question about rigging

[sijaab]

hello, i am (re)ripping models from the dreamcast game illbleed,
i have ripped some enemies and bosses and reripped the playable characters with rigging and this is where the question comes in,
   
jorg S. baker in noesis
   
the same model in blender
as you can see the rig is quite weird (it seems to move properly), so what do i do now should keep the rig or delete it before i submit it 
btw: all the models have this
   
thanks for reading
