Diablo for the Nintendo Switch

Nintendo Switch Port of DevilutionX (Diablo)

How To Play:

• Extract contents of diablo-nx.zip release into SDMC:\switch\diablo-nx
• Copy DIABDAT.MPQ from original Diablo game disc or GOG version.
• Launch diablo-nx.nro
• Note: Hold R on any installed game and launch it. Do not use photo-album to launch. If you use photo-album, the homebrew only has very little memory available, and the touch keyboard doesn't work. This is true for all homebrew, not just Diablo-NX.
• Enjoy :)

devilution-nx's Issues

diablo-nx not launching in Yuzu (tracking issue)

Since I'm making commits to Yuzu (Switch emulator) I will be looking into this. For context I think it will be easier to debug from this side than emulator-side. I'll create a sister issue for them as well once I figure out how to compile and rule out anything dumb such as not checking the right directory.

Steps

1. Copied DIABDAT.MPQ and contents of diablo-nx.zip to AppData\Roaming\yuzu\sdmc\switch\diablo-nx.
2. In Yuzu (master), File -> Load File... -> diablo-nx.nro.
3. Yuzu shows loading bar for 1s, followed by game immediately closing back to the rom list.

Notes

• Does create a diablo.ini in yuzu\sdmc, so it is doing something before closing.

Issues

• NRO game title/header metadata is missing.
• Game immediately closes.

No right click?

There doesn't seem to be a right click mapped. I'm not able to use MP pots or Scrolls

Vile stand not on level 15

I reached level 15 and have explored the entire level and i can't find the vile stand which holds the Lazarus staff.
Without this the game is unbeatable and you can't progress.
Is it a bug or am i missing something?

Can't right click in inventory = no drinking elixers or reading books.

Since there is no right click of the mouse mapped, users can't drink elixers or read books in any way. (Making the sorcerer unplayable).

Can’t attack barrel when monster is nearby

When I am right next to a barrel I cannot select it to attack it when there’s any monster on the screen. I can only attack the barrel when all monsters are gone.

Port on RetroStone/Retrorangepi

Any chance to see a port for RetroStone / Retrorangepi? :)

It's a game console running armbian (a debian variant for Allwinner SoC). It has a dpad and 10 buttons.

Could you help giving hints about what should be modified for the controllers?

Chest are completely ignored if enemies are nearby

Any kind of chest are completely ignored when an enemy is nearby. There needs to be a check that if we press the Y button it opens the nearest chest regardless if an enemy is nearby.

Not working on latest firmware 16.0.1

Will this ever be updated?

NPC speech out of nowhere

Sometimes when you are inside the dungeon a text overlay appears and display NPC speech, even with voice. It’s weird because the times it has happened there’s no NPC near to trigger a speech.

I wonder if it’s a game bug or port bug.

No limit on stats increase

Once in the dungeon, I can just press R to open the character panel, use the left stick to select any stat I want and press B to increase it as much as I want.

There seems to be no check to limit the stats increase.

Multiplayer Crashes Atmosphere

In addition to the already created keyboard missing issue (so unable to test entering an IP to play multiplayer over TCP/UDP) creating a multiplayer game via loopback crashes Atmosphere.

I don't know if the solution is possible, or if it's worth removing the multiplayer option from the menu to prevent having to reboot the console.

Game speed

Would be nice for future request game speed

-Normal
-Fast

QOL patches

Hi,

Would this devilution version be compatible with devilutionX patches?
Cursory looks seems to suggests so, but wanted to double check.
I'm after the autoclick mod specifically, since I do not wish to wear our my controller buttons.

https://github.com/Manuel-K/devilutionX-QOL-patches

It fails to compile

In file included from SourceX/miniwin/dsound.cpp:2:
SourceX/miniwin/dsound.h:3:10: fatal error: SDL_mixer.h: No such file or directory
#include <SDL_mixer.h>
^~~~~~~~~~~~~
compilation terminated.
makefile:312: recipe for target 'obj/dsound.o' failed
make: *** [obj/dsound.o] Error 1

up/down/left/right hard to press

Using the left joycon up/down/left/right are difficult to get. The diagnols seem to be hit 90% of the time.

Initial Launch crashes

Initial game launch crashes console. After reboot it works fine. Is it because Diablo.ini isn`t initially created?

No way to open Quest log (Q)

It seems with the new mappings there’s no way anymore to open the quest log.

I can use right stick to move the mouse pointer over the quest log button, but there’s no way to click it.

Pressing + during video crashes console

Perhaps we need a flag to check if a video is playing and redirect the + button at that time to do a left mouse click to skip the video scene.

Pressing a button immediately after a level transition will cause an immediate level skip which you cannot escape from

I tested this in devilution-nx initial release (0.9) as well as 0.92, 0.94, and compiling from latest available code and it happens in every build.

If you immediately press a button such as A right after going down or up a set of stairs, you immediately transition to the next floor forwards or backwards, depending on which direction you were going, but your character is not in your view port and you are essentially softlocked unless you load a save.

I haven't used devilution on PC so I don't know if it's some debug feature in the base code, cursory glance at erfg12's pc controller fork and devilutionX at commits and issues I didn't immediately see anything mentioning this issue so can't really tell if it came from changes here or elsewhere.

Made a couple new characters and could replicate every time, I'm using the MPQ from an original diablo disc if it makes any difference.

Keyboard for entering name

A keyboard is needed for entering a name and creating a multiplayer game.

No commit history from upstream

Could you maybe rebase on upstream and apply your commits again so we get full commit history? I think if you made a new branch, rebased the branch on upstream, and cherry picked your commits. Then force pushed it into master, you would have done it successfully, restoring lost history, for the benefit of mankind.

Benefits:

• Due credit to the 35+ developers that spent a combined 6000+ hours to make this port possible.
• It's easier to maintain your port, rebasing on upstream, or cherrypicking commits later
• It's easier to fork your port, lets say by someone who wants to port it to another console.
• It's easier to study your source to learn from it.
• Quite sad to delete history, even if it was by accident.
• Easier to upstream your changes while fully attributing your contribution to in the commit history.

No input at all

Sorry for making an issue, but I've been struggling to fix this.

When I run this the game opens, sound plays, and it takes me to the menu, but it seems I can't input anything at all (pressing any/all buttons does absolutely nothing).

I'm using version 0.95 of this package, and am running 10.1.0|AMS 0.13.0 on my switch...

Do you have any pointers for me?

Pressing + or open inventory near a dungeon up/down glitches

All sorts of weird glitches happen when you open inventory or press + near the dungeon up/down staircases.

Most of the time it makes my character invisible and disables movement.

An easy temporary fix would be to detect if you're near a staircase and disable all button presses except for movement. But, that wouldn't be a good permanent fix.
