The duplicate characters flag (dc) enables characters to show up in the seed in more than one slot. Because certain characters are required for some questlines and every Jets of Time seed may be 100% completed, this is handled in the following way: each character is shuffled at the beginning of a seed as normal, and these characters retain their name. The name of the character controls their ability to unlock questlines; the character with the default name of “Frog” will be the character who needs to come to the Magic Cave to open up Magus's Castle, for example.

When the flag is enabled, other characters may be shuffled into these slots at random. So while there will only be one character named “Frog” (for example), and that character will keep that name, any of the other 6 could come into the slot. They will have their own sprite, but with Frog's color palette. The sprite determines which character has joined your party, which techs they can learn, and which items they may equip.

The flag can be applied using default random settings, or a player may further control manually which characters are in the seed and how many of them appear.

When Duplicate Characters is enabled, most characters have a dual tech they can perform with themselves. Currently they are all of the same tech on top of each other. (The “Change from Vanilla” column remains in case we need to note additional power given to the base techs; otherwise these techs were created for Jets and don't exist in vanilla)
