As someone who has researched the glitches of DP for a couple of years now, I decided to put together a TAS exploiting them to beat all bosses. Under Major bosses I count all Gym leaders, Galactic Bosses, Rival battles, the E4 and the Champion Cynthia.
The TAS would be played on Japanese, since the Japanese games have two notable exploits that make this route a lot shorter over the international releases. For those of you that are unfamiliar with DP's exploits, there is a way to get out of bounds known as the voidglitch which allows you to read RAM as Map Id's, and get to anywhere in the game. In this out of bounds section, it is possible to manipulate tiles as well, which the TAS will use to acquire a Tentacruel at level 54 right after the second gym. Right after, it will start exploiting TAS-exclusive Walk Through Walls glitches, Wrong Warps and sequence breaks. Some of this tech can be previewed below:

I have never tackled a 'big' TAS before, but I have made some smaller ones exploiting this tech, such as this short showcase of a TAS catching Arceus:
Arceus voidroute TAS
The routing process for this is still ongoing, and finding the optimal strats will be interesting to say the least. The main reason for this being that once we exploit one Wrong Warp, every Pokémon center in the game becomes a hub to get out of bounds from and Wrong Warp even more. Next to that, it's hard to decide when to simply unlock a city's fly location and fly to it later, or to abuse the Walk Through Walls skips, since voiding and save resetting could in some cases cost more time than it gains.
I think this could be very interesting, as the entire game becomes a playing field to abuse glitches, warping from place to place and show exploits that have never been shown before.
What are your thoughts, does this sound interesting to you?
Small note; all exploits relying on ASLR are bound to one specific Mac Address which is part of the generation process, so it would specifically work on 1 Ds.
