How to delete the last moves in a db?

Hello,

is there a way to delete the last move of each game in a database (chessbase, DOS command or whatever).

Lets say this is the pgn-database (just an example):

...and I would like to delete the last (mate) moves.

My idea is, I want to practice blindfold chess. So I could try to play the game through my mind and try to find out the mate move.

Any suggestions...?

You can of course manually edit the pgn with any text editor, to delete the last move.
