What's New:
- New banking handling so we only move pointers - not blocks of memory. Renders all 5200 Super Banked games playable.
- New NTSC palette from Trebor's Pro Palette (NTSC_LUM1_HOT 5200).
- Added 5200 512K Super Cart banking.
- Improved Pokey emulation (around the random scanline start value - fixes one Acid800 test).
- Improved keypad debounce for Star Raiders.
- Improved sound handling to reduce pops/clicks. Increased the sample rate on the DSi for improved fidelity.
