Where are the best places to collect power ups and still get a good time? I know this might have been asked before.

For Warpless: 1-3 and 1-4 if you want to zoom zoom. If you want to take it safe: 1-1, and 1-2 so you don't have to do pipe jumps Hope this helped

Thank you! I meant for any% but this will help!

To go ULTRA fast, 1-2 and 4-1

To go OMEGA fast use the pellsson rom to start off with fire Keepo . But ye 1-1 and 1-2 are the safest and probably the best for any%

This site with all maps on smb1 is a godsend for that question - http://ian-albert.com/games/super_mario_bros_maps/

It shows all hidden powerups for every level
