Cheat Method:
Open Preferences.dat in Config subdirectory with a text editor and go to line:
int& N_LIVES =Int(); // is 3
-> change 3 to 99 (for example) = 99 lives
Line becomes:
int& N_LIVES =Int(); // is 99
Same for others params, go at line and edit:
bool& AI_TAKE_ME_OVER =Bool(); // is no
-> change no to yes = autoplay by cpu (in story mode)
bool& ENABLE_AI =Bool(); // is yes
-> change yes to no = disable others cpu players
const bool& ALLOW_LEVEL_SKIP =Bool(); // is
FULLY_PROPER_BUILD no yes
-> change to yes (erase "FULLY_PROPER_BUILD no").
You can now in game hit F8 to skip level and go to next one.
