This hack re-adds the dash button control scheme from the game's prequel, Mega Man Xtreme.
Unlike Mega Man Xtreme, the dash button has been coded to use the Select button, rather than the Start button, this is to keep consistent with the W. (Weapon) Change and X/Zero Change controls.
Save files should be compatible with the unmodded game, but in-case the button config. select gets stuck, use the save file with the hack, change the controls to W. (Weapon) Change or X/Zero Change, then save.
Unfortunately, it wasn't possible to code Zero's airdash to use the Select button, but any proposals to change that will be accepted, along with being credited for doing so.
Known issues:
- It's possible to pause the game in a few places where it shouldn't (while warping, during boss intros), but it shouldn't interfere with anything, dialogue isn't affected by this issue.
- When dashing towards doors using the Select button, it's possible to softlock the game, you can get out of the softlock by changing weapons using the Select button though. Thanks Netmonmatt & Exmotable!
