It would be better to put it before the loop, when the buttons are pressed, you don't want to do anything else and just enter the menu, right?
Also add #ifdef to not break other things.

Something like

collect_events(state, NULL, NULL);

#ifdef <something from your platform>
if (state->keystate[5] == 0xC0) {
  result[0] = 2;
  return 0;
}
#endif

for (...

for (bit = 0; mask != 0; bit++, mask >>= 1) {
if ((mask & 1) == 0)
continue;
