Real Battle Reward

In MMBN3, if you're NetBattling on Midweight, Heavyweight or Tri-Battle level and playing in Real mode, when the Results screen pops up, there is a 1-in-32 chance to get a special reward chip. This only happens if the winning player has not yet received Balance/DeltaRay. When this happens, the losing player does not lose one of their own chips.

When choosing the reward chip, the game will make a list of every Standard chip that neither you nor the other player has yet. However, all the Virus Breeder chips are excluded from this list, so you can't get them this way.

If this list of potential chips is empty, then the winning player will receive Balance or DeltaRay depending on their version. In other words, if both players' Libraries combined result in a completed Standard Library (Virus Breeder chips not counted). Otherwise, the game selects a chip rarity based on your Busting Level:

Busting Level	Chip Rarity Chance
Lv. 1	★: 100%
Lv. 2	★: 100%
Lv. 3	★: 100%
Lv. 4	★: 50% ★★: 50%
Lv. 5	★★: 50% ★★★: 50%
Lv. 6	★★★: 100%
Lv. 7	★★★: 50% ★★★★: 50%
Lv. 8	★★★★: 100%
Lv. 9	★★★★: 100%
Lv. 10	★★★★: 100%
Lv. S	★★★★: 100%

Next, the game will check if there are any chips in the list of potential chips that match the selected rarity. If there are no chips found, then the game will decrease rarity by 1 and check again, until a chip is found. If there are still no chips found at this point, then the game will instead increase the rarity by 1 and check again until a chip is found.

Finally, the game will choose one of the available codes of that chip at random, except for * code, unless * code is the only code that chip can have. Each code has an equal chance to be chosen.

Trivia

• Any region Mega Man Battle Network 3 can link up with each other (eg. Japanese can connect with a North American copy). However, since the English version has received bug fixes, battles are susceptible to be desynchronized on both players’ side.
