Hi

not really, it's more about isolating the underlying random method for 
now. We use the OS's rand() but some other emulators are sometimes using 
a different/faster method (see uaerand() in cpu/ or also core_rand() in 
Hatari for libretro).

If we ever want to have our own internal random function (that don't get 
called by other programs) to have reproducible series of random numbers 
then it will be possible this way
