Flashcart OS (N) is the Novice version of Flashcart OS. It was formerly called Flashcart OS: Slot-1 Edition, which is a homebrew menu with an integrated .nds loader. The menu is M3 simply/R4DS based and has to be patched with a DLDI file of your card. You can skin this file with a M3 ds simply/R4DS skin, that you have renamed and converted to the .gif format.

Flashcart OS: N 2.1 was submitted to the NEO Spring Coding Compo 2008 and ranked 10th.


  • Supports R4/M3 Simply skins that are converted to .gif.
  • Has a file browser for booting NDS files.
  • Boots to MoonShell (moonshell.nds).
  • Boots to GBA mode.


Extract file and DIDL patch it.

If you use a Datel Games 'n' Music, use the pre-patched bootme.nds file (for Moonshell user, rename MoonShell to _DS_MSHL.nds and put it in the fshl folder in order to boot).

Place your skin in the fshl folder. Place on the root of your card.
