I believe these leaks will only make people buy more Nintendo games as these codes will reveal many secrets, which one cannot find otherwise!
Some of the beta stuff my yield something of interest, especially if levels were cut for time or something rather than cut because they did not work.
Most of the source code to SNES and GB games likely has all the data already known (between cheats, level hackers, music extractors and any translation efforts you have most of the interesting addresses already, even more so if the game franchises are popular with hackers) and it is not like SNES/GB era source code is going to be much other than a bunch of assembly.
After searching a while i found the original gigaleak download link on /v/. I'm interested on the Diamond & Pearl prototype, but i don't know how to compile NDS games from source. Is there anything new there? tcrf page still isn't updated.
If it is a commercial game it gets harder. You will want the official SDK of suitable vintage (or maybe a later one and be prepared to do the work to bring the code up to spec) as none of the homebrew ones are likely in any kind of condition to take a run at compiling a commercial game.
The only one I am aware of that has been publicly released is really really really old. Most other public leaks are of smaller parts (the people playing 3d hacker have some, there is some stuff fished out of ROMs over the years and a few other random tools, apparently a later version of the emulator as well with this). Most of the bigger libraries (mobiclip/act imagine being one such thing) had phone home to authorise that I am not sure has been cracked. Privately held are some later versions (including into the DSi era, which you might well want here) but I don't think they ever saw a public release, never mind a cracked one.
Similarly most of the tools to interface other tools for say 3d, audio and the like will require what are now incredibly old versions of such things (they were hard to come by towards the end of the DS lifetime, and I can only imagine it is worse now as nobody really wants old tools like that).
Basically I think Nintendo learned from Microsoft's leaks for the original xbox and their own devs going out and buying flash carts to supplement things on older devices and locked things down somewhat.
I don't know what the code looks like here but if it is anything like the code we saw before from other things then likely precompiled/premade headers are things being used, in addition to a few custom tweaks to things. This means you get to replicate those (or maybe fish them out of the final deal) if you are going to try to adapt a homebrew thing to it.
Look at the code if you want to take the legal position (it might well trouble you if you want to contribute to pokemon hacking tools/projects and maybe some emulators in the future) and use that to direct another hack -- the trouble with assembly hacking is you never know if some random bit of code will reference something else randomly in the future but if you have the code you can be reasonably sure of that (don't know if they will have done any fun obfuscation) and also spare yourself a lot of research in general.
