Decompile Game_16 (#167)

* Game_16 OK

* Remove unnecessary FadeControl constructor definition

* Define HW_RESET_PARAMETER_BUF macro to replace hardcoded address

* Refactor Game constructor to use proper C++ initialization

Address Yanis' review comments:
- Make Game::func_0202cf44 static with Game* parameter to allow
  passing as callback pointer
- Replace raw mUnk_00c array with Game_0c class containing constructor
- Add Game_0c constructor with inline initialization calling func_ov016_0211fab8
- Add FadeControl_Derived1 class for mFadeControl member
- Use C++ initializer list in Game constructor for mModeId, mPrevModeId,
  mMode, mUnk_00c, and mFadeControl

* Fix Game constructor and FadeControl initialization

- Use PAD macro in Game_0c instead of unk8 pad[]
- Pass 'this' instead of 'pad' to func_ov016_0211fab8
- Add FadeControl constructor that calls _ZN11FadeControlC2Ev
- FadeControl_Derived1 now uses empty constructor (base class ctor called automatically)
- Update mUnk_00c.pad to mUnk_00c.pad_0x00 (PAD macro creates named member)
- Add types.h include to nds/system.h

* Remove explicit call to mangled constructor symbol

- Removed _ZN11FadeControlC2Ev call from FadeControl constructor
- FadeControl now has an empty constructor (called automatically by derived classes)
- FadeControl_Derived1 uses empty constructor which calls base class ctor

* Update symbols.txt for func_0202cf44 signature change

Changed mangled name from _ZN4Game13func_0202cf44Ev to
_ZN4Game13func_0202cf44EPS_ to reflect the function becoming
static with a Game* parameter.
