+## Remove Warp Fadescreen
+
+credits to ghoulslash
+
+There might come a day where you want to fade the screen to black in a script and play a fanfare, print a message, or do something else, and immediately warp. If you try this in vanilla emerald, the screen will fade FROM black, and then back TO black. Instead, let's create a flag that removes the fadescreen part of the warp script commands and we can do something like this:
+
+
+### 1. Define a flag
+
+Add or replace a flag with `FLAG_REMOVE_WARP_FADE` in `include/constants/flags.h`
+
+### 2. Give the flag a purpose
+
+1) Find `WarpFadeOutScreen` in [field_screen_effect.c](../blob/master/src/field_screen_effect.c#L102) and replace the entire function with:
+
+
+```c
+void WarpFadeOutScreen(void)
+{
+    u8 currentMapType = GetCurrentMapType();
+    if (!FlagGet(FLAG_REMOVE_WARP_FADE)) // fadescreen if flag not set
+    {
+        switch (GetMapPairFadeToType(currentMapType, GetDestinationWarpMapHeader()->mapType))
+        {
+        case 0:
+            FadeScreen(FADE_TO_BLACK, 0);
+            break;
+        case 1:
+            FadeScreen(FADE_TO_WHITE, 0);
+        }
+    }
+    else
+    {
+        FlagClear(FLAG_REMOVE_WARP_FADE);  // reset flag internally
+    }
+}
+```
