aisatsunin:
If you are getting garbage instead of tranlations (・あ・・・れ・・うぇ..) then you probably just forgot to insert font files -- they are in fonts directory of patcher, named 30.png..38.png. If you're not getting any change in game at all, confirm it and we'll dig deeper.
To test that everything's working fine, try to insert script 1694.txt; it's the script of the very first event that happens in game (so just select new game in main menu, and you'll see translated text after intro).
If you want to contribute, you're more than welcome; there can never be enough free manpower. There is a guide at
http://tsukuru.info/tlwiki/index.php?title=Idolmaster_SP. To start contributing just edit pages with script text (all listed at
http://tsukuru.info/tlwiki/index.php?title=Idolmaster_SP:PS).
About Japanese lines in scripts (you may notice that they all start with hash (#), which means they are silently ignored by the patcher program), no, you don't need to remove them; you are encouraged to leave them as they are. Their purpose is to let other translators easily compare original and modified text.
