Hello,
I'm trying to use the TI-8x emulator for linux called TilEm and I have intalled it successfully,

This is what it says in the README file:
The first time TilEm is run, you'll probably get an error message
as you don't have the right files. Create a directory named ~/.TilEm
and copy your rom files there with the following syntax:
* xp.rom for the TI-83+ ROM file
* x3.rom for the TI-83 ROM file.


I'm getting that message that tells me to move the rom to ~/.TilEm
and copy the rom files there with the following syntax:
* xp.rom for the TI-83+ ROM file
* x3.rom for the TI-83 ROM file


What exactly am I supposed to do there? Any help would be greatly appreciated.

which bit don't you get? you've made that directory? you've got your rom files? so move them to that new directory... if you don't have the rom's, you need to find them from somewhere out on the big wide world interweb.

Thanks for replying I don;t understand what the ~/. means in ~/.TilEm.

~ means your home directory. ~/.TileEm means a directory called ".TilEm" in your home directory.
