我去到Pokemon Diamond/Pearl 既 Pal Park 個阿叔吾俾我入。。。

Pokemon Diamond/Pearl 要升圖鑑,
LeafGreen一定要正版,
兩者應該要同一語言

你入不到公園門口還是公園內的人不讓你入?

入不到門口就要先升級圖鑑

入面的人不給你入就是你仍沒有連動
(插入卡帶後,開遊戲選單時多了一個選項,
入去再選6隻GBA電腦內的精靈,
確定後才成功,
之後再找那人)

P.S.選項不對就不能入

如果兩餅帶都是同一樣文字，要打敗五天王一次，在進入遊戲時按第三個，就會看到你在GBA帶的電腦裏的寵物小精靈，並選擇六隻到NDS帶，在Pal Park 個人，就會給你六個必捉球去捉六隻GBA帶的電腦裏的寵物小精靈。

你餅LeafGreen不可以是Eng，因為你玩的係Japanese 的Pokemon Diamond/Pearl
*如果你玩的係English 的Pokemon Diamond/Pearl，就係因為你冇在Pokemon Diamond/Pearl的主菜單按最下底的方格，選擇捕捉的pokemon（事實上無論咩版本都要做這步驟．．．）
你玩玩下就明白

Well... have you get the national dex?
You can get the national dex by encountered (caught, seen, or fought) all 150 pokemon (excluding Manaphy) in the Sinnoh dex. If you have fought everyone you have met (and hatched the Riolu egg Riliy (the man in iron mountain) gave you), you should have meet all of them after you fought E4.
After that, go to see Rowan. Oak will come into the lab and give you the national dex. Now you can go to pal park. You will see Oak again there. He will give you the pokerader. Using it in grass areas without a bike. Some grass will shake. Go to that pile of grass then you will meet a pokemon. Some of the pokemon are only available in this way. It MAY also increase the chance of meeting a shiny pokemon (pokemon with different color with the majority of the specie).
