Accomplished:
- All memory Instructions implemented.
- Started writing test benches for arithmetic and control flow instructions.
- Wrote the first draft of CPU parts of the design report.
- Looked into some other options for the NES USB controller.
- Learned what the DAA instruction does (binary coded decimal addition)
Next Step:
- By the end of spring break, I hope to have a fully implemented CPU that passes all hand-made tests.
Other Notes or Concerns:
- Progress is ahead of schedule.
- The Altari controller can be connected directly to GPIO pins. With some modifications it might be a possible substitute for the USB NES controller.
