The link you posted confirms exactly what I said in my first post.  Those are pictures of a hack to connect an SD reader directly to the DS port.  Nothing more.  It's not a miniSD flash solution for DS.

The author shares a number of experiments he has tried with the DS . . .

1) a compact passme device with a built in DS game rom (does nothing more than a regular passme, it's just smaller in size)

2) a clever hack to connect a miniSD reader directly to the DS game port using passme serial (this could be used as alternative SD storage, but not as a supercard replacement)

3) several experiments using the GBA port of the DS(non-working)

Like I said before . . . A real DS flash solution will probably stick out of the back like superpass2.

Considering that the ds its-self can play a 50 some meg game off of a ds cart that is a ROM chip.... Why not?  A firmware re-write to access the fat file system on the sd card,  or instead just plant raw write a small boot  application (similar to the supercard boot screen) onto the first sectors of the sd card. the supercard was first made to play gba games. thats why it has the 256Mb memory. Im sure similar operation could be mimic'd by the ds. The regular ds carts just read what they need when they need it. not the whole rom space. i'm sure that could work with just 4mb ram... with the proper wizardry....  BTW the ONLY writeable memory in an actual ds cart is either a 4K or 64K save chip....

The point is the pictures are not a miniSD supercard replacement.  Sure a 50MB game ROM is possible, because the DS already knows how to access a real game ROM.  The DS doesn't know how to access a miniSD.  Yes you could "re-write" the DS firmware to access the miniSD, but what are you going to use to modify the firmware in the first place?  You would still need a passme+supercard to update the DS firmware.

BTW the ONLY writeable memory in an actual ds cart is either a 4K or 64K save chip....

Geee wiz, really?  :lol:  I think we all understand that.

okay, so I stated the obvious.  But why should accessing the flash memory (EEPROM) be much different then the PROM in a ds cart? other than the file system data? If you could make a ds bootable image in the first sectors of the flash with the necessary code to access the rest of the card... why not? the only reason I can tell we can't do that yet it that nintendo's encryption is still not yet understood, so therefor it requires a firmware hack. Once that is circumvented, why would a sd card be any different then a gba flash cart, minus the battery that wouldn't be there for the save data?

Point is that it is a start. someone is actually playing with the idea... and something could come of it.

[EDIT]

After looking over the specs on the gbatek site... idea...  Using a cut down supercard (to fit ds lite cart slot correctly. read "doesn't stick out like a sore thumb") and mapping the memory functions to the ds slot with a ds to minisd adapter like pictured, may be able to at least make a system that works like the gbamp does with moonshell (i.e. you can take the media card out and put it back in without crashing, as long as you don't try to access the memory card while its out. This only works with the gbamp though, as far as I know.)  

Even with the extra hardware, it sounds like something I would like. plus I would hate to have to buy all new microsd cards for a similar system that wasn't put together like that. call me a neat freak but I hate how far the carts stick out on the ds lite!
