Agent: For both VNs and normal games (like persona, yakuza, dragon quest etc...). https://github.com/0xDC00/agent
Here you can see what games are supported by agent. https://github.com/0xDC00/scripts
Hook Any Text (HAT)
https://github.com/MX-Futhark/hook-any-text
HAT is a plugin for Cheat Engine that automatically converts hexadecimal data into readable strings. This project aims at providing a way to hook text when other widely used text hookers fail to do so. Therefore, it might not be as user-friendly as what is expected of such tools, and the result might not be as clean as you would expect. However, you should be able to hook the text of a vast range of games, particularly on emulators.
*You are supposed to use Textractor and Agent with a texthook page so you can do your yomichan lookups. or you can use the yomitan search page with the "clipboard monitor" enabled.
A texthook page is simply a blank page where the text in your ¹clipboard goes to.
