Capture2Text is an excellent program for hooking text in mangas that also works in games.An alternative is an OCR(Optical Character Recognition) site.I found that ocr.space does the best job for japanese mangas.
After you obtain the text you just paste it into a translator.I don't recomment google, the site I've successfuly used to get the best translationis deepl.com! I hope this helps!
