Hello

 

i just want to mod a racing game for Android but which SUBs should i change to ADD? the function GetPremiumCurrencyPrice is getting the premium price for the car to buy.

 

i don't wanna compile the game and test it many times because my device is too slow to install and uninstall the game. i just need your help so i only have to install the game one time

GetPremiumCurrencyPrice(im::app::car::CarDescription *__hidden this, int)
