UPDATE: INDEED, The US GAMES WORK, BUT YOU HAVE TO PATCH IT DIFFERENTLY, ONCE PATCHED JUST FOLLOW THE INSTRUCTIONS AS IF THEY WHERE THE JP VERSIONS.

OK, for the past two days people been struggling for making Pokemon White/Back functional on their R4 SDHC.
Today, with a special thanks to Aurionfox, and anyone else who contribited to this finding, i will be posting this tutorial with the means of helping those who haven't had any luck booting eather Pokemon White/Black on their R4 SDHC.

First of all *links to ROMS are not allowed* so don't ask.

Things you will need
1.- Pokemon Black/White rom. (Don't ask, Google is your friend).
2.- Rudolph patch for the freezes.
3.- Lunar Ips for Exp fix.
4.- Desmume emulator.
5.- PC and R4SDHC.
6.- Official kernel 1.34
7.- microSD (2g recommended) (Anything greater than 2g gave me problems, feel free to try)

First this works with a R4SDHC, but if you have another one feel free to try it. (R4SDHC Only tested)

Download bellow (it has everything you need)

1.- Get a clean pokemon white or black rom (Dont't ask)

2.- Extract the contents of Pokemon Fix R4SDHC and First use the *Patch Black Fix* or *Patch White Fix* this is for Freezes. (included on Download link)

Patch the version you want using the corresponding Patch.(In this case pokemon Black)

3.- Now use the IPS patcher for the Experience AP (Included on Download link)

Use the correct IPS patcher corresponding on your version (In this case Pokemon Black)

4.- Once patched start the games using Desmume emulator, Start the Patched rom you created and save before you get your PKMN, Once you save you can close the emulator.

5.- Copy everything that is on The *SD* folder to the root of your microSD.

6.- Copy your patched rom to your microSD.

7.- Start your DS

8.- Boot WAIO.NDS

9.- Press (B) and find then Boot woodr4dldi.nds

10.- Once that is finish, find your rom, press (Y) then (Y) again.

11.- Press ® and make sure Cheat In Game(AR) is off and Reset In Game Off, Then press (A) to save, then(A) again.

12.- Boot your rom, it should freeze with two white screens.

13.- Turn off your DS. Then ON again and boot WAIO.NDS then woodr4dldi.nds again.

14.- Find your rom again, press (Y) again, then (Y) again, but this time change your save type to 512kb. Then press (A) to save.

15.- Boot your rom, this time it will work. Play a little bit and then save. If you boot your rom again and try to load it will erase your save file. (a blue screen with letters will show). If that shows you did it right.

16.- Now Go on your PC and connect yor microSD and find your save and erase it.

17.- Now find your RAM folder in the emulator, it should have a *ROMNAME*.dsv

18.- Now copy *ROMNAME*.dsv to the same folder you have your room on your microSD and change the file extension from .dsv to .sav

If for some reason when you load the .sav file on your R4 SDHC and it gives you a black screen, try using R4 Save Converter.

Or try this save and see if it works for you. Created by Aurionfox.

19.- Now Boot WAIO.NDS, Then woodr4dldi.nds and find your rom.

20.- Press (Y) twice and change the save type from 512kb back to *unknown/auto* then press (A) to save.

And if that doesn't work try putting 64M instead of auto/uknown. Some people claimed it worked for them.

If you did it right, it should boot and you will be able to save, gain EXP and no freezes. Enjoy

R4-III Upgrade

*NOTE*Note to anyone finding their character frozen when loading their save: When loading your game you'll be asked a question, select the bottom answer and then the first one. This turns off the C-Gear, if it's on you'll be unable to move.
Example:
Press No, then yes.

*NOTE*
This is what am using it a R4 SDHC. Here are some images so you guys can see it.

EDIT
I got Bored of the games all ready they are to short after beating the elite4

[Aurionfox]

ok im back from the school so lets see

@donvsnaruto

only english please read the rules

@1Gamer

hahahahahahahaha sorry buddy wrong post

@ZXmega

for you and all too, you cannot create a new save from the begining in your flashcard i repeated this so many times, you need a new save from desmume after you create your character, for some reason (maybe an AP) we cannot do that from the begining

@Xenon++

Thx, i was looking back to your post of WAIO and see that but for some reason i cannot launch the game without waio and then r4dldi, but yes we cannot use the save data as wood, other important thing is the extension of the sav files, wood works only if you put .nds.sav but r4dldi works only with sav, i think thats another reason right?

@Smashmaster
@Grarl

just from www.r4sdhc.com many people have problems with that flashcards, we explain that on the tutorial so we cannot offer more support

Use this r4

Aurionfox, anyway, when i thought that this part was normal, i then included my desmume savefile, but, the same problem was waiting for me... when i selected my character (which was on the menu screen), the screens turned both black...

 

[Aurionfox]

@ZXMega

... when i selected my character (which was on the menu screen), the screens turned both black...

here is a picture of when you need to save, NOT BEFORE!!! (sorry its necesary) i take this photo a couple of minutes ago from my PC, the same emulator from here, the same save data i have posted long time ago here too, if you cannot save then set save type to 64 mb, a bit too crazy but it works for some people

 

[davidjw]

i won't get the white screen but it keeps on the loading screen when i start the game?

 

[Aurionfox]

i won't get the white screen but it keeps on the loading screen when i start the game?

did you turn off the cheats and reset settings?

@MaK11-12

Sorry i was looking that right now, its the 4 option under the config menu then just open and change this option

 

[Nakazora]

Hi, sorry to bother.
I'm having a little problem with the step 15
I can't name the character! I choose the boy or the girl, then, when the game asks my name, it freezes!
The screen don't go to the naming part, then I can't play the game...

Anyone can help me?

P.S.: Before anyone asks, my screen doesn't turn black, it stays freezed, with the music playing, just before it turns black to name the char...

I'm doing something wrong? I tried to copy the save filke from the demume but the game don't show the continue...

 

[Aurionfox]

@Nakazora

Flashcard or emulator?, did you patch the rom?

 

[Nakazora]

@AurionFox

Flashcard, and Yes, I patched the rom...

 

[donvsnaruto]

Look at the pokemon When it arrives at the Black tenque That this picks up the save with a file called Direct Action replay something not and still does not start the Save screen is white, But Also Can I play at R4SDHC With exp and all that I When I got saved back Was not getting the save .. Look at the pokemon when it comes to Black tenque it takes to save to a file called Direct Action replay something and not yet started the Save is white, but I can also play in R4SDHC With exp and all that I saved when I arrived was not starting to save ..
Use this Use this r4 r4

 

[Aurionfox]

@Nakazora

ok same thing as ZXMega, you cannot create a new game from your flashcard, why you dont try my save games? to see if you can load the game

@donvsnaruto

second time they are going to ban you if you continue, only english please

 

[Nakazora]

@AurionFox

I tried it already, but the game seems to don't recognize the save file, it shows only the newgame option, and not the continue one...

I really don't now what's happening

 

[Sirithfalas]

There's any chance to have a working ROM on 1.4 r4i soon ? :/

 

[Aurionfox]

@Nakazora

Maybe its more common, did you put the same files (rom and sav) on the same folder with the same name?, also the sav needs a .sav extension not .dsv (remember sometimes you cannot see the extensions so you can put this name pokemon.sav.dsv and never see that problem)

@Sirithfalas

nope sorry chances are too low now

 

[Nakazora]

@AurionFox

I've already put the game and the save on the same folder, with the same name, and also have changed the extension of the save file to .sav, so it's not that.

 

[Aurionfox]

@Nakazora

ok let me think, you can try other possible solutions to this, try different roms, saves, firmwares, save type bigger than 512kb, this are the common solutions for the people who made it work, dont worry be patient just combine everything

 

[donvsnaruto]

Look at the pokemon When it arrives at the Black tenque That this picks up the save with a file called Direct Action replay something not and still does not start the Save screen is white, But Also Can I play at R4SDHC With exp and all that I When I got saved back Was not getting the save ..
