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?
TODO: rewrite to call things 'opcodes' and 'operands'
add bank switching for higher 128 bytes
- add a flag in the ~zero-page
try writing:
- a 'greater than' routine
make coding forms!
