so, to make it boot you have to change the memory addresses? I guess the only way then to make it work is manually rewrite the ARM7 ASM to use these new addresses cause if you open this up in IDA the functions are yet again only 14 and its just as broken.
any progress on the sdhc r4?Yeah that must be it. The arm7 code entry and arm7 ram entry addresses must be changed. If I leave them as is, it will cause an error has occured message. I don't do ASM, so rewriting the asm is definitely not something I can do.
Ok cool. Try the WoodR4 Launcher on the first post. The one marked under the greed "Confirmed Working" section.
Perhaps rather then trying to rewrite the entire arm7 binary, perhaps some kind of "payload" could be created that reads the arm7 binary, moves it to the correct memory address then jumps to it. That way arm7 binary is in the memory space it was programmed to use. It would help get a LOT of stuff to work too like other flashcarts since this will get around the initial block of TWL_FIRM not allowing the original arm7 memory settings at launch.
Alright so the area the ARM7 code normally lies in is the Shared IWRAM which I guess the 3ds wont directly load data in, the area you change it to is the Main Memory (as described on this page). I suppose I could write a little stub which moves the code back into that IWRAM and then jumps to it, though I am no ARM7 expert so it probably will take me a little.
Does your flashcart not work? It's called R4i SDHC 3DS

Then all you need is the patched TWL FIRM from that one site that cannot be named and your flashcart should work again.Yes, it's an R4i SDHC 3DS
It worked on the 3DS when it was just released ^^
And it still works on my DS lite, so I know the problem isn't the (old) flashcard
? Yes it's safe. This launcher isn't meant for carts like yours, it's for flashcarts that never worked on the 3DS (or DSi for that matter).
