for NES
Differences from the official version

The NES can't replicate Cookie Clicker pixel for pixel. So I have to make a few compromises to adapt the game to the platform's capability.

Cosmetic

Big cookie, buildings, upgrades, and statistics are on separate pages instead of fragments of one window. (Apparently Cookie Clicker itself does this when run in a tablet web browser.)
The first five buildings (Cursor through Mine) are shown from the start.
"Short numbers" uses metric suffixes (k for thousand, M for million, G, T, P, E, Z, through Y for septillion) to save room. For example, after 🍪9,999,999 is 🍪10.0000 M.
Buildings' screens display payoff time, the price of the next building divided by CpS per building. They also display "base rate" (before production multipliers and "twice as efficient" upgrades) and "upgraded rate" (after "twice as efficient" but before CPM and kittens).
Cookie counter in status bar doesn't increase quite as smoothly. Shouldn't be very noticeable to players who build a Frenzy+Lucky bank.
Reset is called Retire and has a story justification.
Ticker: Moved to bottom; displays both headlines and popups. Only one message can be displayed at once.
Ticker: Many headlines have been shortened.
Ticker: Non-Grandmapocalypse headlines remain included in the rotation after Grandmapocalypse begins.
Menu: No clipboard means no "export save". If using a PowerPak, you can trade .SAV files.
Menu: Cosmetic settings cannot be changed. Unlike the PC, where settings allow the player to adapt the game for stronger or weaker processors, the NES has identical processors in all machines.
Stats: Achievements are called "awardments" because some platforms have policies against using the word "achievement" for anything but a platform-provided mechanism.

Gameplay

Upgrades are grouped into categories, and the player must buy the earlier upgrades in a category before buying the later ones. For example, the player must buy "Cheap hoes" to unlock "Fertilizer".
The statistical distribution of golden cookie and reindeer spawn times may differ slightly.
Time machines add only to the bank, not "Cookies baked (this game)". You cannot retrieve a cookie that was never baked in the first place.
Retire unlocks at 1 trillion cookies baked all time. That's enough to earn 1 heavenly chip, and enough to buy the first 10 prisms.
Buildings cannot be purchased when the price exceeds a week of production (72 Frenzy+Lucky rewards) or when the player already owns 255 of them. This means two upgrades and two awardments related to cursors are not present.
Business Day season (fools) will not be implemented because it's useless for players.
Unlike in the web version, where resetting reverts to a seasonless state, the 24-hour effect of a season biscuit persists across Retire but ends once Heavenly chip secret is purchased. This allows experiencing each season's early game without having to buy a new cartridge during each season.
No dungeons. If you want Zelda, you know where to find it.
