Since the original was controller based, is this capable of it too or is it only kb/m?

It was?

While it was indeed ported to consoles, it wasn't really designed in mind of controllers. (They were still butt for PCs when it came out) However, you could probably use a tool like AntiMicro to rebind controls to a joystick.

Don't know about the Playstation port but the original 1996 PC release was designed with the standard input methods for that time in mind. Which was and still is the keyboard and mouse.

Nowadays you probably could get it to work with controllers via some input conversion software with little to no effort, but why would you want to do that in the first place? After all this is the PC version and not the Playstation port which likely was completely overhauled to function with controllers.

Edit: Or what @Darvond said.

You gotta be kidding. The game had 2 shoulder buttons for mana/ health pot and 4 buttons for the skills. You dont need anymore buttons than that.

Plus I see its a 1 click 1 attack meaning you will ruin your mouse like that.

Plus its just easier to play with controller for me with RSI.

Hahaha... Sounds like your Diablo PS1 experience was watered down to say the least if you could have comfortably played it, according to you, on an SNES controller with 4 face button (+2) and 2 shoulder buttons. Try to forget everything you know about the PS1 version and play the real thing.

Revelation: PS1 emulators exist.

What part of having RSI issues is so funny to you? Some people .... Reading comprehension is bad too. I dont recall ever saying anything about SNES...

You don't take your RSI seriously as your priority is playing and whining about video games, so I didn't take it seriously either. You said we only need the four face buttons and two shoulder buttons for D1 on PC (which could not be less true). That happens to match the layout of the SNES gamepad. I put the image out there of someone playing Diablo on an SNES gamepad to demonstrate the absurdity of your wishes and of your indignation that they were not fulfilled.

Look, obviously you have no clue about RSI and causes, effects. I advise you to be quiet on matters you have no knowledge as you are making yourself look like a fool. Get educated then come back and we can talk.

The PC mouse causes effects such as dorsiflexion - I will give you minute to go look it up.

Controllers are more naturally fitted to sooth this but what do you know anyways.

I have my answer that it does not come configured with a controller.

If you must use a controller for this game, then maybe you could try something like xpadder or Joy2Key in order to map keyboard keys to the controller, but I've no idea how you'd get the mouse element to work. AutoHotKey scripts could map mouse control to the controller functions so maybe that's possible (i.e. mouse on one of the thumbsticks or d-pad and the controller buttons for left and right mouse click and some of the game key functions). Though I can't see that you'd get enough mapped for the purposes of the game.

Yea thanks. I was hoping this would come to steam so I could use a steam preconfigured controller setting but I doubt this is going to happen.
I've got some experience with a couple mappers and am debating if I should mess with config files or not. I am looking into some modding atm to see whats possible.

Thanks again.

I dealt with RSI as a teenager. At early signs and warning from my doctor, I reined in vices, like excessive gaming, and today my wrists are fine. I'm sorry if you've let it go beyond the point where you can deal with it through nonsurgical means. If it's so bad, I'm not sure why you're wasting your time and comfort typing here.

I don't know what kind of mice you're holding from what perverse angles, but I hold my mice and trackball with a neutral wrist, in neither palmarflexion nor dorsiflexion. The trackball facilitates this automatically, while mice require a wrist-rest, an ergonomic standard since the '90s (which you apparently did not use :(). While my gamepad posture is more dynamic, I often hold them with one or both wrists in dorsiflexion. Considering I'm trained in anatomy and kinesiology, I can actually understand the Wikipedia description you read and, most likely, misinterpreted. Love that I'm being implored to educate myself by the guy who started a thread based on the false premise of Diablo being "originally controller-based," though. You're trying too hard here, and too little in real life. Get off the PC.

Look good for you. You know a thing or 2. You dont know me or my circumstances so just answer the original question. You come in here spouting crap that I never asked your opinion of nor do I care after this post. Shit happened while in military is all Im going to say. Vertical mice help but dont alleviate the issues. Controllers are nuetral position for me and I try to find games that support them so I can still enjoy bits of life. Glad I serverd to give folks like you the right to spout nonsense. Sometimes I wonder why tho. The world had one off its rocker and I dont care much for the hate floating around these days in social media. You happy now - go away.

Best of luck with your maladies, and priorities.
