Any MGS games that have control options?

I can't stand "O" having the function of what's typically assigned to "X" on a Playstation controller and other controls that Kojima forces on us in Metal Gear Solid.

In any of the many ports and sequels, do any allow the user to change controls?

i don't know why setting up your own button assignments is still not a standard on consoles. I mean one by one, each button, not shifting between presets. You don't have that on PC, they'll hunt you down. So I'd check to see if there's a PC version. Even if the vanilla doesn't offer it, I'm sure there's a mod out there that allows you to do it.

I know what you're talking about though...the worst is that O evades and goes prone...because those couldn't be any more opposite. Like, Press R2 to fire and hold it to surrender!

It used to be more common back in the PS2-XBOX days. With the 360-PS3 generation it went the way of the dodo and I doubt it's ever coming back, since basically nobody cares. Then their controller breaks because they keep clicking the stick to sprint in CoD or lock enemies in Dark Souls, and then they complain. When lazy programming costs the consumer extra money.

I think the 360/PS3 remasters of MGS2, 3 and peace walker might've had optional control layouts, but I'm not totally sure as it's been quite while since I played them, and I no longer have them. I might be wrong.

Didnt MGSV have a more conventional scheme? I havent played it in ages but thats kinda what I remember.
