Switching from Gateway to CFW

Hey want to change my Gateway setup to a CFW Setup.
I already downloaded GSEH an made a backup of some games but the app won't show my Pokemon Sav files and some other games, how can i backup these games? Do i need to convert the saves before injecting them to the installed CIA's?
My 3DS is on firmware 9.0.0-20E. So i only need to run Soundhax and install boot9strap etc?
I want to capture my Screen which CFW do i need for it?

Thank You!

I found this Tutorial.
I'm not sure if i understand it correct. I need to copy my 3ds file to the 3ds sd card an than use JK Save Manager to extract my sav file and than i need to rename it to 0004000002C23200 move it to the root of my sd card and import it to my cia?

 

You mean i install the Cias on my Emunand and than create a sav file to swap with my Gateway Sav? Guess this won't work ._.

I'm using a New 3DS XL i think i downgraded it in the past i don't remember anymore

 

I will give it a try. It's currently installing (23%) i will edit the post after it installed.

Edit: @Hunter Game is not starting on my Emunand. Guess i will try this https://gbatemp.net/threads/importing-gateway-saves-to-cia-games.425743/

 

Yes but i thought maybe someone with the same problem will more likely read this topic. And there are still two open questions in the other thread :/
