Well, first check if there's enough free ram. There's a rom call for
that, but I don't exactly remember its name (_enoughmem or something).
You give the amount of ram needed in HL and it will return a carry when
there's not enough. When the carry isn't set, it's safe to use the mem
starting at (FREE_MEM_START).
