Profiles that read two repositories, a libretro port and its upstream, now prefix each citation with source or upstream, decided by which tree carries the cited value at its pin. The emulator pages use the word to tell libretro glue, emulator code as the port carries it, and the upstream emulator apart.

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.
