* Simplify the SRAM's representation in `NDSCartArgs` (#1914)Jesse Talavera2023-12-15
| | | | | | | | | * Simplify the SRAM's representation in `NDSCartArgs` - I overthought this one. - I could've just checked `args && args->SRAM`, but then some other poor bastard might make this mistake. - Don't mix `pair`, `optional`, and `unique_ptr` all at once, kids. * Fix a `nullptr` read
* Fix detection of native NDS ARM BIOS images (#1910)Jesse Talavera2023-12-15
| | | | | | | | | | * Fix detection of native NDS ARM BIOS images - Instead of checking for built-in BIOS images, now the altered methods check for native ones - The CRC32 must match exactly; patched BIOS images will result in `false` * Encapsulate `NDS::ARM9BIOS` and `ARM7BIOS` - Also compute the checksum only when setting the BIOS
* Make the initial 3D renderer configurable via `NDSArgs` (#1913)Jesse Talavera2023-12-15
| | | | | | | * Allow 3D renderers to be created without passing `GPU` to the constructor * Make the initial 3D renderer configurable via `NDSArgs` * Fix a compiler error
* Support emulating R4 Revolution/M3DS Simply cartridges. (#1854)Adrian Siekierka2023-12-15
| | | | | | | | | | | | | | | | | | | * Support emulating R4 Revolution/M3DS Simply cartridges. * NDSCartR4: Write state information to savestate file. * NDSCart: Use strncmp instead of strcmp for R4 detection. * NDSCartR4: stylistic improvements * NDSCartR4: rudimentary Ace3DS support * NDSCartR4: fix boot when firmware enabled * NDSCartR4: Fix for namespace changes --------- Co-authored-by: RSDuck <RSDuck@users.noreply.github.com>
* Sprinkle `const` around where appropriate (#1909)Jesse Talavera2023-12-12
| | | | | | | | | * 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
* fix default emu settings tab (#1912)Jaklyy2023-12-12

|
* Soften restrictions around `ARMJIT_Memory::RemapNWRAM`Jesse Talavera-Greenberg2023-12-08
| | | | | - If in NDS mode, return instead of `assert`ing - Use `static_cast` and `ConsoleType` instead of `dynamic_cast`
* FreeBIOS: Ensure upper 16 bits are cleared in the initial crc16 value.CasualPokePlayer2023-12-06
| | | | | Fixes Castlevania: Dawn of Sorrow's checksumming which uses crc16 swi and has garbage in the upper 16 bits of r0. The official BIOS would seem to implicitly clear these upper 16 bits.
* Remove the last `ConfigEntry` state (#1902)Jesse Talavera2023-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
* Use a `constexpr`-friendly cosine implementation (#1903)Jesse Talavera2023-12-05

* Refactor how save data (including SD cards) is initialized (#1898)Jesse Talavera2023-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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()`
* Slight cleanup to SPU (#1900)Jesse Talavera2023-12-04
| | | | | | | | | | | | | | | * Move `SPUChannel` and `SPUCaptureUnit` to be stored inside `array`s instead of allocated separately * Default-initialize most of `SPU`'s fields * Generate the interpolation tables at compile-time with `constexpr` - Now it's faster and thread-safe * Slight cleanup in SPU - Iniitialize most fields in the class declaration * Mark `SPU` as `explicit`
* Clean up the 3D renderer for enhanced flexibility (#1895)Jesse Talavera-Greenberg2023-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Give `GPU2D::Unit` a virtual destructor - Undefined behavior avoided! * Add an `array2d` alias * Move various parts of `GPU2D::SoftRenderer` to `constexpr` - `SoftRenderer::MosaicTable` is now initialized at compile-time - Most of the `SoftRenderer::Color*` functions are now `constexpr` - The aforementioned functions are used with a constant value in at least one place, so they'll be at least partially computed at compile-time * Generalize `GLRenderer::PrepareCaptureFrame` - Declare it in the base `Renderer3D` class, but make it empty * Remove unneeded `virtual` specifiers * Store `Framebuffer`'s memory in `unique_ptr`s - Reduce the risk of leaks this way * Clean up how `GLCompositor` is initialized - Return it as an `std::optional` instead of a `std::unique_ptr` - Make `GLCompositor` movable - Replace `GLCompositor`'s plain arrays with `std::array` to simplify moving * Pass `GPU` to `GLCompositor`'s important functions instead of passing it to the constructor * Move `GLCompositor` to be a field within `GLRenderer` - Some methods were moved up and made `virtual` * Fix some linker errors * Set the renderer in the frontend * Remove unneeded `virtual` specifiers * Remove `RenderSettings` in favor of just exposing the relevant member variables * Update the frontend to accommodate the core changes * Add `constexpr` and `const` to places in the interpolator * Qualify references to `size_t` * Construct the `optional` directly instead of using `make_optional` - It makes the Linux build choke - I think it's because `GLCompositor`'s constructor is `private`
* Refactor `NDS` and `DSi` to be objects (#1893)Jesse Talavera-Greenberg2023-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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`

* Move all core types into namespaces (#1886)Jesse Talavera-Greenberg2023-11-25
| | | | | | | | * 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

* Refactor the GPU to be object-oriented (#1873)Jesse Talavera-Greenberg2023-11-09
| | | | | | | | | | | | | | | | | * 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)Jesse Talavera-Greenberg2023-11-09
| | | | | | | | | | | | | | | | | | * 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

* Fix regression caused by change to front face polygon culling (#1820)Jaklyy2023-11-07
| | | | | | | | | * fix regression with facing view Only the check for a polygon being counter-clockwise is supposed to be <= * only use dot < 0 for 'cull front face' polygons this is the fix.
* Also exclude .note.GNU-stack section on Windows arm64Nadia Holmquist Pedersen2023-11-07

* ArchiveUtil: use signed return type instead of unsignedRayyan Ansari2023-11-06
| | | | | | | | The ExtractFileFromArchive function can sometimes return -1 on error, however the function's return type was specified as u32, which would mean that it would instead be represented as the maximum value. Change the function's return type to the signed s32 instead, and correct uses.
* Fix some memory leaksRayyan Ansari2023-11-06
| | | | | | Free some objects that were allocated with new but not deleted, and in one case, do not set a pointer to nullptr before deleting, as this results in a memory leak due to memory allocated not being freed.
* ROMManager: initialise filedata to nullptrRayyan Ansari2023-11-05
| | | | | | | | | If a user manages to open a file as a ROM that is greater than 1 GiB, it will cause a segmentation fault (a crash) in LoadROM due to a delete being called on an uninitialised pointer, which is undefined behaviour. Initialise filedata to nullptr to prevent this, as deleting a null pointer is defined as a no-op.
* CameraManager: wait for camera to be loadedRayyan Ansari2023-11-05
| | | | | | | | | | | | | | | In QCamera in Qt 5, the camera is required to have been loaded before querying its settings and resolutions. Doing so without loading being finished would result in the returned list being empty. See https://doc.qt.io/qt-5.15/qcamera.html#supportedViewfinderSettings Add a QEventLoop that waits for the state to change from Loading to Loaded before supportedViewfinderSettings() is called to ensure that valid information is returned. (Fixes my camera being blank in preview, same issue also presumed to occur when camera is needed in game, fix tested on a USB camera on a Linux system and Qt 5.)
