Savestates

[andres-asm]

So... I have been messing with the savestate code and I... kinda fixed it But I don't know why.

Example: If you make a save in SFIII it works fine If you close RA and restart it, and load the state it hangs

Example: Make a state in sfa3 mid fight Load the state, works fine Restart, load state right away, garbled music

This fixes it:

So with the CPS3 hack and this change we have netplay working better under a common platform. For cross platform we still have to fix the savestates so they are always the same size
