Here is a level cheat for IWAR:

Open the IWAR directory on your hard drive. Inside there should be a folder
named "PSG". Open it. Inside of the PSG folder there is a folder named
"RESOURCE". Open this too. Inside of the "RESOURCE" folder there is a
folder named "SCRIPTS". Inside of "SCRIPTS" there should be a folder named
"PRECEDENCE". Inside of the "PRECEDENCE" folder there should be a file
named "PREC" which you should open with a spreadsheet program, like Excel,
and change all the numbers in the "PREC" column to 0, and save. Now you can
access all the levels of IWAR from the beginning.
