To skip the repetitive process and see final playback, go to 05:04.

Inspired by MarI/O and LuigI/O, I've made my own SMBbot, except that it's not AI, it's what I call an "Artificial Idiot", for it's really DUMB. It doesn't read map, doesn't read level information, doesn't evolve, doesn't have much memory. It basically just jumps randomly, and loads savestates after dying or bumping into a wall.

Yet the performance is very satisfying for such a simple script. It's able to complete the entire World 5 in 04:46 without Turbo, with only 448 retry, and in speedrun style!

5-3 is the hardest stage for World 5, for there's a chance of getting no second lift and Mario keeping falling into the hole. In this video, SMBbot went lucky until 5-4, where it hilariously wasted 44% of the retry on Bowser.

After some manual upgrade, now it can solve every level of SMB with no problem. I'll keep it this way (but a bit smarter) and see how far it can go!
