99 Warp Spheres!

I managed to open all 12 chests in the Omega Dungeon in FFX! After trying the 'timed' advice in help forums, I experimented and - after a lot of trial and error - this is what worked for me.

room with 2 chests = wait 1 second on the 1st chest; waited 1 second on the 2nd chest;

1st room with 3 chests = wait 1 second on the 1st chest; waited 2 seconds on the 2nd chest, waited 2 seconds on the 3rd chest;

2nd room with 3 chests = wait 1 second on the 1st chest; waited 2 seconds on the 2nd chest, waited 2 seconds on the 3rd chest;

room with 4 chests = positioning is important; you have to be standing on the brown tiles, not the green tiles, then I waited 1 second on the 1st chest; waited 3 seconds on the 2nd chest, waited 3 seconds on the 3rd chest & waited 2 seconds on the 4th chest.

I am still so hyped about that. Wheee!
