Als je wat meer actie win in je Slave Zero demo, dan moet je onderstaande truc uitvoeren. Je kan dan level 9a en 9b spelen.1. Open the file "slavezero.ini" which is in the folder where the Slave Zero demo is installed. 2. Change the line m02_a = pimpscreen to read m02_a = m09_a 3. Save the file and run the game. NOTE: This does not work on EASY mode. 4. After you complete mission 1 the game will automatically load mission 9. You will then get a chance to play level 9a and 9b.
