Homebrew [SNEmulDS] Rebirth the project and update it for the last DKP

Thanks. Merry Christmas to you too.

NTR (DS mode) is unsupported, see:

The usual steps to download/use SnemulDS are as follows:
Head to https://bitbucket.org/Coto88/snemulds/

Pick your branch of choice, if you have a TWL unit (DSi) and Unlaunch installed, you can use "sdd1" branch from the drop down gray button, then scroll down until "Latest stable release:", click the link, download the latest build, extract ALL the files from "release/arm7dldi-twl" into your TWL SD card, root path. If it asks to override, yes to all.

Now boot "ToolchainGenericDS-multiboot.srl", choose "SnemulDS_sdd1.srl" and the game you want to boot. It's that simple.

Thanks, I think the problem was that there was a typo in the file name

First of all, happy new year, I hope today is a good day and you have a great time in the company of your loved ones.

With these advances that have been made, one day we will be able to see Super Mario RPG running on SnemulDS?

Feliz año nuevo desde México!

Probably not in DS Lite, maybe in a SNEmulDS version exclusive for New3DS.

Feliz año nuevo desde Iztapalapa para el Mundo

Es gracioso ver cómo hay bastante gente que hable español por aquí jajajajaj

I was referring to the TWL version, with the recent addition of the ssd 1 branch I see a lot of opportunities

Happy new year from Chile! México es país hermano! lml

SuperFX in DSi is not possible due to current Snes9X SuperFX being LLE (or a hackish LLE mixed with HLE).

1) SuperFX is 21.4Mhz so you can imagine the 1/10th cycle rule doesn't work @ 133mhz TWL CPU. 133 / 10 = 13mhz (a.k.a only theoretically SuperFX 1 HLE games could run full speed on TWL)

2) Keep in mind the SNES APU is 1.024Mhz(1024000khz), and an assembly core runs more or less fine on ARM7 @ 33mhz (the 1/10th cycle rule applies here) provided it's written in assembly only and only in assembly. So it runs full speed, and what actually SnemulDS does.
I've tried running C SPC700 core before in ARM7 and runs slow as hell, sort of like 3-4 samples per second @ 32000khz audio timer playback.

CX4, DSP and S-DD1 are HLE, hence they run (mostly) full speed on the NTR/TWL hardware as HLE is basically doing what the chip does abstracted in High Level and then compiled as native ARM code.

Thank you for being able to explain in detail, And yes, with the information you told me, I understand that it would not be praiseworthy to do so, even though as a user of an NDSi I dream of one day being able to see it with my eyes.

Nope. Nothing like that. it'd have to be both a SuperFX HLE C core (no processor context whatsoever) ported to ARM assembly in TWL mode and it'd work on TWL units (Super FX1 & 2).

Otherwise it'd be SuperFX HLE core in C for SuperFX 1 only.

At least reading your response comforts me, now there is only so much I have to learn to be able to support the community to achieve something like this

Another important question, will there be a build where all the roms run with extended memory? (TWL MODE)

As for people unsatisfied with a bit of the issues that ver 0.6d developed just use the version 0.6c that Coto updated that comes with Twilight Menu ++ it is more stable and still has alot of the updates he has put in until 0.6d. He ended up doing alot of work on the emulator but since does not want to waste his time as he has moved onto other projects.

https://github.com/DS-Homebrew/TWiLightMenu/releases

Download the TWiLightMenu-Flashcard.7z one and use /_nds/TWiLightMenu/emulators/SNEmulDS.nds from the zip file.

Gets rid of the occasional stuttering 0.6d has that problem. And still is pretty optimised compared to 0.6a legacy.

EDIT:
And also for DSi users, until Coto finihses polishing up the little issues compared to 0.6c maybe as he has updated a bit in his spare time just use the New snes emu 0.6c that comes with Twilight Menu ++ to launch SNES .smc files/games directly from Twilight Menu ++.

Set this line in your config: in root:/_nds/TWiLightMenu/settings.ini

Under [SRLOADER] add a line -

Code:

NEW_SNES_EMU_VER = 1

I know there has been alot of talk about this so maybe you might be satisfied with 0.6c

i'm glad to see there is still someone working on this emulator. I edited my first post added the bitbucket link.
Thanks Coto

Hello anyway you guys port it this on psp?

nitrozz · May 4, 2024

@coto88 it's possible to add reboot/exit game on menu to go back to twl

There are already better SNES emulators on PSP...

Just passing by to say hello and that everything is working well at least for me since last September 2023, didn't updated my SNEmulDS version since this time, but still playing well MegaMan X2 and other versions like the playable zero on X2 and Zero Project on X3. By the way the password on the attached picture is from MegaMan X2: Playable Zero who lead you to leg & arm capsules, one heart tank & wheel gator already defeated. Again thanks coto for not letting the SNEmulDS die once for all. Hope y'all have a great time! Greetings.

Hi guys, so, I have a weird problem... I got this running before on my R4ISDHC card, and booted so0me games just fine, but am now getting this error when trying to run the chainloader:

ARM9: User Exception. TGDS boot fail: Stage [6], firmware model: [0x0] TGDS ARM9 Payload: [NTR] mode ToolchainGenericDS App: abort();

Aside from maybe renaming the .nds files, I'm not sure what I could have done. It was working just fine, but now just this blue screen. What is even weirder to me is that in my process of shuffling the files around between folders I did get a different black screen with yellow font declaring it needed the config.txt file for the chain loader in root.. So I copied it to root, tried again to launch but Ive been getting blue screens ever since. Cannot recreate where it asked for the config at all... Can anyone tell what I might have screwed up here?? This is on a DS Lite with flashcard.

EDIT: Since I can't remember the exact configuration that worked for me, can somebody confirm exactly where they have their files on their cards? If I can start there maybe I can narrow down what else might be going on

EDIT2: Nvm, I got it working again.. Im not sure what I did but I think I may have mixed up a TWL loader with the NTR one? Maybe when I was trying to install it to the DSi as well.. Anyways. Alls well that ends well!

Has anyone gotten Donkey Kong Country to run with 0.6c ntr? It runs near perfectly, minus some small graphical glitches in 0.6c twl, so I wonder why not in ntr; I thought they hadn't made use of the extra DSi memory at this point? Maybe I'm wrong. I feel like it should be able to run though... I can run it in 0.6d ntr, but it has hiccups here and there that are somewhat annoying, which I understand 0.6c generally has less stuttering.. is 0.6d that much more advanced than 0.6c that only it can run DKC?
