calling pokemon masters! please help!

hey im trying to create a pokemon fan game and i have like a few questions lol.
ok so first what i really need help on is the algorithms of the pokemon games for gba.
like mostly battle system and stats and attacks.
like how the stats affect things such as damage, accuracy, speed, etc.

so first in an attack, if a move is 100 accuracy then will it ever miss? how does the stats of the pokemon using the attack and
the enemy affect if the attack is going to miss. what stats alter the accuracy?

second, what stats change the damaage of a move say with a power of 40? does the attack do 40?

i have a bunch of questions and thats all for now.
thanks for any help.
im a big fan of the games however i dont actually think about this stuff. so someone please guide me through it.

Go to Bulbapedia. There is a ton of information there to help you with this endeavor.

Bulbapedia or Marrilland is a good palce to look.

Also, if the accuracy is 100. It's a 100% that it hits.
But moves like sand attack(decrease enemy accuracy) or double team( increase evasion) will decrease that chance.
Moves with no accuracy is probably a "never miss" move like "Swift".

Also, attacks gets a Stab bonus if the move is the same type as the user. So it does a certain amount more damage than for others. (like a pikachu with thunderbolt vs a chansey with thunderbolt).

But I have no idea about how the damage is calcualted.
But I know that pre D/P/P(diamond, pearl, platinum) some types were Special Attack and some types were Attack.
D/P/P changed that (that's why Marriland is a good place to look).
So water gun or something is a SP attack.
The game checks Squirtle's SP attack and the attacks base damage and the enemy SP Def. Then things happen and damage is taken.

I know that There was some POkémon starter kit for XP somewhere though. It had everything in it already I believe.
