+TODO
+----
+
+- The readme claims there is a GI-SP0256A-AL ADPCM on the PCB. Needs to be
+ emulated.
+
+- Verify all clock speeds
+
+- I'm only using colors 0-15. The other 3 banks are mostly the same, but,
+ for example, the color that's used to paint the gradients of the sky (color 2)
+ is different, so there might be a palette select. I don't see anything
+ obviously wrong the way it is right now. It matches the screen shots found
+ on the Spanish Dump site.
+
+- What do the rest of the ports in the range c0-ce do?
