I'm a total newbie here, but I love that someone else out there thought X3 would be better if Zero were playable -all the time- . I really hope the person with this idea is still working on it and if a patch is available I would love to play test it. As for the bit about disabling Button Remapping, and making the X button the permanent "Buster" button I would like to add one thing... if you disable remapping please make sure that "R" is the dash button, when I played the first Megaman X I found that having it set that way is far more practical and comfortable than always having to "d-pad double tap" as you can Dash with R then Jump with B and gain momentum (for jumping to far ledges, or doing longer jumps from a Wall Slide) while still being able to shoot with Y (or in this case, use the Z Saber). Also, how will the Saber function in this game? I'm hoping it will be like a quick slash as it is in X4 and in the Zero games on GBA.
Hm..I might have to do that. Or at least remove the ability to change any button to the X button. If not that, maybe add an option where you can change that to.
