* Sprinkle `const` around where appropriate
- This will make it easier to use `NDS` objects in `const` contexts (e.g. `const` parameters or methods)
* Remove the `const` qualifier on `DSi_DSP::DSPRead16`
- MMIO reads can be non-pure, so this may not be `const` in the future
* 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`
* Reorganize namespaces
- Most types are now moved into the `melonDS` namespace
- Only good chance to do this for a while, since a big refactor is next
* Fix the build
The DS battery level is configured via the SPI Power Management Device,
and the DSi's is configured via the I2C BPTWL. Add support for changing
these registers and add the "Power Management" dialog in the UI.
also including:
* getting rid of shitty strings
* all new, cleaner ROM handling code
* base for DSi savestates
* GBA slot addons (for now, memory cart)
