Core Updates Summary and more Switch updates - October 2018 - RetroArch Switch NSP, Mupen64plus Switch (experimental), Mr. Boom, Game & Watch, Reicast improvements for PC/Android/ARM, Dosbox SVN for Windows/Linux/Android 32bit, and more!
🕑 Added 2018-10-05 01:57:06 +0000 UTCRetroArch Switch NSP
We now provide an NSP file for Switch straight from our Download page. The main reasons for using this are:
- Being able to launch RetroArch straight from the main menu instead of having to boot Hbmenu first.
- The Mupen64plus core requires more memory to be allocated than Hbmenu currently allows for. Mupen64plus will only work through the NSP file.
You can grab this from our Downloads page here.

New Switch cores!
Just a few days after launch, we already have a few new cores for the Nintendo Switch available for Nintendo Switch! You can grab these new cores by going to ‘Online Updater’ -> ‘Update Cores’ from within RetroArch, and downloading them one by one. Let’s quickly run through some of them:
Mupen64plus
This is an early port of Mupen64 Plus for the libnx Switch port! Please be aware of the following:
- You will need to install RetroArch NSP and boot it straight from the main menu in order to be able to use this core. Mupen64plus requires more memory to be allocated than Hbmenu allows for.
- The framerate right now is not great. This is as a result of there being no dynamic recompiler right now, it just uses a cached interpreter core instead.
NOTE: Everybody is completely aware of the lacking performance of the current Mupen64plus. This is simply a proof of concept for now. Remember, once this bounty (which has amassed so far an amazing $1K+ in little over a week) is finally completed, most games will be running at fullspeed effortlessly on Switch with this emulator!
What this core illustrates is that libretro GL works fine on RetroArch Switch. You can expect to see more libretro GL cores being ported over to Switch in the near future. We are excited for what the future holds over this!
Mr. Boom
This is a great homebrew Bomberman clone made by Javanaise. Up to 8 players can play locally, and you can even setup AI bots that will play against you in either singleplayer mode or multiplayer mode. This should be a perfect fit for the Switch with one Joy Con doubling as two controllers.
GW – Game & Watch
This is a Game & Watch simulator. It runs simulators converted from source code for the games available at MADrigal. Each simulator is converted with pas2lua, which was written specifically for this purpose, and uses bstree, which was also specifically written to obfuscate the generated Lua source code as per MADrigal’s request.

81
81 is a port of the EightyOne (a.k.a. THE Sinclair Emulator) to libretro.
EightyOne emulates a number of ZX80, ZX81, clones, and other computers based on the same hardware:
* Sinclair ZX80
* Sinclair ZX81
* Timex TS1000
* Timex TS1500
* Lambda 8300
* Ringo R470
* MicroDigital TK85
* Jupiter ACE
However, 81-libretro only emulates the Sinclair ZX81 with 16Kb RAM for now. Other machines will be added as time permits. Push requests are welcome.
The port correctly loads and runs some many games I have around in the p format. tzx format is also supported.
EightyOne also emulates some ZX Spectrum machines, but those were left out of this core on purpose. For a ZX Spectrum core for libretro, see the Fuse core.

FUSE
This is a ZX Spectrum emulator.

FB Alpha 2012 Neo Geo for Wii – Virtual Memory support!
Wiimpathy has now added Virtual Memory support for the Nintendo Wii! Finally, those bigger Neo Geo ROMs that were previously impossible to load on RetroArch Wii can finally be played with FBAlpha 2012 Neo Geo core!
Here are some notes left behind by Wiimpathy:
It uses the Wii NAND flash as virtual memory. The games also have to be converted/decrypted first to cache files with a PC program called romcnv.
This program is a modified version of romcnv used for MVS2PSP.
Romcnv binaries: http://www.mediafire.com/file/xb783jd9mxhgbos/romcnv_R2.zip
Romcnv Source: http://www.mediafire.com/file/14a55bohl5u1suo/romcnv_src.zip
Note that a few games(SNK Vs Capcom PCB for example) are still too large with this method.
Dosbox SVN – Dynarec on 32bit Windows/Linux and 32bit Android
radius has done extensive work on a new Dosbox libretro core. The dynarec has now been made to work on the following platforms:
- 32bit Windows/Linux versions
- 32bit Android versions
You can now play fairly modernish games like Duke Nukem 3D (from an MS-DOS perspective) on Dosbox at fullspeed!
But there is more! There is even MIDI playback implemented, and netplay works via IPX.
Reicast
Last time we reported on Reicast, we had full keyboard support implemented which was already hot on the heels of full multiplayer online support with zero network configuration. Since then, flyinghead has not been exactly sitting still. An overview of the progress that has been made since:
- Lightgun emulation support (House of the Dead 2 (US and EU), Confidential Mission (EU), and Death Crimson 2 (JP) all confirmed working)
- Various crucial graphics bugs have been fixed on both Android and ARM Linux. FMVs should no longer show a black screen and Soul Calibur’s characters should no longer be black (due to high quality textures not being rendered).
- Threaded rendering mode’s stability has been further increased.
- A bug existed that caused white lines on the top and right side of the screen. Various games exhibitedthis. This has now been fixed.
- Further improved CHD image support.
The next thing flyinghead is planning to do is merging both Reicast and Reicast OIT into one, so that we no longer need to have two separate renderers/cores!

Any chance those 32bit Dosbox dynarec updates will make their way to the ps vita build? Thanks!!
