A few days ago I discovered that the French version of SaGa Frontier 2 from Squaresoft has perfectly visible and editable texts. I have already done tests and I already have someone who will be in charge of the translation, but We would like to have a tool that allows us to edit the texts more easily. I don't need it to be a very sophisticated tool or one that allows me to move the text boxes, it's enough for me that I can edit the texts comfortably.
Here I leave a video as a sample of what can be done: https://www.youtube.com/watch?v=Aukysw6qA04
Try find graphics with Timviewer using "scan raw".
Btw sometimes the font can be compressed.
Bad news. I just tried the Tim Viewer like you said but the image with the font still doesn't show up. I think the image is compressed.
