XBoyAdvance - GBA/GBC/GB/SGB/SGB2 Emulator for XBox v20

http://forums.xbox-scene.com/index.php?showtopic=493160

What's new :
- Reverted back to 1.7.2 core
- Implemented relevant portions of VBAsmooth code
- Delayed auto-load save states to avoid strange slowdown
Sometimes when the auto-loading of save states happened,
the GBA emulation would be very very sluggish, like the timing
is off. Seems the GBA emulation needs to "warm-up" for a second
before loading the save state.

Notes
-----

Usually newer cores mean better cores, but this does not seem to be the case
with the last 2 releases. I haven't seen any information that indicates
any games play better with the 1.8 core, (quite the contrary actually) so
I've backported to 1.7.2.

In the last version, I stated that I wouldn't do this, but I was talking
about 1.7 since that seems to be the fastest one. This version, however,
now appears to be faster than even version 9 thanks to the vbasmooth additions.

Check the sticky this was already done in there, unless this was meant for people to talk about the emulator that is, the news is usually in the sticky. Nice to see someone contributing some news for it though.
