The PS1 controls were never added to PC, simply because at the time, the technology didn't exist in commonality, to use a coontroller with the PC, and though PC controllers existed, by the time Diablo 1 for the PS1 was launched, Diablo 2 was likely under production, and using Controllers on the PC was nothing short of a rarity outside of racing games which, are doable on Keyboard, they still suck on one.

The original never had controller support. The PS1 isn't the original.

As for your RSI, mentioned in later posts, you can just find a 3rd party program that can either allow you to click multiple times with the mouse set down, or, you can simply fool your computer into thinking you're pressing a mouse key, when really you're using a keyboard key.

You can do this by simply looking up the Ease of Access center on your computer, go to Keyboard, and set up Mouse Keys.

If you can use a controller just fine, you can just use the Spacebar to click instead. Realistically, all you need is fingers for 1-8, and the thumb just sits on the spacebar.

The PS1 port split of from Diablo around version 1.04. It had a completely different render with better light and colors and lower resolution graphics and lower fps animations. There where also several optimizations to the game for it to run on the low amount of memory of the PS1. Probably for this reason the changes where never merged back in to Diablo, but it's also worth noting that the port was not made by Blizzard them self's.

All that being said controller support will be added to DevilutionX within the next couple of months so you might wan to hold out for that.

Yes.

Use a program called AntiMicro it is free and opensource: https://github.com/AntiMicro/antimicro/releases

I use it to bind the left mouse button to a xbox controller so that I use my thumb to click. It works in any game just make sure to run antimicro as Admin.

Game controller support has finally landed in DevilutionX, if you are willing to test it you can do so by downloading the latest release (0.5.0 https://github.com/diasurgical/devilutionX/releases) and the exe from the latest nighly https://4234-143324737-gh.circle-artifacts.com/0/devilutionx_x86.exe

You can see the control scheme here:

We are still working on some improvements for the mage, but it's good enough for the warrior and rouge to be fully playable I would say. Feedback is welcome.

Damn i really want to try this because i can't use mouse and keyboard. But my eyes crossed and brain started smoking looking at the instructions to use

Well good news, we made a release just two weeks ago that include controller support, so just hit download and your will be good to go.

Since my last post we have also finished the implementation so that it also works nicely with the sorcerer.

I hope someone ports Diablo to Original Xbox with controller support, That would be sick.

Edit
I just tested with a Xbox360 controller and works surprisingly well. But is there a button to attack in the direction i am facing without any target? also, is it possible to turn off the auto target? by just pressing two buttons and it could atomatically do everything, from attacking, picking up stuff and open doors.This without even moving the joystick, but apart from that it works and feels great.

Thank you for the reply! Looking forward to the 360 port and hopefully an OG Xbox port do happens.

Edit
It seems someone is already working on this:

He he, hadn't seen that video, I recognize some of my menu quirks probably from around 0.4.0, this thing is taking on a life of its own

Is there any option to play on GOG version on LAN?

DevilutionX supports kan and internet if that's what you are asking

I played with my friends on LAN. When i run Diablo with DevolutionX i dont see LAN mode and my warrior(lev 10).

"Client-Server TCP", it works both on LAN and across the Internet (host needs to port forward).

Did you put your save game in the correct folder? Check the ReadMe.

In realtà le cose stanno diversamente,
la vesione su PS1,completamente pensata per gamepad si è rivelata alquanto eficace,con ben 14 tasti in totale,grazie al tasto R2 pigiato insieme a uno degli altri 7 che raddoppia le opzioni disponibili.
Per non parlare dei tasti L1 per la vita e R1 per il mana,che fanno consumare tutte le pozioni presenti nell'inventario e,esautite quelle,passa poi alle pozioni della cintura.
Grazie a questo sistema hai a disposizione fino a un massimo di 48 pozioni disponibili su un solo tasto,e la cintura diventa a tutti gli effetti come una spia del carburante che si accende,mostrando al giocatore che in realtà le pozioni dell'inventario di quel tipo sono finite.
Quando,su PS1 a velocità fast,sei da solo a difficoltà Hell e sei davanti a un gruppo di avvocati e di Hell Horror(l'equivalente dei Blood Knight),e non vuoi tornare continuamente a ricaricare la tua stafff of apocalipse,(che io non uso mai perche non mi serve)sai gia che consumerai molte pozioni di life e di mana in pochissimi secondi,perdere termpo a ricaricare la cintura è semplicemente una perdita di tempo che per i meno avvezzi alla tastiera puo rivelarsi fatale,e giocare con l'inventario aperto per cliccare sulle pozioni riduce troppo la tua visuale,non vedi piu come si muovono i mostri attorno a te,va bene giusto per Diablo alla fine quando rimane solo.
Questo è solo un aspetto ma ce ne sono molti altri,sempre a vantaggio del controller,ovviamente configurato come quello della PS1.
Giocando da molti anni su entrambe le piattaforme ti posso dire che c'è solo un grande limite per la versione PS1,l'uso della magia Teleport,con il mouse fai in un attimo,con il game pad ci vuole circa un secondo per spostare il cursore di un intera schermata,quindi in un ipotetico scontro online PVP probabilmente un grande giocatore con mouse e tastiera batterà facilmente un grande giocatore con gamepad,per il resto quello con game pad è piu efficace.
