Please advise a good working converter BSP to MAP

[Kriskopreved]

Searched all over the internet ,but could not find a working converter .... Or am I doing something wrong ...

If not a little difficult to write instructions on how to properly convert from BSP to MAP

[mrwonko]

A BSP can't be losslessly converted back to .map. The only way in which a BSP can currently be changed without losing information is changing the entities.
