"I thought I would make the first post about this here in this community before all of the hear-say begins about what it *IS* and what it *ISNT*, and if I forget to mention anything, please feel free to ask in this thread. :)
Basically, today started the first beta test of a new firmware for the DS, made by a member of the #dsdev comunity (loopy).
What CAN it do?
* Allows you to play home made demos that would normally require a PassMe or WifiMe without those devices, and loads the demos from GBA cart as normal.
What can it NOT do?
* Does NOT allow you to play commercial games from a GBA cart
What is required for the firmware update?
* An existing working PassMe or WifiMe to load the firmware update program. Once loaded, these devices are no longer required.
Will I have to remove the housing to the DS to apply the update at all?
* Only the battery cover. There is some stuff in there that has to be messed with (i'm not going to give out the specifics right now, as I dont want anyone messing up their DS units, because the LCD controller is also accessable in there)
Does it add any new features, such as Pictochat upgrades?
* NO! The only thing that has changed is to allow DS games to load from the GBA cart slot without the use of a PassMe or WifiMe. This is all that it does for now.
Is there any reason why I would want this new firmware?
* Only if you plan on making/playing home-brew demos, and have a GBA flash cart. Otherwise, it will be useless to you."
Correction: The firmware patch beta credits Loopy, Costis and Darkfader. Not Darkain.
Darkain happens know what's going on, and he and posted the above comments in the Nintend_DS LiveJournal community.
