E' disponibile per il Grand Prix 4 di Geoff Crammond la nuova versione 3.60 dell'indispensabile utility GPxPatch, che apporta al gioco numerose features aggiuntive e novità ; ecco le particolarità introdotte da questa release:
#CONTINUE#
Added an extended pause mode. This means that when the game is paused you are able to do what you always wanted to do but were not able to. The option is turned off by default, in case it gives certain side effects (I didn't get any, but I didn't test it extensively). You can find the option on the main GPxPatch tab. Setting the option to indeterminate requires you to press Enter to active it when the game is paused.
