Performing a charged move roll cancel (RC) in Capcom vs. SNK 2 (CvS2) on a Mixbox, keyboard, or leverless controller requires precise inputs within a tight 2-frame window to exploit the roll cancel glitch, which transfers the invincibility frames (i-frames) of a roll to a special move. This technique is particularly useful for characters with charge-based special moves, such as Blanka, Guile, or M. Bison, and is applicable in grooves that allow rolls (C-Groove, A-Groove, N-Groove). Below is a step-by-step guide tailored for Mixbox/keyboard/leverless controllers, which use WASD-style directional keys instead of a joystick.
Understanding Roll Cancel
Roll canceling is a glitch in CvS2 that allows a special move to inherit the 27 invincibility frames of a roll by canceling the roll’s startup (within 2 frames) into a special move. This makes the special move invincible during its startup, significantly enhancing its utility for characters like Blanka (RC Rolling Attack) or Guile (RC Sonic Boom). The technique is not available in CvS2 EO’s ranked mode, as roll cancels were removed in that version, but it works in offline/unranked modes of the original game or arcade versions.
Blanka’s RC Rolling Attack
Blanka’s Rolling Attack is a charge-back move ([B], F+P). Here’s how to RC it:
Hold A (back) for 2 seconds to charge.
Press LP+LK (e.g., J+K) to start the roll.
Within 2 frames, press D (forward) + Punch (e.g., J for LP or I for MP).
Input sequence: Hold A → J+K → D+J (or D+I for MP version).
The result is an invincible Rolling Attack that can pass through fireballs or other attacks.
