In the interest of promoting homebrew development, I am releasing my ram dump tool. I hope that others will try to build off this tool and release the source just as I have.

I thought there was already Kane49's ram dump tool? Is this one faster or what's different about it?

Its open source.

Does anybody think they can give a tutorial on how to get a hello world running from scratch? I'm talking about getting from a helloworld.C to a launcher.dat. Any help will be appreciated.

sorry for late reply, maybe you are still interested.
I regrouped all the information from this thread explaining how to install dev environment and compile on a wiki.
I don't know if all is correct because I didn't test it yet as I miss time, I hope someone can test and report if anything is wrong so it can be fixed for use as reference to any new users wanting to build homebrew.

It's fine for the late reply, thanks a bunch!

Ooh, nice work Drenn

GameYob should perform quite well on the 3DS, given the added power. I wonder how possible '3D' graphics are in the case of the GameBoys, though.

The gameboy color does have a few layers... low-priority sprites appear below most things, normal sprites are on top of the background, and the background can have high-priority tiles appearing above all sprites. So maybe I could do something with sprites. But I'm not sure if I could make high-priority background tiles "pop out", because there'd be nothing behind them... honestly doing anything like this would probably make most games look plain weird =P

 

[Arisotura]

Same issues as with the SNES, then. High-priority tiles are the deal breaker.

Thanks a ton.

Also a note for the non SDHC users go into the sdmmc. and comment out the 3 lines with if(!sdmmc_sdhc). Additionally you need an empty ram.bin on the sd card before running it.

A few questions regarding 3DS'S AES.

As for AES-128, according to: http://en.wikipedia.org/wiki/Advanced_Encryption_Standard, there's an initial round, main rounds, and a final round. There are also 10 cycles. Is the initial round and/or final round part of this 10?

The AES also requires an expanded key, referenced here:
http://en.wikipedia.org/wiki/Rijndael_key_schedule is an operation in which you reference "the four-byte block before the new expanded key". What does this mean?

Does the 3DS use the normal AES, or a variation?

If it's a variation, could someone explain the variations?

 

[Arisotura]

The 3DS uses regular AES.

The trick is that you don't directly give it a key to encrypt or decrypt the data. Instead, the AES hardware takes two keys from different sources (in the case of a NCCH, one key comes from the NCCH data and the other key is a shared secret). The two keys are mixed together in an unknown way. The resulting key is then used to encrypt or decrypt.

There is also no known way to get the final key out of the hardware. Without some hardware bug, trying to guess the final key would be equivalent to trying to crack AES without knowing the key.

i was going to make a new thread but instead since this is the homebrew dev page and new threads for something minor are frowned upon.. i was wondering if theres any homebrew developement of any sega related consoles? such as gamegear/mastersystem and or sega genesis it would be cool to have some sonic on the go =P i already have my true wishes thanks to staplebutter with a snes on the go =p apart from a few games that need the sfx chip integration but alas some of my childhood favorites in my pocket most emulated almost perfectly without sound is awesome so can we get some sega love too =P??

Last I heard you could repackage the gamegear VC with other games. But I think that's as close as we've got.

i didnt hear about that...did normmatt release his tool?

No it's all manual work. But all the tools are there and it's not too difficult.
