3DS CFW+Homebrew: Still no Pokémon dump Edition

How can I tell if I properly installed the filter.txt for JKSV?

JKSM*

In the guide, right at the start, when I need to access a website to enter decrypt9, my browser crashes every time. I have been trying for almost 3 hours now, is really that hard?

Are you on 9.2? Tried initializing the browser savedata? The only exploit that took longer than a few minutes to work was sliderhax

I'm on 4.2 Sysnand (it's a friend's console, he had rxtools but he can't access emunand anymore so he asked me to fix and I'm trying to arm9lh it).

The exact step from the guide I'm stuck is this one: plailect.github.io/Guide/decrypt9-(browser)

>dukesrg.github.io/?Decrypt9WIP.dat
>go.gateway-3ds.com/
>reboot.ms/3ds/load.html?Launcher.dat
>dukesrg.dynu.net/3ds/rop?GW17567.dat&Launcher.dat

What can I do to allow Freeshop or CIAngel to recognize undub games? I want to get the DLCs for SMT: Apocalypse undub, but the game doesn't appear in Freeshop or CIAngel.

Install the dlc manually

Tried reseating it several times, didn't work. Tried reformatting the card to FAT32, didn't work. Tried another card I use in my PSP, didn't work.

Always just gives me a black screen when I try to launch it. Did I just get a bad flashcart?

Do you need to extract anything to the SD card for it to work? Pretty sure that's the case with the Gateway clones.

Yes, I did what this guy said to do for the R4:
gbatemp.net/threads/getting-started-with-ds-flash-carts.293671/

I'm right between what every solution I find on Google is about. It's always either solutions for it not showing up on the home screen, or for the loading screen being forever. It shows up on the homescreen for me, but I never even get to a load screen. Just a black screen.
