How to get all DMWs to 100%

DMW character has a "progress" bar that will appear anywhere between 0% and 100%, depending on the character. You can check them from the menu.

DMWs are skippable - though skipping them does not impact it counting towards your DMW level.

For Sephiroth, Angeal, Tseng, Cloud, Cissnei, and Aerith, you must see six different 'memories' for each character.
For Genesis, you'll need to see just two memories.
For Summons and Chocobo Mode Characters, you'll only need to see their summon animation once to instantly jump to 100%.

You can get all DMWs 100% even in last chapter!

You can make DMWs appear easier with materias.

these materia can be found in shops later in the game.

shops:

Research Dept. QMC+: From a chest in Gongaga Village, Chapter 10. Missable. Sells the materia for Sephiroth, Angeal, Tseng, Cloud, Aerith, and Cissnei.
Net Shop Shade: From Mission 9-5-4; sells the Genesis DMW materia.
Bone Village: Unlocked via Mission 7-5-3. Sells the DMW summon materia.

And once you have grinded all DMWs to 100% you should get.
