I've always wanted to make my own splash text resource pack
So I did it.
You can edit the file how you want. All you need to change the text is Notepad++, you can download it here: https://notepad-plus-plus.org/downloads/
I'll keep updating this pack whenever I add new phrases
The pack may say it's for an older version of Minecraft, but it's only the splash text so it doesn't matter, just load it up. Your PC won't blow up or anything lol.
I made a little showcase of the pack on my YouTube channel here if you're interested: https://youtu.be/LYCj_c-IMh4
