Generic host, gfx and tools taken from d2r-mobile (MIT), with the D2R gameplay, diagnostics and Blizzard/Granny/movie layers removed. - hle_hid.c: generic standard-controller layer (all Npad styles) - hle_sdk16.c: newer-SDK oe/time/pl/vsync/diag hooks - hle_offline.c: offline stubs for prepo/ldn/socket/ssl/nifm/nsd/friends/ngc/err - hle_fs.c, hle_account.c: SDK 16 overloads - loader.c: unreferenced forced hooks only logged (DM_FORCE_STRICT=1 aborts) - NVN: API 55.15, 13 newer names, ~45 state-only functions, tex_t packed to 0x80 (Mario allocates NVNtexture as 0x80; 0x88 corrupted the heap) Frontier: null read at main+0x64763c inside the frame loop.

// 按偏移读写原版界面控件的「类专有字段」之前，先核它是不是预期的那个类（虚表）。
|
||
// 来由：按名字找到的控件不保证是当初量偏移时的那个类（布局改了、同名控件换了类、原版把槽位换成别的控件），按偏移写下去就是往别的对象里乱写。
|
||
// 所有控件共有的基类字段（名字 +8、可见 +0x50 / +0x51、子控件 +0x58 / +0x60、矩形 +0x70）不用核。
|
||
// 虚表值是 main 模块内偏移（3.3.94012），宿主实读：
|
||
// Before reading or writing "class-specific fields" of a native UI widget by offset, check that it is the expected class (vtable).
|
||
// Why: a widget found by name is not guaranteed to be the class the offsets were measured on (layout changed, a same-named widget changed class, the game swapped the slot for another widget), and writing by offset then scribbles into some other object.
|
||
// Base-class fields shared by all widgets (name +8, visible +0x50 / +0x51, children +0x58 / +0x60, rect +0x70) need no check.
|
||
// Vtable values are offsets within the main module (3.3.94012), read on the host:
