I know, I know, this is probably a very stupid question. But, consider the following. Imagine if there was a program for your computer that built a .cia file of a modded 3DS game. The moddded 3DS game in theory, would load a NDS game instead of the actual game itself. Like, think ARM9loaderhax for a 3DS game. Milliseconds into booting, some type of mod takes over the booting process to force the game to boot a Nintendo DS game. I don't know if that sounds insanely stupid towards a developer, but if this was in theory possible, think of the endless possibilities! I did try looking up what code is involved when a 3DS game boots up, but I couldn't find anything for the life of me. So this is just one of those "conspiracy theory" posts, I guess. The only idea I could think of this being possible, was, if some 3DS game was already possible of playing a NDS game. Is there any game thay can do this? Like, a game that has a NDS demo built within the game itself? (ala the style of SSB masterpieces) If some game had a NDS demo in it, maybe we could mod the game to automatically play the "demo" upon boot, but have it play an injected NDS rom. I don't know, this is only my idea of this somehow being possible. Are there any devolopers that could provide insight to the subject? This might be a rather interesting discussion. P.S.: Yes, I know about the current project of running NDS roms off the SD Cards natively. But, I've heard that it might not be to the same levels of a flashcart in terms of stability.
