# Dev notes — 2023-08-05

- consider refactoring assembler to do something more like 'tokenize, then call helper functons'

- consider an extended system:
  - add a byte in the ~zero-page to act as a flag for display mode
    - 0 = 1 byte per pixel (default)
    - 1 = 1 bit per pixel
  - add another 16 ops (or fewer)
    - rotate left / right (or shift?)
    - AND
    - OR
  - more flags?
  - another register?
    - would require several new ops
  - add binary input/output to assembler

- consider gamepad vs. hex keypad
  - stick with hex
  - but permit gamepad since that's a subset (NES layout = 8 bits/bytes, depending on mode)
  - look at how uxn does it?

- <mark>TODO: rewrite to call things 'opcodes' and 'operands'</mark>

- add bank switching for higher 128 bytes
  - add a flag in the ~zero-page

- try writing:
  - a 'greater than' routine

- make coding forms!
