Aperture Science DS, NEW NDS Homebrew

[Another World]

Aperture Science DS, previously known as Portal DS, is a Homebrew version of the popular Portal game series. The project has been released as part of the Neo Flash 2013 coding competition. It features most of the mechanics found in the series and a level editor inspired by Portal 2's perpetual testing initiative.

So much yes!
I've been waiting for this baby to be released

 

[.Chris]

I've been waiting for this! I wish I still had my DS to test this out, but I guess I'll have to use my Xperia Play with DraStic to run it.
Thanks smealum and lobo!

I don't believe it will work with DraStic as at least the maps folder and config.ini require an sdcard to write to. (DraStic doesn't do R4 emulation yet)

Oh, that's a shame. I'll have to wait a little longer then lol .
(I still got an AK2i but have a DSi with 1.4.5 )

And actually, I just tested on DraStic. It does boot, but just like on my DS, crashes 1-2 seconds after the elevator door opens. It does work with desmume so it probably works with nds4droid (if you want to play it at the speed of a potato).

You Do realize that the Readme states that hbmenu is needed to run this cause itrequires fsnitro ?

Works on my Gbamp CF however …

it seems you can only walk around.

If you could at least use the portal gun.
It makes the "shooting" sound, but doesn't create portals.

I wish smealum would reply to this thread and clarify this.

that shouldn't happen anymore since the latest update I was able to do thanks to your guru meditation report. download it again !

do you mean on your DS, not on emu? it should work. try deleting config.ini if you copied it maybe...

I mean DS.

getting a 404 on both of those. the guru meditation error shouldn't happen anymore with the latest version though.

 

[pasc]

yeah, they are still busy uploading to my Dropbox...

Downloading the latest version from your website works !
The filetrip one is still broken

Suggestion:

make R blue portals and L orange ones.

Other than that: AWESOME

ok so for filetrip I'll see what I can do.
and in your video you're trying to shoot portals on black walls which are "unportalable".
as for controls, you can change them yourself! take a look at the included config.ini file in the asds folder.

Somehow this thing should win I think.

It works so smooth that one wonders why a Portal DS was never realized.

Now for a ridiculous question:
How about custom background music support ?
Lets drop our mp3's inside a /data/apsds folder or something

 

[raulpica]

Probably the most graphically stunning game ever released on DS, and it's homebrew, to top that! Big kudos to smealum

unfortunately it's not that simple. basically the DS has two CPUs, a main one (arm9) and a secondary one (arm7) in DS mode. the arm7 has access to all the sound hardware and the arm9 does not, so usually only menial tasks are relegated to it, such as playing sound and such. the thing is, in portal I use it to run my physics engine ! so not only can it not really spare the cpu power to decode any kind compressed of sound format, it's actually got very, very little RAM left available (I think in this latest version it has like 4KB of ram left out of 96KB). so I can't add any kind of code to decode stuff there, and I can't very well decode it on the arm9 either because, well, it has to run the game so it's pretty taxed itself already. so essentially the only solution would be to use RAW format sounds (which is what I did for the couple SFX I threw in there), but since they're uncompressed, they take insane amounts of RAM that I just don't have right now.
so that's why there's no music of yet; I still have to think about how I might get that to work. but mp3 is pretty much out completely of the picture at this point.


also I just realized that I'd forgotten to switch to higher res textures before releasing.... I still have like 100KB of vram left, so I could get the doors and such to look much nicer, but I guess it's too late now.

About that control ini file:
I changed the bracket from [notouch_controls] to [controls] as stated, however the game still hasn't got
INPUT_R=CONTROL_SHOOTY
INPUT_R=CONTROL_SHOOTB
applied.

Saving and creating levels to the cf card seems to work fine, so dldi or something similar shouldn't be the problem.

why is that ?

Great work smealum !

Fun Fact: Standing under a vertical platform will push you below the map

 

[T-hug]

This looks fantastic great work smealum! Unfortunately I can't test it as I no longer have a DS but I do use drastic a lot with my FC30!

yeah I meant to make the player die in that case but I forgot. you'll find player collisions are rather buggy in general.

btw, just made two videos :
