Hi Justin3009, thank you for updating the mod with V3.0 and it's definitely a great work! Although I have discovered a few bugs with this version after some testing:
1.) When X obtains the Z-Saber and his Hyper C. is also charged up, switching from the Hyper C. back to the X-Buster would result in X not able to fire up the Z-Saber until either he dies or beats/quits the stage. This bug appears to be a major show-stopper for the gameplay.
2.) Zero's second air-dash is only possible to be performed when "Forward + A" are pressed. Pressing "A" alone without the Forward button can only perform a single air-dash, not double.
3.) Although this was an intended design, but Zero's double-consumption for his sub-weapon usage isn't ideal. The sub-weapons are easily emptied while the bosses are still alive. The game also becomes increasingly difficult if Zero dies during a boss-fight and re-spawns after already emptied his sub-weapons.
Z-Saber bug tested with the following password:
Looking forward to the amazing V3.1 that would resolve these bugs!
