What should I do? ~~

umm...I want to know what should I do after I finished downloading Pokemon HG/SS, I mean to solve the problem(black screen?) when playing the game.. :(...for no$gba(I have to use it since my DS is broken... :'( :'()
step by step tutorial would be nice :D ~~Thank you ~~

I believe if you download the latest translated and fixed versions found here:
https://www.romulation.org/forum/index.php?topic=23083.0You should be able to play them on No$GBA 2.6a

umm...so i only need to download all the files in that thread? ???

No, choose whether you want to patch it yourself, or download the pre-patched ROMs, with 'Rudolph' so you shouldn't encounter any issues.
