Homebrew doom

[GameFreakDude]

This homebrew application is based on PrBoom. It will never be able to run Skulltag / Zandronum mods, which is what MM8BDM is. You would need an entirely new app that ports ZDoom to the 3DS, which would be a huge undertaking for an incredibly niche market.

IIRC, ZDoom can compile for ARM, but I believe this effort is aimed at ARM Linux, and has some issues. I wouldn't get too hopeful that ZDoom could run such mods at full speed on a 3DS if it were ported well, or even that it could run full speed in the first place.

Can this run Doom 2? also, Can this run Doom 2 Mods?

 

[GameFreakDude]

Sure.

 

[darklordrs]

Darn it, forgot it was built in Skulltag\Zand.

The ability to practice my E X T R E M E MM8BDM M I N D G A M E S on the go would be amaaaaazing.

Seriously hope that there will be a GZDoom Port so possibly Brutal Doom can be run.

I know jack shit about porting and homebrew, but i believe that would be too taxing for the 3DS to handle.
But i'd love to be pointed wrong in this case.

Is it possibile install as CIA with FBI? And is stable for play and finish without bugs/crash?

I haven't built the cia version in a while. it should build from source though - make cia
I never got around to making a proper banner for cia. And I am currently using a modified ctrulib that boosts the thread priority for ndsp - without this change the sound gets all choppy particularly if you enable 3D with the slider.

So the best for now is to launch with the HBL, right? ^^
Is stable for play and finish it without bug or crash? Or it is better to wait?

Thanks for the update but latest build freezes every time i try to start a new game. Previous .3dsx and .cia build working fine.

@elhobbs Is there anyway you can make (or tell me how to) the cstick act like the mouse?

you can bind it to turn left and turn right in the control settings. if you want it be more mouse-like you will need to modify the code. the touch screen currently acts this way starting at https://github.com/elhobbs/prboom3ds/blob/master/arm9/source/ds_vid.c#L380
you could implement something similar with irrstCstickRead.

Thanks! I've got it bound to turn left and right, but it isn't precise.

yep, that is why I suggested the code change.

hi elhobs,

can you please provide us with an updated cia build or could you also provide us with the modified ctrlib so that I can try to build cia myself? Thank you

[Kioku]

How did you manage to bound it?

In the settings. It binds it as a digital key press, so it's not better than binding it to say the y and b buttons.

I do not want to supply a modified ctrulib. You can make the change yourself if you are so inclined. The change is extremely minimal. I changed 0x31 to 0x18 on the following line - https://github.com/smealum/ctrulib/blob/master/libctru/source/ndsp/ndsp.c#L485
make cia
Should build the .3ds and .cia versions
As a note the ctrulib change is not strictly needed. It will build and run (the 3dsx version anyway) without this modification to ctrulib.

Okay, did as you say (thank you) but I have run into a error when i try to build "make cia" I get;

So for kicks, after getting the feedback from above, I decided to copy the makerom out of the resources folder to /home/cloud/ and renamed makerom to prboom3dsresourcesmakerom as it was being called for but that gives me this error;

I'm using Ubuntu. The makerom packaged with your release is makerom.exe so I instead compiled makerom from source and replaced it in the resources folder. Then I edited the Makefile and changed the two references to makerom.exe to makerom.

Any help would be appreciated Sorry for the lengthy post.

Also, the .3dsx and .elf compiles just fine

I would say you are on the right track building the Linux makerom. I am guessing that it is a newer version that takes different parameters. the command line in the makefile ,and probably the rsf files as well, will need to be updated. The files I created are shit - minimum needed to get it to run at the time.

Edit: and change the \ chars to /
