There's 52k lines that have to be translated, I started on a translation early in 2021 and got to around 30% done. That was me doing it on average of 4h every 2-3 days, there's a LOT to translate. OmegaT helps a bit, makes it faster but it's still a lot to do. If you're doing it by hand, you can clear about 3k entries every 4-5hr.
Nope not really. You could use
Libellule's translator RPGMV_hook, if internet is the problem either bandwidth or due to censorship. You could also use a live translator service via Textractor(bing/google/yandex/etc), or use a local-loopback using Sugioi+Textactor for on-the-fly translations.
