Dies, died, will die.
I've just located the lookup table generated by the Mersenne Twister RNG. It starts at 022151D4 and ends at 02215B90 (in White).
The very first 32-bit value in that table is the seed used to generate IVs. Plug that seed into RNG Reporter's Researcher feature, set it to right-shift the result 27 bits, and the next six values are the IVs of the next Pokemon you catch.
Once I figure out a way to advance this RNG, we can catch flawless and\or shiny Pokemon that pass Wi-Fi and VGC hack checks - on an emulator. (Not sure about breeding yet, but it should be a lot easier.)
The big challenge is still figuring out how the initial seeds are generated. Without that info, it won't be possible to manipulate the RNG on a cartridge.
Turning the C-Gear on and immediately off seems to advance it by 1.
e: Maybe not. Having a bit of a hard time figuring out exactly how much the advancement is.
