Well, I was experimenting with emerald, load it onto NOR Flash tried it out for a few minutes, saved the game and shut the unit off. Turning it back on with BOTH the GnM AND 3in1 in the DS Lite results in the Datel startup screen then two white screens. Starting with ONLY the 3in1 in results in it being seen as a GBA cart, loads up save fine. Starting with ONLY GnM goes straight to it's little launcher thing as normal. Starting with only GnM then running v1.9c of Rudolph's tool get's you a no cart found, sticking in the 3in1 then pressing A resets the DS Lite. Starting with ONLY GnM then inserting 3in1 results in reboot. Moral, I guess that 1024Mbit FLASH plus GnM == BAD news.
