HELP!! Instructions For Install of MAPTHIS!

OK,
HI! I cant believe what my psp can NOW do!! I have an old ( 1.50 OS) PSP that I dug out of my closet... I havent picked this thing up in years!!! After reading about the homebrew movement, I decided a couple of weeks ago to dig mine out and see.. The PSP GPS has really sparked my intrest.. As a Touring Sound Engineer, I really had used my PSP alot on the road but got bored with the games but this will bring new life to the old unit....
------------------On to the Unit-----------------------------
I recieved my psp-290 gps reciever yesterday. and after much debate and reading, loaded the new OS..

( I will have to say that all of the new features are way cool!) I also went out and bought a few 2gig sticks as well.. all now formatted.
___________on to the Mapthis! questions_______

Which version should I use? 0.499 or?

The Directory tree on my stick should look like this?
psp/game150/? and ?
