ftpd VS ACNH-BCATs

you can interact with your SD card without taking it out using FTPD

Run sys-ftpd or ftpd and access your files from a computer using an FTP client

Use FTPD for quick file transfers to the 3DS over wifi without the need of removing the SD card. Available in the Universal Updater app.

I don’t have what you’re looking for but I have a solution for your screwdriver problem. Here is a video explaining how it works.

I have ftpd on my 3ds and I use FTPCafe FTP Client on my Android phone, then i download DS roms on my phone, after this I share internet (hotspot) to my 3DS, start ftpd on it, then put the IP that it says on the phone.

Yeah, pretty much. You can make your own BCAT if you want to get fancy but I'd recommend just using the ones provided by Agronomru

As the title says, I was following this tutorial to get to play events in animal crossing. At some point however, it asks me to synchronize my time by connecting to the internet. This is on my emummc so it's pretty dirty. Would doing this get me banned? Do I really need to do this?

Before I did all this I made a backup with JKSV. Then I was updating. Then I injected the BCAT (provided by this helpfull fellah GitHub - agronomru/ACNH-BCATs: Animal Crossing New Horizons BCAT Events )

I decided to switch from SXOS to Atmosphere. Best decision so far. But after I recovered the ACNH savegame the Version won’t say 1.9.0b, but only 1.9.0. I then tried to recover BCAT files with help from here https://github.com/agronomru/ACNH-BCATs But still no „b“.
