ROM and RAM info about the game, found by Quick Curly


Death Hopping
Frame perfect. Press A on the right frame before hitting lava/spikes and you'll jump from them without taking damage.

Jumping when shooting
Just like Death hopping, you can jump while shooting or while charging a shot, allowing you to mantain a lot of your momemtum and saving significant amounts of time.

Jumping while tired
Q Boy gets tired after his power meter runs out. If you want to keep moving while this happens you have to do the same thing as death hopping, only your movement is a little bit more stricted.

Float Jump Management
This is a rather unique mechanic in Q Boy. Use this to jump from higher distances and more wide areas. Calculating when to use this move is key.

Damage Management
Taking damage is an useful way for an inmediate refill in Q Boy's power bar, it also saves time when getting tired. But you can only get hit 3 times, unless you get a heart.

Jumping Straight
Ways of jumping straight are either to not hold a direction, or press direction keys simultaneously on frame perfect inputs. This doesn't apply with falling, though.

Ledge Grabbing
With enough height, one can reach a block and cancel any falling/jumping animation.

Wind Blocks
In the game, there are blocks that can push you through 4 directions, of course, moving right is the prefered way.

Bumping Blocks
You can bump blocks in this game, and it can ruin your vertical momemtum a lot.

Water Boosting
Stage 2-4 has a unique mechanic where theres a water current where moves you very far from the screen, although you also take damage from.

Block Floating
Block+noblock+otherblock wakes you walk through the empty space between 2 blocks.

Shooting Combos
This is a cool mechanic where if you shoot an enemy, it gets pushed back. Against a wall, it kills it, but if you hit it agaisnt another enemy, a chain reaction can occur, very useful in the 1st boss.

  TODO: Research the hammer minigame + RNG. Add a crap ton of gifs as well...


Stage 2's Ice Physics:

While standing still, you slide at the direction Q Boy is currently facing. This is intended, but it can be abused on moments when you need to stand still.

Anti-slipping though, isn't. You need to move left or right while standing still to avoid this. Getting tired + a direction will cancel any sliding around.

Hovering in Midair
Exclusive to Stage 2, there is a glitch where when you get tired, and you don't press any direction keys, Q Boy will slide, but when he gets tired and he reaches the edge of a block, he'll... levitate for some reason.


A very specific trick involving frame perfection all around. Push left or right 1 frame, then push both left+right and press A in another frame (thanks emulation) at the same time, you'll jump backwards. Potentially saves time since you can move right while shooting enemies left, and viceversa.

  TODO: Add EVEN MORE gifs...


"Fake Lag"
Sometimes, Q Boy will stop moving when he lands on the ground. It only delays for 1 frame, although it's still unknown why this happens and how to avoid it.

The Ceiling
You can bump the ceiling, and get stuck horizontally in it... weird.

The Timer & Frame Rule
Improvements must be big to even counter the frame rule in the timer. If the timer doesn't stay at a certain number, it's almost worthless, if it does, then go for it. It's kinda complicated to figure out at first, but you can get the gist of it soon enough, it's just a matter of paying very close attention to the timer's number.

Random Game Crash
The game crashed on me once, on FCEUX, on Stage 1-1. Reasons of the crash are still unknown and currently it hasn't been replicated since.
