amiibo registering

amiibo are registered[1] every time an amiibo is used.

Whenever an amiibo is registered:

  • AmiiboMgr determines if it should reset its daily amiibo use history (stored in the AmiiboTouchHistory flag)[2].
    • If less than 86400 seconds (1 day) have elapsed since the game was launched, don't do anything.[check]
    • AmiiboMgr then computes 10000 * now.year + 100 * now.month + now.day. If the value is different from AmiiboLastTouchDate (which would mean that a day has elapsed), the AmiiboTouchHistory array is cleared.
  • The amiibo UID is inserted into AmiiboTouchHistory. Only the last 100 entries are kept.
  • It is also inserted into AmiiboTouchHistoryTotal. Only the last 200 entries are kept.
  • Finally, AmiiboLastTouchDate is set to 10000 * now.year + 100 * now.month + now.day to update the last amiibo usage date.

Logic[3]

A SmallHit will happen 20% of the time.

If the amiibo has been scanned 0, 1, 2, 3 or 4 times, you'll get a GreatHit 20% of the time. If you didn't get a GreatHit, the game will ensure you get a BigHit.

If the amiibo has been scanned 5 times or more, you'll always get a GreatHit. In this case, the BigHit table is ignored.

For BigHits and GreatHits, the game uses the 'Remain' tables if Find_4Relic_1stClear is set, 'Parasail' if IsGet_PlayerStole2, and 'Normal' otherwise.

Final drop nums after RNG (note: negative values are set to 0)
Normal SmallHit BigHit GreatHit
GreatHit, no BigHit N - GH SH 0 GH
No GreatHit, BigHit N - BH SH BH 0
