Homebrew doom

elhobbs · Nov 6, 2019

There are a bunch of different versions of prboom floating around at this point. I would recommend that you use the version that is directly in the gut repo here - https://github.com/elhobbs/prboom3ds?files=1
Just grad the cia or 3dsx. Then make sure you add the prboom and doom wad files. This is not compatible with enhanced wad files as this is not an enhanced engine.

Hi I’m kind of new to homebrew and was wondering if anyone could help me figure out why prboom keeps crashing when I try to start a game. I get as far as difficulty selection and then the game crashes.

Here’s the crash report for anyone who can help.

The wad files go in the root of the sd card right?

Wouldn't it make more sense to clear up this confusion by quickly putting out a new release on the github page? The last release, 0.5a, is two years old and missing a lot of bugfixes. Most users aren't going to go looking for the updated files in the repo.

Ok, thanks!

Just been giving version 0.7 a try after having missed the most recent updates. The 3D looks really really good but it’s not ‘quite’ there - can’t put my finger on it...perhaps it’s the gun position in relation to walls? Perhaps it’s just my eyes lol!

the 3dsx launches fine from the home brew folder but for some reason the cia can’t find any wad files and hangs the system..

regardless, thanks for continuing your work on this: it’s my go to game on the 3ds

Regarding the 3D, on my N2DSXL, the mugshot in the HUD definitely looks off. As for something else (and to be honest, it's a request IF its feasible) what would be required to utilize GenMidi for music playback instead of the current implementation?

3d on a 2ds - huh? And what/where is GenMidi?

the 3D is far from perfect. Without switching to hardware rendering I am not sure how to make it better. The sprites are always going to look odd regardless.
Did the cia launch for you with the previous versions. The cia requires the wad files to be in a specific location (described in the installation instructions). It works fine on my 3ds. I should probably make it not hang the system and print out where it is looking for the wad file ...

ElectricJelly · Feb 2, 2020

I don't know if the odd rendering (the DoomGuy's mugshot is just an example) is indeed directly related to the complete lack of 3D on the model that I happen to have. I'll upload a pic tomorrow. As for the music playback implementation whatever, I was referring to one popular way its done on prBoom for PC. The better IMO of the two Vita ports* uses it (not to imply that the way it works there is tranferable), and more info is on the DoomWiki at https://doomwiki.org/wiki/GENMIDI and https://doomwiki.org/wiki/MUS

If that sort of playback is implementable, it will vastly increase the number of PWADs able to be enjoyed accurately. If its not practical without a lot of work, no one should blame you, IMO.

*Neither of which are limit-removing BTW

Morning! My fault - I’m an eejit: I’d named the folder prboom not prboom3ds. Sorry: it’s all fine now.

the hud problem the other poster mentioned is that doomguys head is slightly bigger than the rectangle it sits in..

Glad you sorted it out. The hud issue - not something I care to address. It is not a big deal to me. If someone wants to submit a pull request then that is fine.

GENMIDI is a lump in the wad file used to configure the sound card. This implementation directly plays the MUS lumps from the wad file without converting it to midi.it already uses GENMIDI. I still have no idea what you are requesting. This use the dosbox opl emulator if that helps.
To be clear I am not saying the hud issue (such that it is) has anything to do with 3ds/2ds. The phrasing of your statement made it difficult to understand what you were trying to say. You started with”Regarding the 3d” then went on to comment on the hud on a 2ds - which has no 3D effect.

ElectricJelly · Feb 3, 2020

It sounds then like the music being 'off' isn't an easy fix. My hope with the request was to direct you towards an angle you (hopefully) weren't aware of. Sorry for eating up some of your time.

No the hud issue doesn’t bother me either - hadn’t noticed it til it was pointed out!
Thanks again for the port

How do i boot up other wads besides doom1 and doom2? Im trying to play sigil, plutonia, and evilution.

Unrelated note: some monsters will disappear by clipping through walls or glitching over ledges and will be put out of bounds.

edit: i have figured out how to play other wads, but i think the enemies clipping out of bounds is an engine quirk, i cant fix it from ingame settings or the cfg file.

30yoDoomer · Feb 18, 2020

The monster clipping has been solved. Use a newer release. https://github.com/elhobbs/prboom3ds/releases

Put the wads in the /3ds/prboom3ds folder. Doom 1, 2, plutonia, and evilution are selectable when it is first started. Sigil is a pwad. You need to use the compat version. Then add it as a pwad through the in game menu. If I recall correctly it is a pwad for doom 1 - and it does work. No music though. Double check on the doom version though.

Is there a way for it to play expansions?

Drop files in /3ds/prboom3ds/ then edit prboom.cfg to add your wad name to the wadfile_1,2 fields.

As an aside, Retroarch added a Prboom core, but it crashes during menu navigation and doesn't perform well on the o3ds.
