OK, I've updated the file selector, so hopefully BeebEm will allow any filename length:

i finally got round to trying this and its great thanks a lot.
One problem I've found is that in some games I cant use 2 button presses. For example in strykers run I cant fly and shoot as I need to hold up while pressing fire. I also cant jump diagnolly as I need to press up and left at the same time.
Not sure if this is down to the emulator or something to do with my key layout. I'm using the arrow keys and space
