare.
   If you wish to experience the bugs in the original release (arguably speeding up the game a smidge), remove your Memory Expansion Pak.
*) The "no controller" warning remains in English.
*) All 64DD detection and its file substitution mechanism--the entire n64dd code blob in fact--were removed.
