I've made a tweak to x360ce2vigem in order to auto-calibrate game controllers upon connecting. In case anyone has any use for it here's the code:
int LXOffset[] = { 0,0,0,0 };
int LYOffset[] = { 0,0,0,0 };
int RXOffset[] = { 0,0,0,0 };
int RYOffset[] = { 0,0,0,0 };
bool calibrated[] = { false,false,false,false };
printf("Starting translation, close window to exit...\n");
while (true)
{
auto begin = high_resolution_clock::now();
for (int i = 0; i < XUSER_MAX_COUNT; i++)
{
ZeroMemory(&state, sizeof(XINPUT_STATE));
// The Mayflash WiiUPro adapter assigns the first connected controller to bus 4, the second to bus 0 etc.. This is to sort them properly.
if (i == 0) result = XInputGetState(3, &state);
if (i == 1) result = XInputGetState(0, &state);
if (i == 2) result = XInputGetState(1, &state);
if (i == 3) result = XInputGetState(2, &state);
