Level Editors Question

[gamemakerg]

A while back i wondered if i could edit my levels on my hacked psp. when i tryed i discovered several things.
1 i can run windows useing dos box
2 i discovered that the rf built in level editor took up too much memory and in turn it couldn't run on the version of dosbox

I am now wondering how much ram the level editors take like the unoficial ones that are avalible for genisis 3d and rf.
I would like do work on my games even when i am away from my computer and at my bosses.
thanks in advance
btw if anyone is interested in this when i get it to work i will give it to you with the editor on it and instructions to put your levels in it
ps: im talking about these(and the one that is pre included):
