Ok so Im playing firered rom on the no$gba emulator.

When im in pewter city I can collect the hidden pokeball that is north of the gym.

But for some reason when I am in the mt.moon cave I cant collect the hidden tinymushrooms and such.

There is some hidden tinymushrooms and bigmushrooms in some rocks in that cave.I know they should be there but for some reason when I click the rocks I cant get those hidden items.

Any one know why im having this issue?
