Hello. I am an Italian translator and do semi-automatic translations for the Italian forum community.
Taken by the curiosity of this program, I'm testing since almost a week the ZenpyPro version and I'm following their Discord channel to solve some problems or limitations that should arise.
I consider this All-In-One program really great for those who want "done and finished" translations without having to wait for translations done by translators who translate for their community.
Compared to other free, public domain All-In-One programs, including ZenpyFree itself, I consider the ZenpyPro version to date to be the best All-In-One tool for translating Renpy games, thanks to the possibility to customize the translations made and to intervene in some stages of the translations more thoroughly.
The level of customization in this version also makes it a great tool for translators who translate for their community, as you can make corrections directly from the program or by putting your hand in the scripts as you usually do.
Translation speed is lightning fast, translating the game A Mother's love, a very complex game with tens of thousands of dialogues, took just under 3 minutes using the Google online translator.
Afterwards, if you want you can do some post-processing to refine the translation. However, I think this is of more interest to translators who translate for the community, not just for them.
I recommend this version of the program for translators or more demanding users.
