There are FAQ's here,but briefly:
Use Neo-Max 1.9(you sound as if you have no problems with Slim loader-feel lucky,some do.)
Click"Format",Click"nds loader"(moonshell or not,does not matter,just make sure to support sd\mmc-just leave it alone,press ok,at format....)
Then click"add",and find where you have MK 2/3 Menu V0.6 BETA 2,click"single-ROM",and it should burn the menu to the flashcart.
Then-FORMAT your SD card(you are gonna have to do that a lot,also defrag it from time to time).
I have the best luck from there if I find whatever I am trying to send to the SD card,right click,then send to...(well,its F: for me,but I guess not for everybody.)
Anyway,turn your brain off(this can appear way over-complicated,and it's easy to over-think it),follow this exactly,plug everything in,and your DS should bring up the MK3 menu.From there,you will have three options to try to boot something,it's pretty intuitive.
Let us know where you get,there's slicker guys than me that can help...
ALSO-first time you bring up the MK 2/3 menu,hover over MK3 icon,it will give you the option to "Press Y to Format Menu".Do this.It flashes the menu to a small part of the MK3,and it seems to be a little more secure that way.Format the NEO-Cart,also,but flash the menu first.
This new option,combined with flashme,will allow you to boot nds without a GBA pack inserted(Rumble pack for Metroid Pinball!!!),but thats another story.I haven't went that route myself,even.
So keep it in the back of your mind,but the very back for now.
Good Luck.Going to bed,check your progress later.(please give some feedback,it really helps.)I Feel like maybe the guy who is trying to make this as simple as possible for Joe's(I'm a Joe)to understand,because I am aware of my own limitations.
Then be prepared to run around your house yelling happy things.
