Homebrew [Release] PrBoom+ 3DS Port (GPU-accelerated)

[Voxel]

PrBoom+ 3DS Port​

Hi all. After much arduous work, I'm thrilled to finally share a brand new port of PrBoom+ to the 3DS!

This is more or less a straight port of PrBoom+ 2.6.66, with some extra added enhancements exclusive to the system.
Just about everything you'd expect desktop PrBoom+ to do, this port should also be able to do.
The only things it can't do are a few unsupported renderer features (which have been stripped out anyway) and networking features.
In addition, all video modes apart from 8-bit are supported. By default, the GPU-accelerated OpenGL mode is enabled, though the other software-rendering modes are also available should you wish to fall back on them (so far, all modes produce roughly similar performance, with OpenGL being moderately faster)




Features:

• PrBoom+ 2.6.66
• Features both GPU-accelerated OpenGL mode, and software-renderer modes
• Great performance on New 3DS, decent-ish performance on Old 3DS
• Good quality stereoscopic 3D (OpenGL mode only)
• Interchangeable touchscreen mouse and keyboard
• (with touchscreen mouse, you can drag to look around, tap the screen to fire, and double-tap and hold to keep firing - ideal for Old 3DS)

Setup:
Refer to the GitHub repository's README for information on installation, game/mod setup and configuration.

Amazing, right about to test it, and i'll come back with the results!

Keyboard is Present.

For running Doom, not Doom 2, how do I do this? I tried putting in Loading doom.wad on auto, but it seemed to just want to run Doom 2 with Corrupted Graphics.

Thanks for your work! I hope you don't me asking if you're planning to implement some sort of (easier) PWAD selection mechanism?

Yeah it's weird like that when more than 1 IWAD is in the prboom-plus folder, it even happens on the desktop version too.
I just put doom.wad somewhere else for the time being, and I'll work on a solution for it in the future.

Hopefully I will, yeah An easy launcher like some other prboom console ports have would be great!

Just tested it out and it works perfectly fine and very smooth on the N3DS XL, i just didn't understand about the song, how do i add it?

Oh, if the music's already working then you don't have to do anything. I was just making a note that the music isn't using the original instruments, in case anyone was wondering about it. (I'm a bit of a perfectionist )

A simple solution, at least for the 3dsx version, is just to accept pwad path as argv, then we can make xml shortcuts and launch them directly from the HB Launcher.

I haven't had a chance to test it yet, but is the 800x240 resolution mode supported with the 3D parallax layer disabled?

In that case, no music is coming out of my game, only sound effects

Did you download PrBoom-Plus-3DS.zip and extract everything to the SD root?

Oh wow, I never knew about xml shortcuts for HB Launcher until now. Thanks for mentioning that, that sounds hella useful already
And if the shortcuts allow you to specify arguments that get passed to argv, then it should already work in theory.

As for that 800x240 mode, I could take a look into that at some point, sure.

EDIT: Yep, I managed to make shortcuts for both Doom 1 & 2 which work perfectly!

If you wanna do them yourself as well, here's an example:

<shortcut>
    <executable>/3ds/PrBoom-Plus.3dsx</executable>
    <arg>-iwad IWADs/doom.wad -file boiled.wad</arg>
    <name>DOOM (PrBoom+)</name>
    <description>DOOM registered</description>
    <author>Voxel9, PrBoom+ contributors</author>
</shortcut>

Yes i did

the "etc" folder goes too on the sd card root?

 

[ElectricJelly]

After whipping up an XML shortcut thingy, where should one place it?

 

[Voxel]

Yes i did

It does, yes. /etc/timidity.cfg is needed to specify the MIDI instruments.

I just put mine in the /3ds/ folder, but it might detect them in /3ds/PrBoom-Plus as well, though I didn't try that yet.

Oooooh ok , i'll test it, thanks

 

[CrashMidnick]

Thanks Voxel. Working great on O3DS. I tested Doom Ultimate and Doom2 (via shortcut) and they both work fine. Nice to play doom with 3D

 

[Mr_Start]

Oooooh ok , i'll test it, thanks

Working sound!! Perfecto

I downloaded the CIA version of PrBoom+ and it just closes out each time I try to run it from my HOME Screen. Not understanding what I did wrong here, since I extracted everything from the ZIP file to /3ds/ and there's only one wad file (as shown in one of the two pictures). I'd appreciate the help!

 

[Jayro]

Voxel... Buddy... Holy hell, you're amazing!!!

 

[Wavy]

Surprised I didn't see this earlier, this is awesome! Sample-based midi playback and hardware rendering were the two things I wanted most from any Doom port for the 3DS. Congrats on the release!

Edit: Could you be able to add support for ZL/ZR? They don't seem to work

/etc/ folder goes at the root of the SD card. Everything else is set up fine.
It kicks you back to the home menu because you haven't put a game WAD in the PrBoom-Plus folder as well

Thanks a lot for the kind words! And sure thing, that was kinda foolish of me to forget, haha.
