# 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?
|
||
|
||
- [ ] 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
|
||
|
||
- [x] make coding forms! |
