Parts/functions
- Define state bits
- include easy ROM/RAM chip(/internal) declaration; don't want to exclude MagicFloor nor MMC5/6 from "correct" description
- Logic
- Arbitrary address bus size for chips?
Convenience addtions
- Conditional operations (optional but helps user-side…but makes it harder program-side)
- some header fields as parameters might be desirable (mirroring, chip sizes)
- on the other hand, they are different boards in some manner. Perhaps only as solder-pad options?
- Cartridge connector pins as predefined signal names, or a module (to allow picking 60 or 72-pin)
- Option to autoconnect power, ground, address lines that are not in file
- like connecting PPU_A[0:7] to CHR_ROM_A[0:7] if CHR_ROM_A[0:7] do not appear in the description)
- Also autoconnect CIC
Extra function thoughts
- Outputs (e.g. LED)
- Inputs (e.g. DIPswitch, solder pads)
- Describing expansion port devices in similar manner
- Describing controller port devices in similar manner
Hard Part
- Expansion audio (analog, can involve extra oscillators as VRC7 audio does)
