At a point I did some research about shenmo clients using the wayback machine thanks to @Psytrac.
I failed to download the stuff I wanted though.
From my experience shenmo clients that we are looking for have smdl_ in the name!
Code:
shenmo.wanmei.com/download
http://download301.wanmei.com/shenmo/smdl_ccb_20100318_0.2.0.exe
http://smdl.dl.wanmei.com/shenmo/client/smdl_ob_20110804_0.16.0.zip
http://smdl.dl.wanmei.com/shenmo/client/smdl_mg_20111125_0.19.0.zip
http://smdl.dl.wanmei.com/shenmo/client/smdl_mg_20120320_0.24.0.zip
http://smdl.dl.wanmei.com/shenmo/client/smdl_bfg_20120523_0.27.0.zip
Best case scenario is to find the earliest Shenmo client and to have all the patches Before 0.63.
Then with more trial and errors,we can figure out the versions through manual updates!
