# melonDS DS — Nintendo DS/DSi (libretro, newer fork)
# ref: JesseTG/melonds-ds, docs.libretro.com/library/melonds_ds
# Prefers files in "melonDS DS/" subfolder. DS mode has HLE fallback.
# DSi mode requires real BIOS + NAND dump.
#
# doc vs source: docs use bios7.bin/bios9.bin (NDS) and dsi_bios7.bin/
# dsi_bios9.bin (DSi). The older melonDS core uses the same names.
# Repo stores NDS ARM7/ARM9 as biosdsi7.bin/biosdsi9.bin (DSi dumps that
# also work for NDS). The md5 in docs (df692a80/a392174e) are for the
# smaller NDS-only dumps, different from the DSi dumps in the repo.

notes: |
  Newer fork of melonDS for libretro with DSi support.
  DS BIOS files are optional (built-in FreeBIOS used as fallback).
  DSi mode requires all four DSi-specific files.
  Core searches "melonDS DS/" subfolder first, then system root.
