Need help identify Yulgang files viewer/exporter

[krhuy1996]

Hi, Yulgang online is an really old game, so I don't think its encryption is too complicated or may be there is no encryption at all for the files
I need help identify the view and exporter for these files, I tried Noesis but didnt work
sample files link removed =.=" rules not allow
if someone want to examine the files pm me i'll give the linkss
.d2s is texture file ( u can view it by XnViewer or change file type to .dds, its like .dds file )
.skin is mesh file
.bon is bone file
.ani is animation file
