Homebrew blargSnes -- SNES emulator for the 3DS (WIP)

[VinsCool]

yes, should run fine on the CFW


I'm a Gateway user so you're on your own.

Thanks

May I ask how you converted it? Every time I tried I kept getting errors.

Compiled from source, stripped the elf and built it with makerom, using an rsf based on GameYob's one.

Here's the RSF if anyone's intereseted

yes, should run fine on the CFW


I'm a Gateway user so you're on your own.

If you don't mind me asking (and that goes for StapleButter as well), what are you using to build the 3dsx version? I have the latest devkitPro with devkitARM and ctrulib. It compiles, but with a tons of warnings, and it crash-and-burns when attempting to load a ROM. I kinda want to try some tinkering, but I can't do that when even attempting to build v1.1 crashes on me.

I'm curious as well as I'll soon (relatively) get a 3DS XL and using the Ninjax (or whatever they call it now) method, this could be useful for someone like me, I think.

Get the latest ctrulib from https://github.com/smealum/ctrulib
build it and replace the files at DevkitPro\libctru with the new ones


BTW there's really no point in releasing .3ds versions of homebrew if they use CSND for sound.

There should be only .3dsx for ninjhax and .cia for gateway/CFW


Here's the compiled ctrulib I used (commit 58b988ab9729678a34f7ebf42ff6a43a0a1fdf7c)

 

[Seraphiel]

If someone wants to try a CIA version with sound, here's one compiled by myself.

Note that it's not as stable as the .3DS version uploaded by StapleButter and it's been uploaded by me, not him.
So if any game runs fine, thank him. If any game looks broken don't complain because he didn't release this in the first place because he thinks it's not ready for release anyway.
I'm uploading it because there's no other CIA option available.

By the way, it seems they fixed the sound issue in ctrulib. I was getting a crash when loading the games when I built it with ctrulib 0.1.0 (only the screen was black instead of white like in GameYob)
I updated to the latest version today and games are running fine with sound.

I can confirm it works for me so far, installed it using the bbbmenu and sound is on if somewhat not in the best quality but game runs smoothly as before (playing Rockman and Forte).

Edit : hmm after trying to exit blargsnes with home button and pressing close it got stuck on Closing software, will give it another try and see if it was a random thing or not.
Edit 2 : this time i exited using the red X and it worked perfectly so would just stick to that

On the 1.19 build on a 2DS, I'm getting Super Mario World flickering randomly into and out of transparency.
I'm not asking for support for this, I just haven't seen this mentioned and it may be a 2DS-specific issue you wouldn't have noticed otherwise, so just a possible heads up!

build from piratesephiroth (based on latest git commit) fixed this.

 

[xantoz]

I just upgraded ctrulib to the latest version and compiled the latest git of blargSnes and it seems to work now. Still quite a few warnings though.

 

[ZeroShift]

Built fresh from git. Earthbound now freezes when doing anything at file selection.

On the other hand, it's looking a lot better!

 

[the_randomizer]

Would it be feasible for someone to capture brief video? It'd be awesome to take a sneak peak

 

[piratesephiroth]

The games that work run at full speed and look and sound pretty much as good as it can get.

Megaman X has only a minor glitch in the menu, highlighting 2 weapons instead of only the selected one.
Aladdin shows some background objects flickering at the botom of the screen sometimes.
Zombies Ate My Neighbors seems to run without any issues.

not from me.

 

[DiscostewSM]

Well, the version piratesephiroth built now doesn't have the Eng translated version of Final Fantasy IV alternating errors of "Unsupported VRAM mode" and "Small sprites" during the loading of the starting cut-scene (which brought everything to a crawl and ultimately a crash). Unfortunately, button presses don't seem to do anything during that initial cutscene, so you are stuck on that first bit of dialog on the airship.

Great work StapleButter.

 

[piratesephiroth]

not from me.

unfortunately youtube doesn't do 60fps, hah
But yeah the games run very smoothly.

 

[VinsCool]

Your build is working just fine by the way
window, mode 7 and some more graphic shit is working.
Amazing work of StapleButter

 

[the_randomizer]

Actually, it can now support 60 fps on Chrome, as long as the video is encoded at 720 or 1080 at 60 fps or IE 10 with HTML5 http://kotaku.com/youtube-finally-supports-60fps-and-it-looks-awesome-1652460542

Just for the sake of clarification


VinsCool Seeing that at 60 fps, and the sound emulation's actually quite decent already, dayum that looks awesome

YT does 60fps (when setting to an HD resolution).

 

[VinsCool]

Yes, sound is very good actually. some click and pops here and there. lack interpolation and echo effect. but still, pretty good

 

[the_randomizer]

I'm sure Gaussian interpolation and ADSR (which helps with echo I think, acronym for Attack Delay Sustain Release), FIR sampling, ADPCM, a few things to work out, but man, full speed, this emulation is proving to be quite impressive
