Well then you don't have it set up right.

Just do not play any ds games and you will be golden.

So you can keep accessing the exploit without a DS flashcart? That's kind of cool. And if you want to play DS games, how much of a hassle is it to reinstall the exploit?
Get the flash card again to install the rop.
I havent installed a rop before so.. can I use the same SD card to play DS roms and execute the rop? Can they exist and function on the same SD card?

Does anyone know if this can be completed without a Gateway or any similar flashcart?
I've only got a 4.4 3DS and would like to know if I could do this, or even back up my sysNand for that matter
you can use the Gateway Launcher to Dump NAND and format the SD card for EmuNAND. All you'd have to do after is use EmuNAND Tool to inject your NAND into the SD (add 0x200 block of 0x00 before file), and use the CFW to use the DevMenu.

All the tutorials claim I need a flashcart. I don't have one of these.
Then there is nothing you can do.

I even tried to convert Pokemon Ruby and Sapphire Demo but when i start it says that i need to turn off the console.
Try this, and let me know if it works.

I tried but it doesn't work.I tired with SuperSmashBros and Pokemon Ruby Demo. I'm on CFW, I'm not using Gateway. Pokemon Art Academy is working only with Gateway?
I've updated my guide and those games work properly now.
but not if you're on CFW.
CFW cannot play games built on later SDKs (usually games from FW 7 onwards)

I hope that in the near future it will be possible to play 7.X games without Gateway.
