* First crack at refactoring NDS and DSi into objects - Remove all global/`static` variables in `NDS` and related classes - Rely more on virtual dispatch when we need to pick methods at runtime - Pass `NDS&` or `DSi&` to its constituent components where necessary - Introduce some headers or move some definitions to break `#include` cycles * Refactor the frontend to accommodate the core's changes * Move up `SchedList`'s declaration - Move it to before the components are initialized so the `map`s inside are initialized - Fields in C++ are initialized in the order they're declared * Fix a crash when allocating memory * Fix JIT-free builds * Fix GDB-free builds * Fix Linux builds - Explicitly qualify some member types in NDS, since they share the same name as their classes * Remove an unnecessary template argument - This was causing the build to fail on macOS * Fix ARM and Android builds * Rename `Constants.h` to `MemConstants.h` * Add `NDS::IsRunning()` * Use an `#include` guard instead of `#pragma once`
