Homebrew How to Start OOT homebrew?

[MrYoshida]

I started the Dsiware downgrade on my 3DS and for some reason, the steel driver game for the homebrew entry didnt transfer over. So, i bought oot for a homebrew entry and when i downloaded the files to set it up, there were many files. I dont know which one to pick. Do i choose the one for 10.3 because isn't that the version im suppose to be downgraded to after completing all the steps? or do i use the verison that it says in my settings. I have a N3ds btw
