Castlevania: The Adventure: Castlevania: The Adventure (GB): Improved Controls

This hack modernizes the control scheme of Castlevania: The Adventure to make it less frustrating to people used to tighter controls by giving the player more control while jumping.

Complete list of changes:

- Belmont can now turn around and stop in mid-air.
- Belmont regains control during knockback.
- (optional) V-Cancel: when the jump button is released, Belmont immediately starts falling again; this allows the player to make smaller hops if desired.
- (optional) Inertia: when adjusting velocity in mid-air, Belmont only accelerates slowly (rather than changing direction instantaneously).
- Belmont blinks rapidly when struck, as in Castlevania II: Belmont's Revenge.

Highly recommended to use in conjunction with the Speed and/or Whip hacks located https://www.romhacking.net/hacks/6762/. You may also wish to apply http://www.emu-land.net/forum/index.php/topic,12055.msg1523232.html#msg1523232 which removes the music from the game in exchange for a significant performance boost.

You can use http://fusoya.eludevisibility.org/lips/ or any other IPS patcher to apply the hack to your Castlevania: The Adventure ROM file.

Version 1.1 changes:

- Knockback control is now regained only at the crest of the arc.
- Blinking iframes.
- (JP) Fixed inertia.

## Patching Instructions

There are patches for each combination of rom (US/EU; JP; EU Konami GB Vol. 1) and for vcancel and
inertia enabled/disabled (see "Functionality" below). Only one patch should be used.
Please note that the US and EU roms are the same. You may wish to verify your rom before patching by checking a hash (see "ROM HASHES" below).

Patch using FLIPS or any other IPS patcher. Please note that gameboy roms contain an internal checksum (which is not actually used by the gameboy!) -- this
patch does not modify the checksum, but if you so desire you may wish to correct the checksum using a utilitiy such as rgbfix.

## Functionality

This hack adjusts Christopher Belmont's control scheme to be more like Mega Man, Super Mario, Symphony of the Night, or Castlevania: Legends.

- Belmont can now turn around and stop in mid-air.
- Belmont regains control during knockback.
- (vcancel patches only!) When the jump button is released, Belmont immediately starts falling again; this allows the player to make smaller hops if desired.
- (inertia patches only!) When adjusting velocity in mid-air, Belmont only accelerates slowly (rather than changing direction instantaneously).
- Belmont blinks rapidly when struck, as in Castlevania II: Belmont's Revenge.

## Compatability with other hacks

Should be compatible with the speed and/or whip hacks: https://www.romhacking.net/hacks/6762/ (apply the controls hack last.)
