remapper_mask does not seem to work anymore

[phillowAT]

Hi,

i followed the instructions here: https://www.consoletuner.com/wiki/index.php?id=t2:remapper_mask but got the error: "Illegal operation 'remapper'".

#include <remapper.gph>

init {
    remapper_swap(BUTTON_15, BUTTON_16);
    remapper_swap(BUTTON_16, BUTTON_15);
    // Only to the controller on Input-A
    remapper_mask(RMP_USB_A);
}
