From 5bfe51e670bb0806b254144cbe4c60d3f914c735 Mon Sep 17 00:00:00 2001 From: Jesse Talavera-Greenberg Date: Mon, 18 Sep 2023 15:09:11 -0400 Subject: Refactor the core's handling of firmware and BIOS images to rely less on the file system (#1826) * Introduce firmware-related structs * Fix some indents * Move the generated firmware identifier to a constant * Document the WifiAccessPoint constructors * Add some constants * Remove a stray comment * Implement Firmware::UserData * Add Firmware::Mask * Document Firmware::Buffer * Add a Firmware constructor that uses a FileHandle * Set the default username in UserData * Update the UserData checksum * Forgot to include Platform.h * Remove some redundant assignments in the default Firmware constructor * const-ify CRC16 * Replace the plain Firmware buffer with a Firmware object - Remove some functions that were reimplemented in the Firmware constructors * Fix some crashes due to undefined behavior * Fix the user data initialization - Initialize both user data objects to default - Set both user data objects to the same touch screen calibration * Follow the DS logic in determining which user data section is current * Remove an unneeded include * Remove another unneeded include * Initialize FirmwareMask in Firmware::Firmware * Use the DEFAULT_SSID constant * Add SPI_Firmware::InstallFirmware and SPI_Firmware::RemoveFirmware * Move a logging call to after the file is written * Add a SaveManager for the firmware * Touch up the SPI_Firmware::Firmware declaration * Move all firmware loading and customization to the frontend * Call Platform::WriteFirmware when it's time to write the firmware back to disk * Fix some missing stuff * Remove the Get* functions from SPI_Firmware in favor of GetFirmware() * 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 explicitly in ROMManager * Fix up some includes * Add Firmware::IsBootable() * Add a newline to a log entry - Whoops * Log the number of bytes written out in SaveManager * Mark FirmwareHeader's constructor as explicit * Clean up GenerateDefaultFirmware and LoadFirmwareFromFile - Now they return a pair instead of two by-ref values * Refactor SaveManager a little bit - Manage its buffers as unique_ptrs to mitigate leaks - 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 --- src/NDS.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/NDS.h') diff --git a/src/NDS.h b/src/NDS.h index 571952d..e81e952 100644 --- a/src/NDS.h +++ b/src/NDS.h @@ -240,6 +240,8 @@ void SetARM7RegionTimings(u32 addrstart, u32 addrend, u32 region, int buswidth, void SetConsoleType(int type); void LoadBIOS(); +bool IsLoadedARM9BIOSBuiltIn(); +bool IsLoadedARM7BIOSBuiltIn(); bool LoadCart(const u8* romdata, u32 romlen, const u8* savedata, u32 savelen); void LoadSave(const u8* savedata, u32 savelen); -- cgit v1.2.3
