Raizing:
- Adjust timing for audio in sorcer and kingdom (again)
- Adjust all cores and meet all timing constraints
- Swap pll properly to 94.5 mhz for SDRAM compatibility, adjust all clocks and frequencies
- Add 2 build profiles for each core, one for development purposes (fast build) can get you an RBF in 8 mins, but not meet timing constraints 100%, and other is normal production build, which is about 20 mins. You can switch between the profiles in quartus UI.

Inferno:
* Gave joystick analog inputs precedence over digital (d-pad) inputs if both were triggered at the same time. This resolves default mapping issues some users were having if they had not defined gamepad inputs inside the core.
