My friend, I can translate it myself. As long as you have the texts in native English and send them to me by email. I'll translate it and send it back to you so you can publish it in your game. The situation of Xenosaga in Brazil is as follows: Xenosaga I and II on ps2 are 100% translated. Xenosaga 3 I believe will never happen. The group that did the translations seems to no longer be interested or respond to messages. I don't speak English but the English to Brazilian Portuguese translation tools are close to perfect.
Do you have Discord? If yes, follow the public invitation link to Files from the Zohar here: https://x.com/DailyXenoSeries/status/1682714606563622916
On that server, you can find me as CycloneFox and you should be able to send me personal messages then, so we can talk.
