Someone on the old forums made a topic (in the fanworks forum, for some reason) about this for me. Thanks, I guess. Now it's finished, so I guess I'll make the topic.
Touhou Mother is a Japanese RPG Maker 2000 fangame created by S(-chan, -teru, or just plain S). From the title(s), you should be able to guess the basic idea: Mother/Earthbound with Touhou characters. I found it on Nico one day as a popular Games video, and later, I figured I could translate some of it pretty easily since it's all kana (Mother-style). It ended up becoming a pretty huge project, but now it's done!
S made a series of videos of him playing through the game as he made it. (There wasn't actually a public version at all until Video 17 of 30.) I did the same thing as I translated it. You can see my videos
here. Keep in mind that some of the videos, especially earlier ones, are outdated in some ways. Mostly quality of translation.
I released 1.0 a few days ago, but I didn't really do any testing because I'm impatient with myself I guess. After doing a full test playthrough and a significant amount of retranslation, I've just released 1.1.

May 20th: Updated to 1.11. Not many changes, so you can download just the changed files and "patch" 1.1 with them.
July 20th: Updated to 1.111. Mostly going through and finally making sure I was satisfied with the translation of all major conversations. Way more changes than 1.11, but I still made a patch that'll work with either 1.1 or 1.11.
August 5th: Updated to 1.1111. I finished transcribing everything for the script, so absolutely all translation should be acceptable. I swear this'll be the last one unless I REALLY messed something up.
