DS Flash Equipment > run homebrew without flashcard

#41451 - chrissieboy - Thu Apr 28, 2005 5:59 pm

Hi,

i saw on http://users.belgacom.net/bn967347/
that you can run polarium demo without a gba flash card.

How can i modify my homebrew so that i can direct upload it to the nds memory?

Or can't it?

Thanx you for help!!!

If you send your demo to nintendo and they sign it with the encrypted RSA signature, then you can upload it without a GBA flash cart. But that doesn't seem very likely, so at this point, you can't.

#41457 - chrissieboy - Thu Apr 28, 2005 6:47 pm

so only small commercial demo's/ games could be run??

#41459 - chrissieboy - Thu Apr 28, 2005 7:04 pm

sorry another question, but is it possible to run small gameboy advance demos with wifime? or does that also require a rsa ?

Er, no, that one is just plain impossible.

Running GBA .mb files on a Nintendo DS through Wi-Fi is probably impossible, but we might be able to run DS demos if we find a DS Download Play game that loads code and assets in two separate passes and is vulnerable to buffer overflow. Then we could send, say, SM64DS's signed DS Download Play bootloader and then overflow the slave with unsigned code posing as an oversize asset. Has anybody disassembled the SM64DS bootloader to see if it has any such vulns with which a standalone version of WifiMe could "interoperate"?

You could also patch the Nintendo DS firmware so that it will no longer check the signature. IMHO this will be the only/easiest way to multiboot homebrew. Only downside is that you will need to patch your DS first using passme/wifime and gba flash cart.

This patch isn't already in the new just released firmware?

You could maybe borrow a Flash card, and WifiMe shouldn't be a problem since you would already have a compatible Wifi Card.
Otherwise there would be no sense in patching for wireless boot if you have no equipment to boot at all.

Nope. It might be in the future though, depending on how badly ppl want it:)

Check out the new (crappy) video on http://users.belgacom.net/bn967347/

Yes, please.

THIS IS TOO COOL!! Just orderd a 256megabit extremeflashadvance...
But you still need a flash card to flash your firmware so it will be usefull too!

When planned to release the new firmware?

Hmmm, it won't save the time (cart writing is probably quicker).

But it would be nice, since I hate continuously pulling the cart out, writing to cart, putting it back in! Physical stress ;) !!

Of course, all this would be solved if the EFA people would make a version of the card that works even when plugged into a GBA or Nintendo DS system that has been powered off.

You kids and your new high tech gadgets!! I'm forced to rely on my Flash Advance Xtreme :P

I WANT! I WANT! Who cares about the time it takes to download, you have to keep in mind that this will save new devers $100 on a GBA Flash Cart! And from the video, it even looks faster. you have to compare the time of cart writing and swapping as well.

As long as they know someone who has a flashcart for the first FlashME apply.

Oh crap.. That's true.. I still want it though. :D

Why not organise some 'meetings' where people with a notebook + wireless pcmcia card + gba flash cart to come along and flash other people's DSs. Or charge $5 for a flash, or a beer for each flash. hehe I'm kidding do it for free you cheap skates! Actually a beer would be nice ;)
