1) in the workarea dir you can find the save game files(es.hgame01-02 etc.)
If you have only 1 life you can edit the save game and change the 6th row for example one life is 0101 change to 0103.
2) for money -resources -and all you want you need to edit the ce_text.wad in the main directory there you will find all, for example i find the level resources for level 13 at line 0007f980 .
