Wood R4 Help!!!

So, I followed instructions putting the right files in the right place but it still doesn't work.
Honestly I don't know what's wrong with what I'm doing. I use a R4i Gold (or R4i SDHC, is there any difference??)I wanna play 999 and Golden Sun so baddddd....=(Please help me.

Use Wood R4iDS Gold
If you have R4i DS Gold v2.0 it doesnt work!

I'm not too sure if its a v2.0 or not, how can I check?
