A note about compatibility: it should work on the same computers than the japanese version. It should work with non-japanese locales as long as there isn't any special characters in the path. I think it should work with nvidia drivers while the original game doesn't, but I couldn't test. I absolutely don't know whether it works on Wine or not. And it works on Windows XP!
Thanks to everyone who helped with this project. Thanks to Riatre for its 135tk, which I upgraded and reused for this patch, and thanks to rr-, who made an unpacker for the ULiL archive (
https://github.com/vn-tools/arc_unpacker) and cracked some anti-hack stuff. On the translation side, thanks to the Touhou wiki (en.touhouwiki.net), and thanks to Clarste for translating the texts that weren't on the wiki. Thanks to Gamer251 for the image editing. Thanks to the thcrap team for the beta test and some design suggestions.
And, finally, many thanks to Splashman, for some translations, for image editing, and for taking care of everything related to the archive files: searching for translatable content, replacing the texts in the various files, going through all the texts to ensure they're correctly displayed, making the releases etc. You really helped a lot on this.
Ah, and of course, thanks to ZUN and tasofro for making the game, and also for not releasing hundreds of updates (1.34b from HM was a nightmare...).
Also, during this patch, I documented the technical things I made, Splashman documented things regarding the file formats, and I explained things about some files formats I remember from HM. We decided to document all that, first because it has been useful for us to have an unique points containing a remainder for everything, and secondly because it could be useful for other people (for example, the documentation about the TFPK format is only for other people, my memories and my source code are enough for me). You can find all this documentation here:
