Super Mario Bros. 144 Fireworks

Super Mario Bros. 144 Fireworks

This is a warpless playthrough with the following restrictions:
You must spawn 6 fireworks at least once in each of the first 3 levels of each world (every non-castle level).
You must beat every level in the game

6 fireworks X 3 levels with fireworks per world X 8 worlds = 144 fireworks.

6 fireworks spawn when Mario touches a flagpole with the timer ending in 6.  For example: touching the flag with times of 276, 366, 126, etc would all spawn 6 fireworks.

If you fail to spawn 6 fireworks on a particular stage, you must intentionally game over at some point and make use of the continue code (after a game over, hold A when hitting start back at the title screen) to restart that world.  If you need to replay levels to get back to the one you messed up, you do NOT need to get 6 fireworks again on those levels.  For example, if you mess up 7-2 you will need to intentionally game over, use the continue code to start back at 7-1, play 7-1 however you wish and then try again to get 6 fireworks on 7-2.

If you somehow fail to enter the continue code or beat a world where you didn't spawn 6 fireworks on each level, you can start from the beginning of the game and use the warp zones to get back to whatever world you need to access

After you've successfully spawned 6 fireworks at least once on every non-castle level, you can go on to beat the game.  Time ends upon hitting the axe in 8-4.
