4 official rulings from Bandai, last ruled Mar 28, 2024. Straight answers to how this card actually resolves.

How do I count "for every 2 suspended Digimon and/or Tamers, gain 1 memory" for this card's <When Digivolving> effect?
Count the total number of you and your opponent's suspended Digimon and suspended Tamers, then gain 1 memory for every 2. For example, if you have 1 suspended Digimon and 1 suspended Tamer while your opponent has 2 suspended Digimon, the total would be 4 and you gain 2 memory.

If I have 2 or more of this Digimon in the battle area, or if me and my opponent have 1 or more each, does this Digimon itself become unable to unsuspend during the unsuspend phase because of this card's <All Turns> effect?
Yes, that's right. Other [BT12-057]/[Quartzmon]'s [Other than this Digimon, all Digimon and Tamers don't unsuspend.]'s effect will also activate, so if there's more than 1 of this Digimon in play, none of them will be able to unsuspended during the unsuspend phase.

If this Digimon is in play, and 2 suspended Digimon perform DNA Digivolution, will that Digimon unsuspend?
Yes, it unsuspends. DNA Digivolution treats unsuspended Digimon because of the DNA Digivolution as new Digimon in the battle area. This card's effect does not affect it since it's not treated as a suspended Digimon becoming unsuspended

If this Digimon is in play, do other Digimon or Tamers with effects such as <Reboot> or "Unsuspend this..." become unable to unsuspend?
Yes, that's right. Even with the "Unsuspend this..." effect, they don't unsuspend.
