what we're doing is Direct SD Loading
what a flashcard does is kinda.. well its a Image Loader for the Emulated Slot1 (atleast how i understand they work i know what we need to do vs how card actually work is vastly diffrent and Difficult)
Flashcard upon Rom Selction Loads Rom as an flatout .img/.iso of sorts, -> Slot1 emulation Begins -> Internally Data is streamed Live to the Emulated Slot 1's Nand Flash Storage with likely on-the-fly pacthing on all real Slot1 calls are directed at its emulated one so it doesnt try to read the actual Slot1 Stored info on the card (Kernel/Fake game header etc.)
in what my mind gathers our solution in being the "dirtiest Route" is in essence Emulate a flashcart. but the overhead probbly would leave it N3DS only likely. best b et to start poking where we should be looking at is a flashcart for the DSi/DSOrginal that was OpenSource if any/had leaked Source and examine its Slot 1 Emulation/Calls and go from there.
will we have Cheats + SD Rom access "Maybe" w/ the big priority being making SD Loading work but when this is done , again likely N3DS Only. with Rom Loading compatable w/ both and by that point we're better off using a flashcart IF you want cheats unless NitroHax is tied into it.
for my typos this post i apologize its almost 4am and i've been up all night streaming the second half of Minecraft Storymode since 6PM EST Yesterday (chapters 5~8)
@Apache Thunder care to correct me if im wrong or point me where on teh track i'm confused on about what obsticles we need to deal w/ How flashcarts do thier thing and where to look in making SD Loading work?
