This release fixes a bug with the new pixel fill feature (horizontally smeared screens will show up), and also reduces the ROM size from ~63KB to 8080 bytes.

This release has the PPU updates collapsed from a loop of 4-24 passes per CPU instruction to a single pass which should be essentially identical to the old approach for a simple scanline renderer. The cpu_instrs test ROM runs in about half the time after this update from my testing.

A matching symbol file is also included for debugging purposes.

This release replaces the original super inefficient OAM scan, drastically speeding up the PPU rendering.
