Tricks

Quick walljumping

When the player is in a shooting or slashing animation, he'll return to the wall quicker, allowing you to wall jump again earlier. This will speed up the wall jump process.

To optimize vertical speed release B for one frame when the vertical speed RAM address reaches -960, so that the speed goes like -1152 > -1088 > -1024 > -960 > -896 > 64 > -1152 > repeat.

Attack combos

In the ZX series certain moves can be chained into each other, ignoring (but resetting) invincibility.

Moves that can be combo'd:

Model X (ZX): First charge shot > second charge shot
Model ZX: Shot (regardless of charge) > Air slash > Air spin slash > Walk slash / Dash slash > Triple jab > Tenshouzan (ZXA)
Model H/HX: Tornado > Electric orb (ZX) > Air slash / Air dash slash > Walking slash / Dash slash> Triple jab
Model L/LX: Ice Dragon / Ice Platform (ZX) / Ice Block (ZXA) > Jump slash > Ground slash
Model F/FX: Two Buster shots (which arms are used is not important) > Megaton Punch / Fireball > Megaton Punch > Fireball (note: Megaton Punches or Fireballs must be hit closely after one another, or the combo won't land)
Model P/PX: Standard kunai, all four hits of a single button press > Cross Star
Model OX (ZX): Charge shot > OIS second charge shot > OIS Shinkuujin > Air Slash > Air spin slash > Walk slash / Dash slash > Triple jab > OIS Ryuuenjin
Model A (ZXA): Homing shot > Charge shot

Miscellaneous data

Horizontal movement speed

Models, Human and Reploid forms:
- Accelerating from standing still to walk: 128 speed (0.5 pixels per frame), for 5 frames
- Walking or moving in the air: 512 speed (2 pixels per frame)
- Dashing, airdashing or dashjumping: 896 speed (3.5 pixels per frame)
- Human swimming: 256 speed (1 pixel per frame)
- For underwater speeds, multiply speed by 0,75. This does not count when using Model L, LX or OX.
Pseudoroid forms (ZXA):
- Buckfire:
  - Standard dash: 768 speed (3 pixels per frame)
  - Attacking dash: 896 speed
  - Dashjumping: 896 speed
  - Buckfire does not slow down from being underwater
- Chronoforce:
  - Swim: 512 speed
  - Dash: 896 speed
  - When releasing the dash or directional button, decelerates by 32 speed per frame.
  - Vertical swim speed is horizontal speed multiplied by 0,75.
- Rospark:
  - Walk: 256 speed
  - Jump: 128 speed
  - Rospark does not slow down from being underwater

TODO: add other Pseudoroid forms

Vertical movement speed

Vertical speed decelerates by 64 speed every frame in the air, and 32 speed underwater
Jump starting speed:
- Models, Human and Reploid forms: 1280
- Buckfire: 1472
- Rospark: 693
- Vulturon: 1280
- TODO: add other Pseudoroid forms
Airdashing upwards (Model H, HX): 768 speed (3 pixels per frame)
Vertical swimming speed:
- Chronoforce (ZXA):
  - Normal: 384 speed
  - Dash: 672 speed
  - After releasing the up/down and/or dash button, decreases speed by 24 per frame
Max falling speed on land: 1791
Max falling speed in water: 896
