Help me!

I downloaded some roms archive RomUlation but not all of them work in my DS.
Why?

You have to tell us more if you want help. What games, what flashcart, and how do they not work?

Using a R4 with 2GB microSD, the games are as follows: -3538 - Grand Theft Auto - Chinatown Wars (E) (M5). Nds
-5256 - FIFA 11 (DSi Enhanced) (E) (M5). Nds
-5291 - Sims 3, The (DSi Enhanced) (E) (M6). Nds
-5305 - Monopoly (E) (M3). Nds
-5533 - Inazuma Eleven (IT). Nds
-5592 - Yu-Gi-Oh! 5D's World Championship 2011 - Over the Nexus (J). Nds
-5594 - Sports Collection (E). Nds These ROMs can not even load, the Consol goes directly to a blank screen, and you plant them.
I downloaded along with these other ROMs, type: -2911 - Guinness World Records - The Videogame (E) (M5). Nds
-0413 - Tetris DS (E) (M5). Nds
-4817 - 8Ball Allstars (E) (M5). Nds
-0336 - FIFA Street 2 (EU). Nds And they work great.

Ok, what firmware do you use on your R4?

I think "V 1.18" English version.
This is what I read in the string low to the Home page.

Ok, that is a very old firmware. You need to use Wood R4: http://filetrip.net/file.php?id=27380

OK I downloaded on my PC. And now?

Ok, open it with 7zip or WinRAR. Then, copy everything in the folder called WoodR4_v1.46 onto your MicroSD.

With FreudianLemur six great help, I have to do it later though, I have guests at the table and it's lunchtime.

Ok. I don't understand "six", but ok.

"You are" (bad translators!!).

Please post this in the correct thread next time.

@ FreudianLemur.Your help was decisive. Thank you for your time have you spent,
I hope to help you in the future.
