Super Bhop Bros. is a Super Mario Bros. ROM hack by 8BitPlumber that implements a new "Bhop" functionality where horizontal speed is uncapped when jumping backwards. There are six levels designed to test your Bhop skills.
This functionality also allows for new tricks that you won't normally see in the original game as well. My run makes use of these tricks to beat the hack in record time.
- A left press at 105+ speed redirects Mario back, dropping to -24 speed.
- A left press at 90+ speed in the air redirects Mario back, dropping to -40 speed. Speed must be decreased on the previous frame.
- Any speed decrease at 25+ allows for running jumps.
- Mario ignores walls at -128 speed, which requires a specific subspeed to achieve.
- On the ground, rightward-moving speed will drop to 0 if speed was increased last frame.
- (There was also info about parts of the level design not loading at 65+ speed. I'll hopefully look into getting insights on it in the future.)
* In this case, positive speeds are when Mario is moving right. Negative speeds are when Mario is moving left.
Despite ROMHacking.net coming to a close, you can still find the hack here.
