06/25/24 - Update: Don't want to wait for a proper English Translation of a non-English supported game but want to play the game now? You can try to use the freeware "LunaTranslator" combination text hooker (text grabber) and language translator application (GitHub page | Download page) to machine translate or AI translate the game's native text into English (Note: Machine translation is 1:1, word for word translation. Some ideas may get "lost in the translation". AI translation attempts to mimic a natural speaker's translation of a language into English (I haven't tried this method yet)).
See the verbose "How to" demo video posted by "Daiya" on YouTube (Note: From her dialogue in the video, Daiya seems to be a teenage girl, so try to bear with the "quirkiness" of her dialogue with the viewer [you]. She set LunaTranslator to use AI translation [See the improved English translated, purple text in the screenshot]).
In the past, I personally have used the AGTH (Anime Games Text Hooker application with the Atlas Japanese-English translator application) to try to play untranslated Japanese H-games with machine translation and just discovered this combination text hooker and translator application that supports AI translation (An improvement over machine translation) so, if you have any in-depth questions then it's best to visit the dev, "HIllya51"'s Q&A page on GitHub.
That's a big question that you've asked in such a briefly worded question.
So far, there has been no direct comparison between LunaTranslator and Translumo that's available from other users. Also, I haven't used TransLumo, so I can't compare the two and give you my own personal opinion about them. You have to realize that all of this is still relatively new technology and we are only at the beginning of this new revolution in language translation.
However, I can tell you that LunaTranslator can be set to use ChatGPT as one of many external AI translation tools that it uses simultaneously. ChatGPT is a Generative AI translation tool that tries to achieve a more contextual, natural translation (Perhaps almost, but not 100% perfect, as though a professional linguist had performed the translation). From what I can see on Translumo's GitHub page, Translumo uses it own(?), built-in Ai translation tool (This may need future clarification) to achieve near-natural translations.
I tried to find a video on how to use Translumo but found none, so I don't know whether it can also be set to use multiple AI translation tools simultaneously like Lunatranslator or if it only uses its own built-in, powerful AI translation tool or engine. More information about Translumo is needed before any comparison can be performed. If you've used Translumo before, perhaps you can share your experience with using it, with the rest of our community here and even compare it to Lunatranslator based on what I've revealed so far about Lunatranslator.
My advice: Ar Tonelico 1 and 2 for PS2 with PCSX2 emulator and that's all you need, all the other games are garbage, no waifu choice, bad story and repetitive gameplay to the point of disgust
The PC version of this game is only available with Japanese support. However, you can try to play this game in English using "LunaTranslator" with AI translation. See my above post!

Translumo uses several OCR engines at once to recognize text and supports the following online translators: DeepL, Google, Yandex, Papago.
