Is Super Mario Bros. in Nintendo World Championship 1990 the complete game?

In the Nintendo World Championship 1990 game, is it possible to completely play through Super Mario Bros?

By this, I mean not collecting 50 coins, but continue playing normally taking warp zones and going through the levels as fast as you can.

Could you eventually reach Bowser in level 8-4 and rescue the princess? Or are there unavoidable coins in the middle which would guarantee that you would get 50 coins before that happened?

Solution 1:

The answer is yes, it is possible to finish a complete game
Here is the end screen:

After this the game repeats as in the original Mario Bros, that is, starting from World 1-1, with the goombas replaced by buzzy beatles

We are not allowed to change world with the B button
The score and coin counts reset to 0, but the timer of the game cart continues

Once the timer is up, only the current score in mario is counted as the NWC score
