I finally got firmware.nds to load after I got a TTDS.nds Menu to load on my flashcard.

Anyways, I made a basic edit to a Mario VS Luigi level ( added 1 block ) just to test if it would work ( with r359 ).
On my DSi , I load up TTDS.nds and from there load firmware.nds then on my 3DS load up the ROM. The game stops loading a couple of seconds during the downloading process ( when Peach is throwing mushrooms and goombas at Mario ).

Why isn't this working? I thought firmware.nds was supposed to make Download Play work?

Using firmware.nds , Download Play with an unedited ROM works fine.
 Dirbaio made a mistake when making that tutorial so the tutorial won't work at all.
Thanks for the help but i'm still looking for a way to get Download Play to work.
Has anyone had ANY luck getting DP to work?

When does it exactly freeze?
When both DS's are at the "mushroom throwing" screen?

In that case maybe there's something wrong with your NARCs? Too big maybe? Did you edit tilesets or something?

Yeah both DS's make it to the "mushroom throwing" screen, but after a couple of seconds, the DS downloading freezes on that screen and the one with the ROM gets the screen "Communication Error, Press A to return to Title Screen"

And no, I just added a power-up block to test it before I made big changes.

hmm then I have no idea what's wrong.

Can you post an xdelta patch so I can test?
Also you could try to patch the ROM with the ASM patch template so you get the debug screen. If you do, take a pic and post it

I'll try upload an XDelta patch soon. Could you tell me how to make an XDelta patch or link me a tutorial?

there's a tool out there called XDelta UI that can do it.

To create an Xdelta patch is really simple.

-Open XdeltaUI. (be sure that the other .exe is at the SAME location of the xdeltaUI.exe)
-Go to "Create Patch" tab.
-On the "original file" section, click on open and select a CLEAN NSMB rom (modified roms will work too, but only to that specific rom)
-In the "modified file" section, click on open and select your modified rom. (be sure that is the same region as the clean rom you're using)
-Then click on the "..." patch destination button and chose a name and a directory to save the patch.
-Then click on "patch" at the bottom.

Now, the patch is done

Click this to download the XDelta file.

EDIT: Yeah, I fixed that in the last post, link is there now.

Sorry for the double post but I really need the help.

Firmware.nds won't work.
I have even tried Download Play with a DS Lite so don't think it is any new anti-piracy thing on the 3DS.
R116 won't work.
What revision should I use to get it to work, or is it possible to change the editor so it doesn't update the header for extra flashcard compatibility, so Download Play would work?

Thanks.
