Fix a crash when using DSi mode in debug builds on macOS (#1976)
Store the BIOS images in `NDSArgs`/`DSiArgs` through pointers, not directly

- This will make it easier to keep such objects on the stack

Sprinkle `const` around where appropriate (#1909)
* 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

Remove the last `ConfigEntry` state (#1902)
* Get rid of `ConfigEntry::ExternalBIOSEnable`

- Now the BIOS files themselves are checked
- The frontend's `Config::ExternalBIOSEnable` is not affected

* Add `JITArgs`

* Pass the JIT status to the `ARM` constructors

* Encapsulate `NDS::EnableJIT`

* Pass `JITArgs` to `ARMJIT`'s constructor

* Remove the `JIT_*` `ConfigEntry`s in favor of members

- Allow all the JIT args to be set with `NDS::SetJITArgs`
- Encapsulate the JIT-related parameters in `ARMJIT` so they can reset the block cache if changed
- Update the active (or newly-created) console in the frontend with adjusted JIT args

* Make audio bit depth and interpolation configurable in `NDSArgs`

- Define enums for both
- Give those settings default values in `NDSArgs`
- Remove `ConfigEntry::AudioBitDepth`
- Initialize these settings in the relevant SPU constructors

* Move the last DSi-specific logic in `Reset` to its own subclass

* Remove `ConfigEntry::DSi_FullBIOSBoot`

- Add members to `DSi` instead for getting and setting this
- Update the frontend to accommodate these changes

* Oops, missed a spot

* Remove `ConfigEntry::Firm_MAC` and `Platform::GetConfigArray`

- Also move the MAC parsing code to `ROMManager`

* Remove the last `ConfigEntry` state

- Make GDB support configurable via members

* Add some `#ifdef`s that I'd almost forgotten

Refactor how save data (including SD cards) is initialized (#1898)
* Remove `FATStorage::Open` and `FATStorage::Close`

- That's what the constructor and destructor are for, respectively

* Add `FATStorage::IsReadOnly`

* Slight cleanup of `FATStorage`

- Make it move-constructible and move-assignable
- Represent the absence of a sync directory with `std::optional`, not an empty string
- Add `FATStorageArgs` for later use

* Refactor `CartHomebrew` to accept an optional `FATStorageArgs`

- `CartHomebrew` uses it to load an SD card image
- Not passing a `FATStorage` directly because we won't know if we need to load the card until we parse the ROM
- Store the `FATStorage` inside a `std::optional` instead of a pointer
- `CartHomebrew::Reset` no longer reloads the SD card; the frontend needs to set it with the `SetSDCard` method

* Close `NANDImage::CurFile` when move-assigning

- Whoops

* Add `Args.h`

- To construct a `NDS` or `DSi` with arguments
- Mostly intended for system files

* Fix incorrect `final` placement

* Refactor how `DSi`'s NAND and SD card are set

- Provide them via a `DSiArgs` argument in the constructor
- Give `DSi_MMCStorage` ownership of the `NANDImage` or `FATStorage` as needed, and expose getters/setters
- Replace `DSi_SDHost::Ports` with a `array<unique_ptr, 2>` to reduce the risk of leaks
- Store `DSi_MMCStorage`'s disk images in a `std::variant`
- The SD card and NAND image are no longer reset in `Reset()`; the frontend will need to do that itself

* Add getters/setters on `DSi` itself for its storage media

* Remove newly-unused `Platform::ConfigEntry`s

* Use `DSi::SetNAND` in the frontend

* Add `EmuThread::NeedToRecreateConsole`

* Document `NDSArgs` and give its fields default values

* Refactor how system files are loaded upon construction

- Pass `NDSArgs&&` into `NDS`'s constructor
- Use `std::array` for the emulator's BIOS images and the built-in FreeBIOS, to simplify copying and comparison
- Initialize the BIOS, firmware, and SD cards from `NDSArgs` or `DSiArgs`
- Add a new default constructor for `NDS` (not `DSi`) that initializes the DS with default system files
- Embed `FirmwareMem::Firmware` directly instead of in a `unique_ptr`
- `SPIHost` now takes a `Firmware&&` that it forwards to `FirmwareMem`
- Add `Firmware` getters/setters plus `const` variants for `NDS`, `Firmware`, and `FirmwareMem`
- Simplify installation of firmware

* Initialize the DSi BIOS in the constructor

- Change `DSi::ARM9iBIOS` and `ARM7iBIOS` to `std::array`

* Update the frontend to reflect the core's changes

* Remove `DSi_SDHost::CloseHandles`

* Pass `nullopt` instead of the empty string when folder sync is off

* Deduplicate ROM extraction logic

- `LoadGBAROM` and `LoadROM` now delegate to `LoadROMData`
- Also use `unique_ptr` instead of `new[]`

* Oops, missed some `get()`'s

* Move `NDS::IsLoadedARM9BIOSBuiltIn` to the header

- So it's likelier to be inlined
- Same for the ARM7 version

* Remove `NDS::SetConsoleType`

* Add `NDS::SetFirmware`

* Move `GBACart::SetupSave` to be `protected`

- It was only ever used inside the class

* Rename `GBACart::LoadSave` to `SetSaveMemory`

- Same for the cart slot

* Declare `GBACartSlot` as a friend of `GBACart::CartCommon`

* Revise `GBACartSlot`'s getters and setters

- Rename `InsertROM` and `LoadROM` to `SetCart`
- Add a `GetCart` method

* Clean up getters and setters for NDS and GBA carts

* Clean up how carts are inserted into the slots

- Remove setters that operate directly on pointers, to simplify error-handling (use ParseROM instead)
- Add overloads for all carts that accept a `const u8*` (to copy the ROM data) and a `unique_ptr<u8[]>` (to move the ROM data)
- Store all ROM and RAM data in `unique_ptr`
- Default-initialize all fields
- Simplify constructors and destructors, inheriting where applicable

* Refactor GBA save data insertion

- Make `SetupSave` private and non-virtual and move its logic to be in `SetSaveMemory`
- Add overloads for setting save data in the constructor
- Update the SRAM completely in `SetSaveMemory`

* Clean up `NDSCart::CartCommon::SetSaveMemory`

- Move its declaration next to the other `SaveMemory` methods
- Move its (empty) implementation to the header

* Add some comments

* Add Utils.cpp and Utils.h

* Rename some functions in Utils for clarity

* Add `GBACart::ParseROM` and `NDSCart::ParseROM` overloads that accept `unique_ptr<u8[]>`

- The `u8*` overloads delegate to these new overloads
- Also move `SetupSave` for both kinds of carts to be private non-virtual methods

* Finalize the `NDSCart` refactor

- Add `NDSCartArgs` to pass to `ParseROM`
- Add SRAM arguments for all retail carts
- Initialize SRAM inside the constructor
- Delegate to other constructors where possible

* Replace `ROMManager::NDSSave` and `GBASave` with `unique_ptr`

* Make both cart slots return the previously-inserted cart in `EjectCart`

- Primarily intended for reusing carts when resetting the console

* Make `NDS::EjectCart` return the old cart

* Initialize both cart slots with the provided ROM (if any)

* Make `NDS::EjectGBACart` return the ejected cart

* Clean up some comments in Args.h

* Rename `ROMManager::LoadBIOS` to `BootToMenu`

- Clarifies the intent

* Add `ROMManager::LoadDLDISDCard`

* Add a doc comment

* Refactor how the `NDS` is created or updated

- Rewrite `CreateConsole` to read from `Config` and load system files, but accept carts as arguments
- Fail without creating an `NDS` if any required system file doesn't load
- Add `UpdateConsole`, which delegates to `CreateConsole` if switching modes or starting the app
- Use `std::variant` to indicate whether a cart should be removed, inserted, or reused
- Load all system files (plus SD cards) in `UpdateConsole`
- Eject the cart and reinsert it into the new console if applicable

* Respect some more `Config` settings in the `Load*` functions

* Remove `InstallNAND` in favor of `LoadNAND`

* Fix some potential bugs in `LoadROMData`

* Oops, forgot to delete the definition of `InstallNAND`

* Add functions to get `FATStorageArgs`

- Not the cards themselves, but to get the arguments you _would_ use to load the cards

* Refactor `ROMManager::LoadROM`

- Load the ROM and save data before trying to initialize the console

* Clean up `ROMManager::Reset` and `BootToMenu`

- Let `EmuThread::UpdateConsole` do the heavy lifting

* Clean up `LoadGBAROM`

* Remove some unused functions

* Set the default DSi BIOS to be broken in `DSiArgs`

* Respect `Config::DSiFullBIOSBoot` when loading DSi BIOS files

* Remove some more unused functions

* Remove redundant `virtual` specifiers

* Refactor `NDSCart::CartCommon::Type()` to return a member instead of a constant

- One less virtual dispatch
- The cart type is read in `NDSCartSlot::DoSavestate`, which is a path downstream (due to rewinding)

* Remove a hash that I computed for debugging purposes

* Make `ByteSwap` `constexpr`

* Remove an unused `#include`

* Remove unnecessary functions from the NDS carts

- Mostly overrides that added nothing

* Default-initialize all NDSCart fields

* Make `GBACart::Type()` not rely on virtual dispatch

- `GBACartSlot::DoSavestate` calls it, and savestates can be a hot path downstream

* Don't forget to reset the base class in `CartGameSolarSensor::Reset()`

* Remove redundant `virtual` specifiers

* Default-initialize some fields in `GBACart`

* Fix ROMs not loading from archives in the frontend

- Whoops

* Change how the `Firmware` member is declared

* Forgot an include in Utils.cpp

* Rename `FirmwareMem::Firmware` to `FirmwareData` to fix a build error on Linux

- One of these days I'll convince you people to let me use `camelCaseMemberNames`

* Add `override` to places in `DSi_MMCStorage` that warrant it

* Fix firmware saving on the frontend

- Remove `GetConfigString` and `ConfigEntry::WifiSettingsPath` while I'm at it

* Add a non-const `GetNAND()`

Refactor `NDS` and `DSi` to be objects (#1893)
* 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

- 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`

Refactor the GPU to be object-oriented (#1873)
* Refactor GPU3D to be an object

- Who has two thumbs and is the sworn enemy of global state? This guy!

* Refactor GPU itself to be an object

- Wow, it's used in a lot of places
- Also introduce a new `Melon` namespace for a few classes
- I expect other classes will be moved into `Melon` over time

* Change signature of Renderer3D::SetRenderSettings

- Make it noexcept, and its argument const

* Remove some stray whitespace

Move NDSCart-related global state into objects (#1871)
* Move NDSCart-related global state into objects

- RAII will now do the heavy lifting
- Mark some methods as const or noexcept

* Move GBACart-related global state into objects (#1870)

- RAII will now do the heavy lifting
- Mark some methods as const or noexcept
- Once the `NDS` object is finalized, most of these `assert`s can go away

* Make AREngine::RunCheat public (#1872)

- I use it directly in melonDS DS to apply single cheats without using ARCodeFile
- Before the AREngine refactor I could just redeclare the function in my code
- Now I can't

Miscellaneous DSi NAND fixes (#1852)
* Replace some standard I/O calls with Platform equivalents

- I missed a spot when I submitted that PR a few months ago

- Because it uses unique_ptr

* Split DSi_NAND::ReadHardwareInfo into ReadSerialData and ReadHardwareInfoN

* Add a RegionMask enum

* Move DSi NAND patching to the frontend

* Add DSiSupportedLanguageMask

- Not currently used by the frontend, but I use it in melonDS DS

Jesse Talavera-Greenberg d4e51f8060
Refactor DSi_NAND (#1844)
* Refactor diskio's contents

- Change ff_disk_read_cb/write_cb into a std::function instead of a raw pointer
- Add const specifiers as needed

* Refactor DSi_NAND to manage the file system's mounted lifetime with RAII

* Split NANDMount into NANDMount and NANDImage

- NANDImage is used for information about the NAND that doesn't require decryption or filesystem access
- NANDMount is used to actually access the file system
- Both classes manage their respective resources (the NAND file handle and the NAND's mount) with RAII
- Also split the file loading into another function that I will remove in a later PR

* Make NANDMount immovable

* Remove NAND-loading code that I had sectioned off into a function

- Incomplete copypasta
- I must have gotten distracted

* Tidy up NANDImage's initialization

- Don't unmount the disk image if the constructor fails (that's NANDMount's job now)
- Only assign CurFile if the constructor succeeds

* Add some const-correctness

* Move DSi NAND initialization to the frontend

- The NANDImage is now installed via a unique_ptr in DSi

* Remove Platform::DSi_NANDPath

- Not Config::DSiNANDPath; that can still be configured as usual
- The core no longer needs to care

* Make DSiFirmwareSystemSettings a union

- So its bytes can be accessed

* Add a comment

* Use DSiFirmwareSystemSettings instead of raw byte offsets

* Add definitions for DSiSerialData and DSiHardwareInfoN

* Implement SPI_Firmware::DeInit in terms of RemoveFirmware

* Add Firmware::UpdateChecksums

* Fix an incorrect length

* Update all checksums in the firmware after setting touch screen calibration data

* Use the Firmware object's Position methods

* Remove register fields from the Firmware object

* Install the firmware before seeing if direct boot is necessary

* Install the firmware before calling NDS::Reset in LoadROM

* Slight cleanup in ROMManager

* Fix the default access point name

* Shorten the various getters in Firmware

* Add qualifiers for certain uses of firmware types

- GCC can get picky if -fpermissive isn't defined

* Add an InstallFirmware overload that takes a unique_ptr

* Log when firmware is added or removed

* Don't clear the firmware in SPI_Firmware::Init

- The original code didn't, it just set the pointer to nullptr

* Fix a typo

* Write back the full firmware if it's not generated

* Move the FreeBIOS to an external file

* Load wfcsettings.bin into the correct part of the generated firmware blob

* Load BIOS files in the frontend, not in the core

* Fix logging the firmware ID

* Add some utility functions

* Mark Firmware's constructors as explicit

* Remove obsolete ConfigEntry values

* Include <locale> explicitly in ROMManager

- Reallocate the internal buffer if SetPath is asked to reload the file (and the new length is different)

* Remove some stray parens

* Fix some firmware-related bugs I introduced

- Firmware settings are now properly saved to disk (beforehand I misunderstood when the firmware blob was written)
- Firmware is no longer overwritten by contents of wfcsettings.bin

* Slight cleanup

Make the NDS teardown more robust (#1798)
* Make cleanup a little more robust to mitigate undefined behavior

- Add some null checks before cleaning up the GPU3D renderer
- Make sure that all deleted objects are null
- Move cleanup logic out of an assert call
- Note that deleting a null pointer is a no-op, so there's no need to check for null beforehand
- Use RAII for GLCompositor instead of Init/DeInit methods

* Replace a DeInit call that I missed

* Make ARMJIT_Memory less likely to generate errors

- Set FastMem7/9Start to nullptr at the end
- Only close and unmap the file if it's initialized

* Make Renderer3D manage its resources with RAII

* Don't try to deallocate frontend resources that aren't loaded

* Make ARMJIT_Memory::DeInit more robust on the Switch

* Reset MemoryFile on Windows to INVALID_HANDLE_VALUE, not nullptr

- There is a difference

* Don't explicitly store a Valid state in GLCompositor or the 3D renderers

- Instead, create them with static methods while making the actual constructors private

* Make initialization of OpenGL resources fail if OpenGL isn't loaded

* assert that OpenGL is loaded instead of returning failure

Assorted portability enhancements (#1800)
* Introduce some Platform calls for managing dynamic libraries

* Add Platform::WriteFATSectors

* Introduce some Platform calls for managing dynamic libraries

* Add Platform::WriteFATSectors

- Makes it easier to directly include these headers in downstream projects

* Change an include of "../Wifi.h" to "Wifi.h"

* Allow CommonFuncs.cpp to compile on Android

* Tidy up some logging calls

- Use Platform::Log in LAN_Socket.cpp
- Soften some warnings to Debug logs (since they don't necessarily represent problems)

* Add Platform::EnterGBAMode

- Gracefully stop the emulator if trying to enter GBA mode

* Soften some logs that most players won't care about

* Soften some more logs

* Introduce Platform wrappers for file operations

* Fix pointer spacing

* Fix more style nits

* Log the errno when ftruncate fails

* Fix FileSeek offset argument

- With an s32 offset, we couldn't access files larger than 2GB

* Revise Platform::StopEmu to address feedback

- Remove Platform::EnterGBAMode in favor of adding a reason to Platform::StopEmu
- Also rename Platform::StopEmu to Platform::SignalStop
- Add an optional argument to NDS::Stop
- Use the new argument everywhere that the console stops itself

* Rename FileGetString to FileReadLine

- It conveys the meaning better

* Rename FileSeekOrigin::Set to Start

- It conveys the meaning better

* Change definition of FileGetString to FileReadLine

- Oops, almost forgot it

* Rename FlushFile to FileFlush

- To remain consistent with the other File functions

* Add a FileType usage

* Fix line break in FileSeekOrigin

* Document Platform::DeInit

- Some helper functions are exposed for the benefit of consistent behavior among frontends
- Equivalent behavior is maintained

* Fix a tab that should be spaces

Split the cart parsing and loading steps (#1707)
* Split ROMList into a .cpp file

- Its definition in ROMList.h was causing multiple-definition linker errors
- Introduce ROMListSize, since you can't take a sizeof() of an extern declaration
- Mark ROMList and ROMListSize as const

* Update ReadROMParams to accommodate ROMList changes

* Split parsing and loading of NDS ROMs

- Introduce an NDSCartData class for parsing a ROM file
- Introduce InsertROM for loading a NDS cart
- Refactor LoadROM to use NDSCartData and InsertROM under the hood

* Reset cart state and initialize save memory in the NDSCartData constructor

- Otherwise there's no way to know about SRAM-specific attributes before inserting the game

* Add a comment to NDSCartData

* First crack at splitting parsing and loading for GBACart

* Add some logging calls for encrypting the secure area

* Log the XXH64 hash of the inserted NDS ROM

* Log the XXH64 hash of the secure area after decryption

* Add some logging to Key1_LoadKeyBuf

* Re-encrypt the secure area when inserting the cart, not when parsing it

- This way, constructing a NDSCart doesn't imply a read from the filesystem (as is done in Key1_KeyBuf)

* Load Key1_KeyBuf from memory, not from the file system

- Now that the cart's secure area isn't re-encrypted until insertion, we can expect that the BIOS will be ready at this point

* Add some helper query methods to NDSHeader

* Query the DSi region directly from the header instead of checking the ROM again

* Introduce a CartType enum

- So CartCommon::Type doesn't have to return magic numbers

* Reset the cart in NDSCart::InsertROM instead of the NDSCartData constructor

- That way the constructor doesn't rely on the config or on file I/O when loading homebrew
- This keeps the use of global state closer to one place

* Add non-const getters for the carts

* Add InsertROM overloads that accept unique_ptrs

* Fix a comment

* Rename member functions on NDSCartData and GBACartData to adhere to the convention

* Rename members on NDSCartData and GBACartData to adhere to the convention

* Fix build errors on some platforms

* Add NDSHeader::IsDSiWare

* Add a ROMListEntry parameter to the cart constructors

- To allow for looking up details of SRAM or expected ROM size

* Add some new getters to CartCommon

* Use the Header/Banner members instead of globals

* Make CartCommon abstract

- It's not supposed to be instantiated anyway

* Change the signature of CartCommon::Checksum

- It's neither overridden nor mutating

* Add some clarifying comments to NDSHeader

* Delete CartCommon::ROM in its destructor

- ParseROM copies its input and gives that copy to the cart object, so it's okay

* Add some getters to CartCommon

* Refactor NDSCart

- Get rid of NDSCartData
- Get rid of cart-specific global state within NDSCart (so registers are untouched)
- Refactor uses of removed global variables to use the Cart pointer instead
- Refactor ROMInfoDialog's icon functions to accept const arguments

* Return the cart pointer

- So *that's* why it was crashing. Whoops
- Why is this even allowed?

* Refactor GBACart

- Delete CartGame::ROM in the destructor
- Get rid of GBACartData
- Remove some global state

* Mark NDSCart::CartCommon::Type as const

* Slightly refactor GBACart::CartCommon

- Mark Type as const
- Use enum constants
- Make CartCommon itself abstract

* Mark CRC32's data parameter as const

* Mark GBACart::CartCommon::Checksum as const

* Use assert.h instead of cassert

- As demanded by the style guide

* Fix some includes to adhere to the style guide

* Get the ARM9 entry address directly from the header object

* Use more Header fields directly

* Rename some parameters to match the style guide

* Remove some unused includes

* Slightly change NDS_Header::IsHomebrew for clarity

DMA timing renovation (#1207)
* make timers usable for measurement shito without being assfuckingly unreliable

* bürp

* Arisotura can you ever clean up your goddamn code

also regroup the timer code instead of having it split weirdly

* make the set-timing functions a tad less hacky

* congrats Arisotura you made an ass-enum

* add timing region tables, and separate timings for ARM9 DMA (exempt of 3c penalty)

* temp work on DMA timings, not finished

also, did you know? 'increment/reload' is also a thing for the source address

* begin work

* add some of the GBA slot/wifi timings

* complete it, I guess

* make some progress

* getting somewhere

* sdsdfs

* see, Arisotura, was it that hard? blarg.
