Which is already amazing. I don't exactly see what more could u possibly want.
4.5 exploit has full control - ROMs, system modding, etc.
6.3 (possible higher) has "user" control - we can do things, as lambstone said, that current games can do.
Obviously nobody's complaining about the 6.3 exploit - an exploit is an exploit. I think lambstone has just been pointing out the differences, people aren't trying to attack the exploit or smealum in any away.
