Is there any other way of injecting mods directly to the game other than FTPii U everywhere? It works, but it's really slow (especially with the TitleBG.pack), and some things don't ever transfer successfully. I know that you could use Loadiine GX2, but people say the load times are THE actual worst, and it's really hard on your SD card.
"SDCafiine" is the middle way between fast and slow load, it is not the fastest way like FTP injection mode but it is not the worts like Loadiine mode.
If you read the Tutorial for FTPii Injection, you should've downloaded the file list, and if you read the post, some files are imposible to replace. I actually did that Injection and I don't have any problem with the game. It is slower that other methods for "inject" but is very fast in the load screens.
