Snes9x for Old 3DS / 2DS Version 1.30 Released (24 Mar 2018)

Snes9x for 3DS is an SNES emulator for your old 3DS / 2DS. It runs many games at full speed (60 fps). It supports games that use CX4 chip (Megaman X2/X3), the SDD-1 chip (Star Ocean, Super Street Fighter 2 Alpha), DSP chip (Super Mario Kart). It also runs games that use the SA-1 chip (Super Mario RPG, Kirby's Dreamland), SuperFX chip (Yoshi's Island, Star Fox etc) but these games run with plenty of frame drops. It has a much high compatibility than existing SNES emulators on the 3DS because it uses Snes9x 1.43 as a base, and is a good alternative if your existing emulators cannot play all the games.

It also runs better on the New 3DS. Games that slow on the Old 3DS will benefit from the higher clock speed that the New 3DS offers! (In some New 3DS set ups you may have to manually force the clock speed up to enjoy the performance boost)

Download From Github:
https://github.com/bubble2k16/snes9x_3ds/releases/download/v1.30/snes9x_3ds-v1.30.zip

3dsx version:
1. Copy the Snes9x_3ds.smdh, Snes9x_3ds.3dsx, Snes9x_3ds.smdh and snes9x_3ds_top.png into any folder on your SD card. (Both files must be in the same folder)
2. Place your SNES ROMs into your SD card into any folder (for v0.3 and above)
3. Go to your Homebrew Launcher and launch the snes9x_3ds.3dsx emulator.

CIA version:
1. Use your favorite CIA installer to install snes9x_3ds.cia into your CFW.
2. Place your SNES ROMs inside any folder.
3. Copy snes9x_3ds_top.png to ROOT of your SD card.
4. Exit your CIA installer and go to your CFW's home screen to launch the app.

Inside the Emulator:
1. Tap the bottom screen for the menu.
2. Use Up/Down to choose option, and A to confirm.
3. Use Left/Right to change between ROM selection and emulator options.
4. You can quit the emulator to your homebrew launcher / your CFW's home screen.

Feedback and bug reports are welcome. Help with development is also welcome!

Features:

1. Graphic modes 0 - 7.
2. Save states of up to 4 slots.
3. Uses CSND for audio.
4. Frame skipping
5. Full screen
6. SDD1 chip (Star Ocean, Super Street Fighter 2 Alpha works)
7. DSP-1 (Pilotwings works well / Super Mario Kart / Ace o Nerae)
8. CX4 (Megaman X2/X3 runs well)
9. SA-1 (Super Mario RPG, Kirby Dreamland: slow on old 3DS. runs well on new 3DS)
10. SuperFX (Yoshi's Island: slow on old 3DS. runs well on new 3DS)
11. Runs faster on new 3DS.

Not Available / Problematic:

1. Minor sound issues.
2. Mosaic effect and mid-frame palette update problems - we use the 3DS hardware for speed; but we have to give up these two features for it. Most games work well without it. If you game's colours look funny, go to the Settings and try changing the palette options.
3. Resume from sleep mode

Can confirm this is the real deal. Not had the chance to test on my O3DS yet, but works nicely on my N3DS - Mario World runs at 60fps, bar small hiccups when loading data. Impressive stuff.

What version of Snes9x is this based on?

I think there is a layering problem, Playing SMB3 On super mario allstars +Super mario world and the items inside of objects can still be seen on screen and look like it passes through rather come out of or go inside. Mushrooms come out of blogs and you can see all of the mushroom before it fully out. Same for prianna plants.

Sound is a known problem so i won't say anything about it.

There some slow downs when selecting stages :P

sj33, this is based on v1.43. The versions after v1.51 are too slow.

I didn't know that 1.51 wasn't fast, i use always the latest versions on my console emulators like wii and Android 1.53 but i never had any slowdown problems. :unsure:

Unless he mis-spoke...

"So I had the idea of using blargSNES as a Virtual Console emulator, as it's the only one that's known to run at full speed speed on the old 3ds."
As a virtual console emulator, a way to play snes roms on the old 3ds since only new 3ds are supported by offical VC.

Well, I'm assuming you are using a recent Android phone. It should be fast enough to run the latest versions of Snes9x without problems. But on the old 3DS, it's an entirely different story. :)

Oh, and er... I'll try to look into the glitchy borders problem. Doesn't happen on mine though.

Can always add cheats later on too. :) It was always there in Snes9x... now I just need the time to hook it up...
