have you a list of updated dialogs? maybe i'll try to translate it to IT and release an italian version of hack
I'm working on a FR translation right now myself^^
You need to dump the game with braindump, then extract the romfs folder with ASia81's tool then use use pk3ds to extract the GARCs (You need to change 0/7/6 and 0/8/4 for IT language).If you want though, you can just edit the files in the archive I attached and send it back to me, I'll do the romfs building.
Here's my setup :
I use Notepad++, in the same window open "NeoXY_gametexts_en" & "NeoXY_gametexts_it" on one side and "XY_gametexts_en" & "XY_gametexts_it" on the other.
Then you can use a plugin for N++ called "Compare" (find it in Plugin > Plugin Manager) to compare "XY_gametexts_en" to "NeoXY_gametexts_en", and everytime you find something that's different edit "NeoXY_gametexts_it" so that it translates the EN version.
Do the same for storytexts.
(The "NeoXY_gametexts/storytexts_it" files I attached are just a copy of the vanilla files, do it however you want but that's the files you'll need to edit if you want to make a translation)
I've also attached pngs for title screen/push start, if you want to edit them too (especially if you want a custom "push start" button, you should probably leave the title screen as it is if you're not an artist^^) ; along with my french files as an example (I translated them already, but I need to do corrections yet).
Last but not least^^ Note the "\n", "\c\n" & "\r\n" characters in your texts, because they are essentials.
\n means the text after goes on a new line
\c\n means the same except it will go on a new textbox (you'll have to press A ingame to make it appear)
\r\n seems to make the text go in a new textbox, but without you needing to press A (just keeping it pressed), but I'm not really sure of this one.
You should always be careful that you don't put too much characters on the same line (~50 characters max.) or your text will be distorded/cut ingame. Also, textbox ingame only have 2 lines so if you have 2 \n in the same textbox it will scroll (line 1 disappear, line 2 & 3 visible).
EDIT: file is too big, so here's the link on my Gdrive :
