You can try running it from the ROM menu.
ok i will do so after i have installed TWiLight Menu which i'm trying to do now. by the way how is the compatibility for booting DS games without Flash Card ? is Flash Card still the best option ? i have R4i 3DS

1. Extract the "_nds" folder, and the "boot_fc.nds" file, to the flashcard's microSD Card root. Also make a copy of "boot_fc.nds", and rename the copy to "boot.nds".You can try running it from the ROM menu.
but the TWilightmenu.zip already contains a boot.nds do i still need to rename the boot_fc.nds ??
