Let the punching ghost do all the work.
No. Think of them as two different games. You can't use super mario 64 ds codes in New super mario brothers.
If it's New Super Mario Brothers DS, when you're on the file selection screen, before you pick the file, hold down L+R, then while choose the file. This does work,you should hear a voice say "Luigi."
every time you complete a dark castle or spend 5 starcoins to get a mushroom you can save the game.
(.Y.)
yes but only a few like super Mario world redrawn new super Mario ect. the only ones that i know that don't work are super Mario bros 3 redrawn and wario's world. (i use snemuldsv0.6)
I am afraid it doesn't.
its really easy. you can use luigi the same way as in new super Mario bros. For those who don't know do this:select file hold L and R at the same time and then press A on the file you would like to use. if this doesn't work maybe you aren't pressing them hard enough or one of the L or R buttons don't work
Once you have unklocked Mario and see the light change into Mario and look into the light with Mario- oh and its in the castle then youll be there.
Of course! For example: Mario Party DS, New Super Mario Bros DS, Mario Kart DS and a lot more
