Teardown Time

OK, it's time for me to finally tear down the PPU logic and build it back up from scratch the correct way. Before, I was calculating values and offsets to tables using C++ variables (seems obvious right?). Now, I am using processor registers just as the real NES would. This will not only speed up my emulation, but will also fix some problems, as games expect certain registers to be modified -- and by me not touching it, it's causing problems.

Wish me luck, this is going to be one of the hardest parts of the whole emulator!
