Puzzle3DS​ is a simple memory game for the 3DS by trainboy2019. All you have to do is memorize the pattern shown on the bottom, then when the indicator in the top left is green, repeat the pattern.

Release notes:

Made the patterns more random. Thanks, @MaiconErick

Snes9x for 3DS is a high-compatibility 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), and the SDD-1 chip (Star Ocean, Super Street Fighter 2 Alpha). It can also play games that use the SuperFX chip (Yoshi’s Island, etc), and the SA-1 chip (Super Mario RPG, Kirby’s Dreamland, Kirby Super Star) but it runs slowly. It generally supports higher compatibility than existing SNES emulators on the old 3DS, because it uses Snes9x 1.43 as a base, and is a good alternative if your existing emulators cannot play all games. It also runs on your New 3DS, and performs much faster! Use your New 3DS if you want to play SuperFX and SA-1 games!

Changes:

* Added BlargSNES DSP Core (experimental) for performance. The original Snes9X DSP core (default) suffers from sound skipping in some games. You can choose which DSP core to use from the Options menu.
* Added support for Tengai Makyou Zero English Patch (for hopefully all future versions)

Norix‘s NES/Famicom emulator VirtuaNES has been ported to the Nintendo 3DS by bubble2k16.

It used to be considered one of the best emulators before FCE and Nestopia, and it runs quite fast for lower spec-ed computers (at the cost of some emulation accuracy). But because of that, the Old 3DS / 2DS is able to benefit from this fast running emulator core. This runs full speed on an old 3DS / 2DS with support for tonnes of mappers. Although it doesn’t support every single mapper, the library of games that can run on this are probably fairly huge already.

Thanks to Nintendomax for the hint!

PicoDrive for 3DS is a port of notaz’s PicoDrive emulator by bubble2k16 to the old 3DS / 2DS. Although PicoDrive is already highly optimized for ARM processors, if ported as is, it still doesn’t run full speed for all Mega Drive games on the old 3DS / 2DS, as it’s evident in the RetroArch’s version. So this port heavily relies on the 3DS’s 2nd core to emulate the FM synthesized music for the YM2612 FM chip to achieve 60 FPS. But the 2nd core on the old 3DS is unfortunately not fast enough to generate the FM synthesized music at a full 44100Hz, so sounds are generated at 30000Hz on an Old 3DS. It sounds ok for many games, except for those that use high-pitched notes or sound samples. The screen rendering is done completely using the original PicoDrive’s ARM processor-optimized renderer.

You can play Master System, Mega Drive games and Sega CD games, and 32X games. CD games run a little slower (you should enable 1-2 frameskips) on an old 3DS, but it runs very well on a new 3DS. 32X games can only played at a reasonable speed on a New 3DS using the .CIA version of the emulator. Some dynarec instructions for 32X games will crash the emulator (Virtual Fighter, Virtual Racing Deluxe have this issue).

Release notes:

I’m putting up v0.94b for testing for anyone who would like the latest. 🙂

Fixes include:
– Added support to save battery-backed RAM for CD games
– Fixed problems with games that show parts of the previous screens at the left/right edges
– Added support for cheats.

No emulation-related fixes, so in terms of compatibility, it should remain the same as v0.93.

Some explanation on the cheat format:

The .CHX is a cheat file format that you can create with any text editor. Each line in the file corresponds to one cheat, and is of the following format:

[Y/N],[CheatCode],[Name]

1. [Y/N] represents whether the cheat is enabled. Whenever you enable/disable it in the emulator, the .CHX cheat file will be modified to save your changes.
2. [CheatCode] must be an Genesis / Mega Drive Game Genie or Pro Action Replay cheat code. The cheat code looks like one of the following:
– **RHVA-A6WR** (Game Genie)
– **FFFE0D:0099** (Pro Action Replay)
– **FFB933:00** (Pro Action Replay)
– **FFB9 3300** (Pro Action Replay)
3. [Name] is a short name that represents this cheat. Since this will appear in the emulator, keep it short (< 30 characters).

The .CHX must have the same name as your ROM. This is an example of a .CHX file:

Filename: **Contra – Hard Corps (USA).chx**
“`
N,RHVA-A6WR,Invincible
N,NNCT-AAH4,Start with 99 lives
N,H9GA-AAE6,Start with all weapons
N,AM4A-AA8C,You don’t lose a weapon when you die
“`

NOTE: Some games may not boot when cheat codes are enabled at the start. Disable the cheat codes when booting the games, and enable them only after the game has started.

bubble2k16 updated Exophase‘s TemperPCE for the Nintendo 3DS. It’s a TurboGrafx / PC-Engine emulator to the old 3DS and old 2DS. This port heavily relies on the 3DS’s 3D GPU hardware to achieve 60 FPS (or close to 60 with frame skips).

Release notes:

Hey people, just a very small release (v1.02) to fix the sound lag problem.

Thanks to Nintendomax for the news.

Amy Zing and the Amazing Mazes is little maze solving game by Ant512. The game is loosely based on the snail maze built into some revisions of the Sega Master System BIOS but it isn’t a remake. Like the snail maze, the objective is to guide the red square through the maze from the starting point to the finishing point.

FBI is an open source file and title manager by Steveice10 for the Nintendo 3DS. Discussion via GBAtemp.

Release notes:

* Clean up various bits of core code.
* Fix font size on CHN/KOR/TWN devices.
* HTTP operations now support gzip/deflate compression, which should reduce bandwidth usage when supported by the server.
* Load file metadata after populating full list. Directories containing a lot of CIAs should populate faster now, although detailed information will not be immediately available for all files until loading has finished.
– File operations for which file metadata is unnecessary should also load faster.
* Modify built-in updater to pull from TitleDB, as GitHub no longer supports TLS versions supported by the 3DS.
* Rewrite TitleDB support.
– Titles can be installed as a 3DSX and/or a CIA, depending on availability.
— Descriptions and categories are displayed in the main TitleDB list, and detailed information is displayed for CIA and 3DSX versions after selecting a title.
– Entries will be blue when a newer version is available. Note that all installed titles will be marked as outdated until installed with version 2.5.0 or later through TitleDB, as the last installed version must be added to the cache.
* All outdated titles can be updated at once by pressing Y in the TitleDB list.
– Basic sorting and filtering options have been added.

A lot of internal changes were made leading up to this release. Make sure to report any glitches and crashes that may have been missed.

Also, the built-in updater should no longer work on versions older than 2.5.0, as GitHub has disabled TLSv1.1 support.
