I'm sorry to be more enduring, but...
Could you teach me how to activate the national dex in my hack?

Yay! You're welcome.

No prob.

Yeah, I think that script should be good. I think the problem is the variables you're using (0x4001 and 0x4002).

When I pick variables to use I always check here (http://www.pokemonhackersonline.com/showthread.php?t=14110-Flags-Vars-and-Script-Tiles (In the spoiler under "Vars")) to make sure that that variable isn't being used for something else in the ROM and editing it won't mess anything up. This post says that 0x4001 is a "temporary/disposable variable", so I think that means the game is writing stuff to 0x4001 constantly (and thus overwriting the value you set with your script).

So I think what you need to do is open config.h in notepad and change 0x4001 and maybe also 0x4002 to variables that aren't being used already. You should be able to use anything in between 0x4011-0x40FF that isn't already being used by a default FireRed script you want to keep intact. Again, you can check that link I pasted above to see what vars are used where.

Reinsert mega evolution after you've edited config.h. Then change your script to set the newly chosen vars instead of 0x4001 and 0x4002. I think it should work then.

Thanks man :)

Well, if you are good at scripting then you can easily do it...
.
if you had read the last line correctly

Wait on, I will have to check it :)

:3c Whoa!! Never expected that...
by the way I did nothing, but simply gave you advice :)

I will be waiting to play you hack :D

Cograts!!
by the way did my suggestion come handy???

I made item 0x34 the mega bracelet, i also placed an NPC outside my house to give it to me and i set the master ball to act as Charizardite to evolve Charizard into Venusaur (as a test) but i don't get the mega option.

Yes its the way... but tell me.. what is the item 0x34 in your game and
is you are referring as mega evolution not working, is that item in your bag???

I swear man you're beyond MVP

No prob!

Thanks for helping out, Learner!

Pen, if you go to your src folder and open config.h in Notepad, check what var is listed after "#define KEYSTONE_PLAYER_VAR". Then, use a script to set that var to the ID of item you want as your keystone. So, if you want to use a Lava Cookie as your keystone, have a script with setvar (your var) 0x26 (Lava Cookie's Item ID).

You can also change the default keystone in config.h by editing the item ID following "#define KEYSTONE_DEFAULT". I think you will still need a script setting your var to that item ID, but I'm not certain.

hello again i managed to create all the items but im not sure what i should repoint for the megakey to trigger the evolution instead of goldteeth.

Its my pleasure to help out!!!

I am still a learner for rom hacking but I feel happy when I can be of some help for someone :)

Nope. The only thing you will have to do is create the mega stones as general items.... and then in pokemon evolution goto mega evolution and in paramater select that stone for the pokemon you want to mega evolve...
That works :)

Adding mega stone and bracelete is just like adding any simple item into the rom...
