Allow Feebas to be caught on any Valid Fishing Spot in Route 119 rather than only Three

In Wild_encounter.c, add the below lines CheckFeebas function. You can remove feebasCatchAllTiles and set set the function to always be true. I just wanted to show how a variable or flag can be there to turn this feature off.

static bool8 CheckFeebas(void)
{
    u8 i;
    u16 feebasSpots[NUM_FEEBAS_SPOTS];
    s16 x, y;
    u8 route119Section = 0;
    u16 spotId;
+   bool8 feebasCatchAllTiles = TRUE;

    if (gSaveBlock1Ptr->location.mapGroup == MAP_GROUP(ROUTE119)
     && gSaveBlock1Ptr->location.mapNum == MAP_NUM(ROUTE119))
    {
+       if(feebasCatchAllTiles){
+           if(Random() % 100 > 49)
+               return TRUE;
+           else
+               return FALSE;
+       }
        GetXYCoordsOneStepInFrontOfPlayer(&x, &y);
        x -= MAP_OFFSET;
        y -= MAP_OFFSET;

        // Get which third of the map the player is in
        if (y >= sRoute119WaterTileData[3 * 0 + 0] && y <= sRoute119WaterTileData[3 * 0 + 1])
            route119Section = 0;
        if (y >= sRoute119WaterTileData[3 * 1 + 0] && y <= sRoute119WaterTileData[3 * 1 + 1])
            route119Section = 1;
        if (y >= sRoute119WaterTileData[3 * 2 + 0] && y <= sRoute119WaterTileData[3 * 2 + 1])
            route119Section = 2;

        // 50% chance of encountering Feebas (assuming this is a Feebas spot)
        if (Random() % 100 > 49)
            return FALSE;

        FeebasSeedRng(gSaveBlock1Ptr->dewfordTrends[0].rand);

        // Assign each Feebas spot to a random fishing spot.
        // Randomness is fixed depending on the seed above.
        for (i = 0; i != NUM_FEEBAS_SPOTS;)
        {
            feebasSpots[i] = FeebasRandom() % NUM_FISHING_SPOTS;
            if (feebasSpots[i] == 0)
                feebasSpots[i] = NUM_FISHING_SPOTS;

            // < 1 below is a pointless check, it will never be TRUE.
            // >= 4 to skip fishing spots 1-3, because these are inaccessible
            // spots at the top of the map, at (9,7), (7,13), and (15,16).
            // The first accessible fishing spot is spot 4 at (18,18).
            if (feebasSpots[i] < 1 || feebasSpots[i] >= 4)
                i++;
        }

        // Check which fishing spot the player is at, and see if
        // it matches any of the Feebas spots.
        spotId = GetFeebasFishingSpotId(x, y, route119Section);
        for (i = 0; i < NUM_FEEBAS_SPOTS; i++)
        {
            if (spotId == feebasSpots[i])
                return TRUE;
        }
    }
    return FALSE;
}
