Well, it seems none of them is present in the data... They haven't even updated the E-code messages file. Edit
: They actually have, in 057aa975bdd2b372fe092614b0f4399e, there is a file called "ii_dpp_chase.text", but still I have unreadable characters. (http://imgur.com/XzYDrpG
Also what are you using to open the .lua files ? I'm actually using Wordpad and this is usually what I see, bunch of unreadable characters, then readable, then unreadable etc... Should I download another software or something like this or does it actually happen to you ?
