Why did you include the slide in MM1 & MM2? Cool feature, but changes the original gameplay. Pretty sure there's a game genie code to enable sliding in MM1/2 so no need to add that option.
Because I didn't see any reason not to, since the slide doesn't break any bosses or levels. It just adds a new potential strategy that can be used on bosses. It actually IS the game genie cheat, just patched in with GG Guy for ease of use.
Just make an optional patch on the same submission. Doesn't hurt to have options.
Will you make patches for the Japan version as well?
That's actually a good idea, what if I just make the slide, extra magnet beam ammo, faster fire rate, and 5 bullets on screen at once separate patches? That way, if somebody doesn't like a specific feature they can just choose not to apply it.
I'll see what I can do about the JP version.
