Opcodes e0 and f0 fail when pointing at ff00.

That is to say, in the cases of "e0 00" and "f0 00", the parser treats it as "LD (0xFF00 + (0x0)),A" and "LD A,(0xFF00 + (0x0))", instead of going to (DAT_io_0000). If this could be fixed, possibly around the same time as removing the IO pointers for LDH operations, that would be wonderful.
