Golden Sun (1st) Help backtracking!?

I'm playing golden sun (the first 1) on visualboyadvance emulator w/ only 1 save state, so i can't acess older files, I went past moggle forest w/o getting force or grow, i can only get so far in Altin Mines, and i doesn't seem like i can go back through moggle forest. If it helps to know, I have the frost and douse psyenergy, and the following djinni: fizz, breeze, mist, forge, corona, flint, quartz, sleet, spritz. I don't have to start the game all over do I? how do I get force or grow again, or backtrack through Moggle Forest?
