I thought some years ago I might try my hand at translation, since there seems to be no work being done by well, anyone (fan or official) on translating Otomimi Infinity.
Last night, being bored and nothing better to do, I figured I'd at least look into it.
Tried using mjarc (https://proger.me/vn/old/#majiroarc+v1+and+v2+tools) which seems to extract .mjo and .utf fine, I can then edit, but doesn't seem to repack into .arc at all
Tried using arc_conv which again extracts the .mjo seemingly fine, but on using text_conv, does not correctly display japanese characters (though I did change my locale back to English before thinking about quitting, which I then didn't do -- though mjarc still extracts the characters correctly in the utf files)
Was also hoping to figure out how to work with rct/rc8 files if possible (as mentioned under the Majiro heading in the first post here, https://forums.fuwanovel.net/topic/17841-script-extraction-thread/?do=findComment&comment=453725 which mentions tools needed as "majiro-stuff", with a nonfunctioning link; and when I search for majiro-stuff I find something on GitHub which I can't for the life of me get to work at ALL).
Apologies if I'm being super thick here, but I spent hours last night trying to get started on this and running into various walls.
