My ROM Game won't start (DS Emulation)

Hi Everyone,

I hope your all doing well.

Lately i have tried to download the pokemon game '' Soul silver or Heart gold''.

I have done this via : emuparadise.me , here i have followed the instructions as clearly as possible.

1. Went to the emulator section
2. Chose the '' Super nintendo entertainment system''
3. Chose windows
4. And chose the followign out of the list :
ZSNES[1.51]
Download: zsnesw151-402.zip
Size: 847.45K
Version: 1.51
Homepage URL: http://www.zsnes.com/

after that i have downloaded the ROM :

Download Pokemon - SoulSilver Version (v10) (E) (59M)
(Nintendo DS Release #4840)

Followed the instructions again and opend them with WINRAR. When i launch the WINRAR system it opens up and the screen comes up (Blue systems with the stars in the background, which you download via the emuparadise website).

Go to the folder, and then the game showed in the list. But when i press launch load, the game doens't load and does nothing, just goes back to the main screen. Can anyone help with me ? I tried to tell all the steps i did, so maybe someone sees my mistakes.

Also i have no knowledge of computers of systems so i don't see what i did wrong. XD :).

Thanks everyone.

That is a Nintendo DS game, you need this to run it,

It should be pretty straightforward to understand.
