1. Expanded Framelimit range from 20 to 120 in case someone wants to run a little faster than full speed but still controllable not like wild OFF.

Browse source 
2. Fixed a bug (for Win 32bit) that reports "No possible memory base pointer found!" even when there IS valid memory base found.

3. Made Metroid Prime 2 (maybe also other games) boot
PS: There is definitely some initialization problem with Dolphin (not found exact location yet), which prevents Metroid Prime 2 from first time booting (If you boot some other GC game first, stop it, then MP2 can boot without problem).
So I added an instant BP hack that can make MP2 boot even at first time.
And I've tested all my games to guarantee it won't break any game that already boots before this hack.
