DS Flash Equipment > DSdev without GBA flash cart

#73465 - xproductions - Sat Feb 25, 2006 9:33 pm

I'm thinking of this:

is it possible to have both the passme2 sram binary (I have a new firmware DS) and flashme flasher on sram? Then one would use wifime/wmb to load homebrew. The flasher probably wouldn't be very hard to modify.

Actually, putting binaries in SRAM is very difficult. SRAM is designed for 8-bit reads, but when executing from Thumb mode, it reads 16 bits at a time. So instead of seeing 12 34 56 78 it sees 12 12 56 56. The only way to actually have working code in SRAM is if both bytes of each instruction really are the same, which of course is quite a task.

If you load the PassMe2 SRAM code into GBA SRAM and the most recent version of FlashMe into GBA ROM, you can flash your newer DS.

He said without a flash cart. I'm guessing he wants to use a commercial game's SRAM.

No, you can't load FlashMe entirely into the 32 KB SRAM of a commercial game. However, it may be possible to load at least the recovery code, so that you can continue FlashMe with the GBAMP, but nobody has done that yet.

I think I heard some games (the E-Reader being one) have 128KB. Still not enough, but closer. :-p

Silly me, it turns out I have a v3 DS (old firmware). I just bought it with no games, so I assumed it must be a new firmware one. Then I read about the magnet trick.

Magnet trick? The Pictochat trick is much easier, and requires nothing extra. (See my sig.)

What is the magnet trick?

enter pictochat and hover a magnet near the start+select buttons. it appears that the card-inserted sensor is sensitive to magnetic fields.

That's the sensor that checks if the lid is open or closed. It works based on the magnetic field of the right speaker.
