Press [backspace] and CJ will pick up his phone and wire money to a corrupt government contact who will remove your wanted level. You must have a wanted level of 2 or more before the call can be made & the call costs exactly $1000. On some missions that have scripted wanted level increases such as the mission Driveby your wanted level will jump back up so avoid using it in those cases unless you wish to waste your money.
UPDATE: Version 1.1 has been made, they now include fxt. It comes in two flavors you can choose. 1.1a has full subtitled dialog, 1.1b has a simple bubble that pops up telling you the G-Man has received the cash which is a better option if you feel subtitled text with no audio ruins things.
To install you must have CLEO 3 or above, place CS file in CLEO folder & .fxt file in CLEO_TEXT folder located in the CLEO folder (create it if it is not there).
