I need help to make a translation patch

[Maruki94]

Hello, I want to make a spanish translation patch for the Angel Beats visual novel, but I don't know what the process is to make a patch, and I would like to know the process.

I have been looking for information both in my language and in english, but I have not found anything that goes in-depth into the topic of making a patch or hacking a visual novel to get the scripts out.

I asked someone who was previously affiliated with Alka but he told me that you need to go to Alka since they have the tools for it already prepared. You find them here: https://alkatranslations.com/
