I'm working in a private github repo right now so the only updates are gonna be on my Itch.io page when I feel like there's enough progress to an update post. I also saw my game linked on the School Days subreddit (which is where JAST USA seems to have first found out about it) so I might post updates there as well.
As for the progress itself, I actually started translating a few months ago and picked it up again recently. Episode 1 is now fully translated (120 files total), with Episodes 2, 3, and 4 still ahead (about 1911 files left to go).
I'm not too interested for the other games since they are spin-offs and I doubt they run on FORIS so I'd have to make a new engine for that.
Also, Island Days is for Nintendo 3DS and I don't even wanna start to think about how I'd re-engineer that.
I also hope Cross Days would get a remaster someday, since that'd be the perfect chance for an official English release. You can tell the original was rushed, it barely works & there are tons of leftover files, even unfinished pre coloring stage line art still sitting in the game data. XD
Also, it's kinda funny to me how we're discussing School Days in the comments of this completely unrelated tool I made.
