Switching between Emu's

I wanna switch between 0.25 and 0.2a but the Iso data is only being recieved to 0.25(my default emu).How do I make it to where 0.2a plays the iso game instead of the other and vice versa, you know, to change it back?

thanks captain obvious.


that's why I only posted in this one, http://www.emutalk.net/chankast/33232-switching-between-emus.html



and the forum was slow as hell when I tried to post only one.
