I admit to being a bit lazy when it comes to making my mods translation friendly, but I've finally been prodded and poked enough to get around to it. I'm going to attach a .zip with the .tra files from both Sirine's Call and Indira here for people to translate. If other mods get released (at least, PPG-hosted mods), I'll stick the .tra's in here, too.
The .tra files related to Sirine's Call are:
_sil.tra
_ardrou.tra
pirates.tra
setup-sirinescall.tra
So far it's in english and german (when I get around to updating it in a few minutes), with a french version is underway.
For Indira, we have:
indi.tra
murnethbanter.tra
setup.tra
So for it's in english and french.
If you want me to update this thread, indicating that a translation is being worked on (or done), let me know.
