Very happy to see more local play in homebrew!!! Did you get the code from the Snake game?

No, I only studied the documentation of uds.h of ctrulib and the devkitPro example, then I wrote the code on my own. I didn't even know there was a local play homebrew before.

Version 0.6.1 has been released.
Main feature: Further improvements to overall system stability and other minor adjustments have been made to enhance the user experience
In detail: painted over "F1", "F2", "F3" buttons in main menu; fixed lemmings entrance position (again); fixed memory leaks in multiplayer mode.
Note that v0.6.1 network protocol is not compatible with v0.6. Network protocol backwards compatibility should be better in the future.

Any idea why the .cia version doesn't give me any sound but the 3dsx version (Launched via hbl) does ?

 

[bayleef]

Have you dumped the DSP firm?

Clone of Lemmings for DOS. Version 0.6.1

Setup:
Download the attatched file lemmings.zip. It contains .cia and .3dsx version.
Fill the subfolders of /lemmings folder with data from DOS Lemmings (see README.txt files in these subfolders). These files are not included in the archive since they are protected by copyright law. In order to run the software, at least one subfolder must be filled. You may fill any combination of subfolders, depending on the Lemmings games you own.
There exist free demo versions (that include only 4-5 levels each), which are all supported by Lemmings for 3DS. Since the demos were released for free, it should be legal to link to a download location. You can find free demo versions of Lemmings games here.

Have you dumped the DSP firm?

That did the trick

Thanks

Anyone know how I compile this into a .cia file please, I would like to replace the banner.wav in the source code if this is allowed.

 

[bayleef]

Of course this is allowed. See licence.
You need a git client and an environment to build homebrew applications, i.e. devkitPro and libctru.
Check out the repository with the following command:

git clone --recursive https://github.com/esoteric-programmer/lemmings_3ds.git

Replace the banner.wav file.
Then, at the command line, go into the repository and build it from source:

cd lemmings_3ds
make

A subfolder called "output" will be generated, containing lemmings.cia (and many other things, but you may only need the lemmings.cia file).
If this does not work, post any error messages or other problems.

I get the following error,

build/src/draw.o
src/draw.c:3:18: fatal error: sf2d.h: No such file or directory
#include <sf2d.h>

EDIT, seems I need ctrulib

build/src/draw.o
src/draw.c:3:18: fatal error: sf2d.h: No such file or directory
#include <sf2d.h>

EDIT, seems I need ctrulib

The project does not use sf2d any longer. It seems that I forgot an include statement when I removed sf2d. I have updated the repository. Do a

git pull

in the lemmings_3ds folder to get the fixed version that can be built without sf2d. Afterwards please try again to run make.

 

[Connorsdad]

So I replaced banner.wav with LETSGO.wav (I renamed it to banner.wav) and installed the .cia from the output folder, the sound doesn't play when the icon is highlighted, I get a beeping sound :/

Any ideas ?

BTW, thanks for your help its much appreciated

I guess, it is a problem with bannertool. Unfortunately, I don't know the reason, but one of the following may solve the problem:

• banner.wav is a 16bit stereo 44,1kHz wave file, while LETSGO.wav is 8bit mono 7092Hz. Maybe the unusual sample frequency causes the problem. Try to convert your file to 44,1kHz sample frequency (maybe change resolution to 16bit and channels to stereo, too).
• Maybe the duration of the sound is too short. Try to add a silence of approx. 1.1 seconds at the end of the sound file. The original banner.wav has a length of 1.997 seconds, while LETSGO.wav has a length of 0.895 seconds. Your final length should not exceed 2.0 seconds.

If both suggestions do not work: Does it work when you build the cia in your environment, but with the original banner.wav?

BTW, thanks for your help its much appreciated

You're welcome.

 

[Connorsdad]

All working now
You were right regarding the wav file properties, I did as this post said https://gbatemp.net/threads/convert-soundfiles-to-wav-working-for-banner.399472/#post-5725664

Again thanks for your patience and time in helping me

Version 0.6.2 is available now.
Changes:

• fixed wrong colors in FUN22, TRICKY14, TAXING15, MAYHEM22
• create cache on first boot; afterwards the game starts significantly faster
• CIA file uses homebrew logo instead of copyrighted nintendo logo
• lemmings folder can (but need not) be moved into the 3ds folder to unclutter the SD card's root

 

[bayleef]

Version 0.6.3 is available now.
Changes:

• SFX19.WAV is played (if it exists) when a lemming falls out of the level
• In single player level selection menu, completed ratings are marked with an asterisk (now you can see whether the last level has been solved)
• Fixed two bugs concerning animated objects (water, traps, ...)

This is probably the last version of the game (unless someone reports a really horrible bug). There are still some open issues, but I don't want to implement all this stuff alone. If someone wants to help me, I may change my decision.

Lemmings is crashing on my 3DS, B9S, 11.5.0-38U. I tap 1 player, hit A, and an exception occurred, and I need to shut down

if its not just a fluke, i'd say not being able to properly play is a big Bug indeed D:

Still works ok for me. N3DS, latest stable Luma with L2 + Cache, B9S, 11.5.0-38U. I never got around to adding sounds, just music. Don't know if that matters or not.
