> If the supply of compatible flashcarts ever dries up, it will definitely get harder, though hopefully there will be more software exploits discovered by then.

another area of research is many flashcarts are actually obfuscation around FPGA and integrated flash perhaps if there was more interest a design could be produced in the spirit of open-hardware sans Nintendo property.

Hell, the original R4 managed it with 2006 hardware. It's conceivable you could do the same thing today with an RP2040.

EDIT: I found a recent GBATemp thread where some research into flashcart design is going on. Maybe something will come of that. Link: https://gbatemp.net/threads/gathering-ds-flashcard-knowledge...
