i heard that some DS phats had a special firmware that lets you change the brightness or something, and if you pulled a cartridge out while in picto chat and got a pink screen that was a special firmware. now i have several DS Phats, (for electronics projects), and every single one gave a different result after doing the pictochat trick. one gave a blue screen one gave a yellow screen one gave a green screen one just froze im not sure what any of that means. are they all different firmwares? also, whats the deal with Flashme? can i install it from regular slot-1 cart?
