There is one more requirement for the game to recognise the GBA and that is that both games need to be the same region so if you have North American Pearl you need a North American LeafGreen.

And for the boxes it doesn't matter which box you use as you are able to search through all of them for the pokemon "migrate".

I believe the name Zeromus most likely comes from Final Fantasy IV's last boss but I may be wrong.

I have managed to get the migrate option and pal park to work in 0.9.5 I think you need all the games to be same region for it to work though.

you need to extract the files from the archives which is a .7z file or .zip file etc. download a software such as WinRAR and open the 7z file to extract the .NDS file.

Yeah it's true the sprite is missing however bowsers mouth glows when he has eaten that special part so I just made sure i click again on the food that came around the time when he's mouth glowed and did it first time.

When you get to a battle where you have to turn the screen on its side one side of the screen will tend to stop or flicker you get it to work again briefly by closing the lid but then it just happens again and it usually happens on the screen you need at that moment in time.

I've encountered this too I just "close the lid" and open it back up and it works for a couple of seconds but it does allow you to read the text boxes so you don't miss the story.

I've been trying Heart Gold and I have managed to get to the second gym without any problems.
Can't wait for English release.

I think he meant this:
