Note: This procedure involves editing a game file; create a backup copy of
the file before proceeding. Use a text editor to edit the "level.ini" file
in the "\data\levels\barcelon\script\" folder in the game folder. Change
the "NbMaxMotos=12" line to "NbMaxMotos=1". Change the "GainSR_0_0_0=10"
to "GainSR_0_0_0=100".
This will allow you to be the only racer and always win, with more
credits.
