Besides the hit television series there is a CSI video game.
To get the bonus material without have to complete the cases perfectly you just need to edit a file.
Find the "Saved Games" folder in the game directory and your saved games file. Make a back up of this file (in case things go hay-wire). Open the file in Notepad and place the below on one line at the very bottom:
[[#evd: 100, #hint: 0, #ranking: 3, #bonus: 10, #score: 100],
[#evd: 100, #hint: 0, #ranking: 3, #bonus: 10, #score: 100],
[#evd: 100, #hint: 0, #ranking: 3, #bonus: 10, #score: 100],
[#evd: 100, #hint: 0, #ranking: 3, #bonus: 10, #score: 100],
[#evd: 100, #hint: 0, #ranking: 3, #bonus: 10, #score: 100], [#bonus: 25]]
