DS Misc > Wifime...2?

Hey all. I was ... reading some NFO's when I saw that there was a dump of the Ninja Media Launcher, which is only 1Mbit. Since the cart can boot stuff from the GBA slot as a NoPass, and is only 128KB, I decided to "back it up" and send it over WMB to see if it can boot my Supercard on an unflashed system.

Sadly enough, it didn't. It worked on my flashed DS, though. Why doesn't it work? Since it looks like it has a secure area(and appears to be "official"), and can be booted from DS slot, why can't it be sent over WMB?

Sorry if it's a little piraty for this forum, but it's not sponsored by Nintendo(and is even helping Nintendo loose money) so I though it would be okay?

DS Download Play needs a valid RSA signature, which commercial game carts don't have.

What you described has already been tried with other NoPass cards, unsuccessfully. DS Download Play and DS Game Card have completely separate security: DS Game Card uses a symmetric key (and was cracked when the keys were pulled out of the BIOS), but DS Download Play uses public/private keypair.

A successful WiFiMe2 project will start by completely documenting the protocol that one or more commercial games use for the second stage of their boot processes. And it appears that Mighty Max is finally getting around to doing this.

Hey, just a suggestion - but is it possible to write this to a passme1 or 2 - that way people could make their passmes fully firmware compatable

Thanks for explaining, all this time I thought the RSA on the DS carts and WMB apps were the same...

You mean turning a PassMe into a NoPass device, right?
I don't know anything about that stuff, but I guess it does go into the right slot. (Probably not much of a chance, though).

No, it is not possible. The 'NoPass' carts have a FPGA(or ASIC, not sure, but basically the same I guess) + FlashROM on them, the passme1/2 have only a simple CPLD. It just can't be done.
