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

[DiscostewSM]

I'm trying Gaussian interpolation with the audio. Got some progress, but unfortunately, it's causing various distortions. The intro music to F-Zero sounds ok until certain notes are played, to which it screws up during their playback. Megaman X doesn't seem to have a problem.

I meant to report on this weeks ago (or I probably did but didn't post the shots) but anyways, Super Metroid does this strange thing in this spot of Maridia. Specifically to the left of the highlighted spot on the map. Upon entering that section the screen goes blank or with what appears to be ground texture or something. The music keeps playing but I can't do anything. Also Ninjhax user here (not sure if that matters) and this is with blargSnes 1.2.

That "ground texture" is water. Does it freeze there, or can you do anything, like shoot? It may be a windowing issue, which for the most part seems to be working correctly in latter unofficial builds. If you upload your save that's as close to that part as possible, we can check.

Oh okay, looks like blue ground to me haha, it seems like it freezes but I can't really tell cause the music still plays fine. I can upload my save, what's the extension? Is it the .srm that's in the rom folder?

Yes, it has the .srm extension. If you can hear sound effects when you make various actions, like shooting, charging, or rolling into a ball and using bombs, then it's likely not frozen.

Ah alrighty, here you go. I tried shooting and laying bombs but no sound from those actions.

I have a question: Would it be possible to make the emulator be able to read the rom from a zip file so you don't have to extract it?

 

[DiscostewSM]

Would have been nice to have a save spot closer to where the problem occurs, but anyways.

An interesting bug nonetheless. Was thinking it was windowing problem, but it certainly isn't that. The area was running fine until I got close to some of those flying enemies, and then I got the same problem you demonstrated. The area went black with just the water showing up, and everything froze. Might be an infinite loop on the CPU-side, as the music on the audio-side is still running.

Oh yeah my bad on that. And interesting, hmm.

Ok, I believe I got Gaussian interpolation implemented. I misunderstood what parts the barrel shifts affected in ASM commands.

Wow that is cool from you Discostew

I just want to contribute (and relieve StapleButter of having to do some of this stuff), yet I really don't know much about audio, lol. I'm just reading documentations like FullSNES, and trying to see if what it details is something I can do myself. I only wish I knew enough to figure out why the audio makes clicking sounds during playback.

Dayum, you guys are on a roll, that's awesome!

I heard that v1.1 cause some problems with various progs, so I didn't update to it. If v1.1b fixes that, then I may update.

I too haven't updated yet. Is it best to stay on the first release of ninjhax for blargSNES? blarg is the one emulator I care about right now so I don't want to update and hurt compatibility with it

I'm on 1.1 and Blargsnes is working just fine.

Can you access the settings, running blarg 1.2 with Ninjhax 1.1/b ? Because every time I try, it crashes CN.

Everything works for me using 1.2 on Ninjhax 1.1b

Try re-installing blargsnes

 

[Myria]

Is there a newer build than 1.2 that I can download? Compiling from source is a huge pain, especially if it involves a disaster like git...

Also, go and download this and extract it into the 3ds folder on the SD card. You can download Blargsnes 1.2 on it for extra security.

Thanks. I simply reinstalled blarg and it works fine now

Also, today I've tried the latest build of CitrAGB, which now utilizes dynrec. The improvement for GBA emulation is simply amazing. I can't wait to see how much dynrec would improve blarg...
