    So it's my first post,but lets be quick.
    I've got a broken ds lite with a friend,where the top screen just keeps white,but the ds itself work propperly.
    I was searching for a screen swap code for mk and found it:
    5203809C E1D100B0
    0203809C E51FF004
    020380A0 02000000
    D0000000 00000000
    52000000 E7FFDEFF
    E2000000 00000034
    E92D5FFF E5910000
    E3800902 E59F3014
    E1530004 1A000000
    E3C00902 E5810000
    E8BD5FFF E59FF004
    022CC594 04000304
    020380A8 00000000
    D2000000 00000000
    (Made by cracker)
    But for some reason i can't get this code to work.Yes i'm using mkds europe version, but does this cheat only work with action replay it self of does it work with r4?
    I'm using r4 and all other codes work fine, yet it does not recognize mkds (eu) codes.
    My point is, is it possible to translate this code to the usa version?If not, what am I doing wrong?
    I would really like to test this lcd swap code!

    It's possible the code is for a different version of the ROM than what you have. Sometimes a ROM has multiple released versions and the codes may not work for all versions, even if they're all the same region.

    Are NDS game known for getting revisions unlike older classic games? IS not like it can get online updates. They would have to make a new cart and sell it as normal, hard to notice a different without definite sign of one, like Donkey Kong Country. :P

    Well, they don't often get revisions, but I do know there's at least a version 1.0 and 1.1 for NA copies of Mario Kart DS...so PAL probably has multiple revisions like that as well.

    Even if they did get revisions, no one ever advertised them as a update or anything, is sold as common as the normal carts so it would be hard to know which version you got unless you purposely test for difference. Just like Donkey Kong country and is various glitches between 1.0 1.1 and 1.2 or different regions that didn't get the specific version.

    Although from experience you are right as different codes do work for specific revisions of a game, just like people who list game genie codes for sonic 2 on genesis has 2 sets of codes for each revision.

    Usually a ROM will have the revision number in the filename if you download it from the right places, so...

    Well i did swap the rom and managed to make it work properly, but the problem is when trying ds download play.If i host the game(with the code) the second ds freezes at nintendo logo.I've seen in some other posts that ds download play has a check to see if the game received is not modified, wich made me belive that modifying the game with this code would fail in that check leading to the logo freeze.
    I didn't tested with other console hosting a normal game, and this rom with the code connecting, but i'm not very confident that it will work out as intended.
    Do you guys think i should try or just be happy that i can at least play with the broken screen?

    Are you sure about Mario Kart DS? All the current dumps seem to indicate there is only one version of this game. I can't seem to find any trace of a (Rev 1/v1.1) version, and No-Intro tend to be on the ball with this stuff:

    I was actually going to look into making a universal code like this that works for any game via button combo. This would make a lot of games playable on gameboy macro with being able to swap screens on the fly

    It's a bit long, but here is a code to swap screens on Mario Kart DS (US)
    You press start+select to swap screens, but dont press the buttons until the race starts (or a demo race is played) after the first race is loaded, it should be safe to swap screens any time
