Trouble reading scripts

Hi, I`d like to try translating a game named ラブラブル (http://vndb.org/v5734) since it should be quite easy, and my japanese is not great but after extracting the files with crass I got some files with .yks extension, and I can`t seem to be able to read it...I tried opening it with notepad++ and converting it to utf8, sadly with no result. As I understand the extension stands for Yuka Compiler Script, is there anyway of reading and editing it and if so can anyone tell me? Thanks in advance and hope I posted this in the right place.

Ok, so after a lot of reading and researching I understood what I need to do, but I don`t know exactly how to find the address which I need to xor in order to make the scripts ready for reading and editing. A little help would be great....

Yeah, I guess you`re right, though I didn`t mean for that title to annoy anyone...it`s just that I`ve been trying non-stop to find the xor key...

okay...I took a check on it but it not quite difficult.....
anyway the scripts are xored by 0xAA only thing is dumping the scripts and also the images are just png the ykg I mean... and the packing and extracting is very quite simple....
