I can't read/write/speak Chinese, but I managed to navigate their site without too much trouble, just lucky I guess
as for knowing they were Armadillo files, I recognised the tell tale TMP files that get dumped in the TEMP folder or the folder you execute the file from! Plus, if you take a HEX editor to the files you can find the text 'ArmServerInfo' which is a giveaway!
As for the 'rakey', it must be wrapped with a newer (or extremely old) version of Armadillo, unfortunately no 'unwrapper' is available, so solly
