  • Setup complexity – New users often struggle with paths, missing dsi_nand.bin vs nand.bin naming, and the required dsi_bios9.bin / dsi_bios7.bin alongside it.
  • Feature incompleteness – Wi-Fi and DSi Shop connectivity are still experimental; not all DSi system apps work perfectly.
  • Larger resource usage – Emulating NAND access adds overhead compared to DS mode.
