main.cpp:182-211 picks the portable or Qt config folder. dsi_sd_card.bin reads as dsisd.bin there, the DSi.SD.ImagePath default (Config.cpp:120).

|
FreeBIOS fallback for DS mode (NTR), while DSi mode requires all native files.
|
|
Libretro fork based on melonDS ~0.9.x era, validates size only.
|
|
Upstream adds CRC32 validation on BIOS files (MemConstants.h).
|
|
DSi SD card emulation controlled by melonds_dsi_sdcard core option.
