  • libc:

    • Fixed an important regression in memcpy() and memset() implementations.

  • Improved file I/O performance:

    • Added support for batch reads and writes of contiguous clusters, improving SD card performance for very large sequential reads/writes.
    • Added fatInitLookupCacheFile(). This allows opting a file into having a special in-memory cache which significantly speeds up file seek operations.
    • Provisionally automatically enabled the in-memory cache for NitroFS files. If you're experiencing slowdowns, make sure to defragment your SD card - this requirement will be loosened in future releases (but it's still a good idea).
    • Integrated profi200's dsi_sdmmc driver, improving reliability and performance for reading from and writing to the DSi's SD card.
    • Optimized unaligned buffer I/O performance for the DSi's SD card.
    • Only cluster table/directory-related reads will now be cached by the built-in sector cache. This allows better use of this sector cache; one can use setvbuf() to enable a larger cache for file I/O.
    • Other minor optimizations have been made throughout the code.

  • Added a new Slot-2 API (arm9/peripherals/slot2.h).

    • Added support for detecting external RAM cartridges (SuperCard, M3, G6, DS Memory Expansion Pak, EZ-Flash variants, EverDrive).
    • Added support for enabling and disabling the data cache on the Slot-2 memory area. Combined with suitable bus speed detection for these cartridges, this allows efficient usage of such an external RAM area.
    • Added support for detecting and using the Gyro, Solar and Tilt sensors available on various GBA game cartridges.
    • Fixed detection of GBA cartridge rumble (WarioWare, Drill Dozer).
    • Modify rumble example to show how to use the new API.

  • DLDI:

    • Moved the built-in sector cache into unused memory occupied by the reserved DLDI driver area. This effectly saves ~20KB of heap RAM for most homebrew.
    • The DLDI driver area size can now be changed by defining the __dldi_size symbol to a value away from the default of 16384, such as 8192 (if your application is highly RAM-constrained - this may break support with some cartridges, however) or 32768 (restores compatibility with MoonShell versions at the cost of an additional 16KB of RAM).
    • The DLDI driver area is now guaranteed to be close to the beginning of the .nds file, which may slightly improve load times.

  • DSP:

    • Add BTDMP and ICU helpers.
    • Refactor crt0.s.
    • Add examples of handling interrupts, including timer interrupts.

  • libnds:

    • Rename some cache helpers for consistency.
    • Fixed a file handle leak that could occur if nitroFSInit() was pointed to an .nds file which does not contain a NitroFS file system.
    • Fixed a rare case in which nitroFSInit() could try reading from the GBA slot on the DSi, causing an exception.
    • Added readFirmwareJEDEC() function to read the ID of the DS firmware flash chip. (lifehackerhansol)
    • Minor optimizations have been done to readUserSettings().
    • Fixed the NDMA_DST_FIX macro definition.
