+In Generation 3, you normally can't catch Pokémon without getting the Pokédex first. Because of this, it assumes that if you catch a Pokémon, you **must** have the Pokédex, so it shows the entry.
+
+With this change, if you catch a Pokémon without having the Pokédex, it won't show their entry. It will still register them, for when you do get the Dex.
+
+Open [src/battle_script_commands.c](../blob/master/src/battle_script_commands.c). Find `Cmd_trysetcaughtmondexflags` and add the following `else if` in between the existing `if` and `else`:
+```c
+    else if (!FlagGet(FLAG_SYS_POKEDEX_GET))
+    {
+        HandleSetPokedexFlag(SpeciesToNationalPokedexNum(species), FLAG_SET_CAUGHT, personality);  
+        gBattlescriptCurrInstr = T1_READ_PTR(gBattlescriptCurrInstr + 1);
+    }
+```
+So in the end it ends up like this:
+
+```c
+static void Cmd_trysetcaughtmondexflags(void)
+{
+    u16 species = GetMonData(&gEnemyParty[gBattlerPartyIndexes[GetCatchingBattler()]], MON_DATA_SPECIES, NULL);
+    u32 personality = GetMonData(&gEnemyParty[gBattlerPartyIndexes[GetCatchingBattler()]], MON_DATA_PERSONALITY, NULL);
+
+    if (GetSetPokedexFlag(SpeciesToNationalPokedexNum(species), FLAG_GET_CAUGHT))
+    {
+        gBattlescriptCurrInstr = T1_READ_PTR(gBattlescriptCurrInstr + 1);
+    }
+    else if (!FlagGet(FLAG_SYS_POKEDEX_GET))
+    {
+        HandleSetPokedexFlag(SpeciesToNationalPokedexNum(species), FLAG_SET_CAUGHT, personality);  
+        gBattlescriptCurrInstr = T1_READ_PTR(gBattlescriptCurrInstr + 1);
+    }
+    else
+    {
+        HandleSetPokedexFlag(SpeciesToNationalPokedexNum(species), FLAG_SET_CAUGHT, personality);
+        gBattlescriptCurrInstr += 5;
+    }
+}
+```
