Homebrew Unofficial 3DS RetroArch builds

Is anybody planning on porting the Commodore emulator VICE to the 3DS? At least the C64 part of it would be awesome. The existing Frodo port "Breadbox" that we have is OK but many games don't work properly. If there is a Atari 8-bit emulator that works well, there should be an equally good C64 emulator I think :)
And VICE is already part of the Retroarch system... just not on the 3DS.

Hmm.. it seems libretro VICE is available on just about every other platform..
If i would be able to build a libretro core of VICE for 3ds, it wouldn't include any 3ds specific enhancements.
I personally don't have any experience with VICE vs. FRODO. Does it have higher compatibility or other advantages on other platforms?

Last time i checked there wasn't a universal virtual keyboard driver for 3ds available in libretro.
In my opinion, this should have first priority.

This should improve overall usability, and enables the usage of cores like VICE.

I really do think a virtual keyboard is important, but if we can manage to get pcsx-rearmed to build with unai on the 3DS that would be great.

The 3DS Frodo port BreadBox has a virtual keyboard on the lower screen. A C64 emulator without a keyboard is almost useless. The keyboard is needed all the time. So yeah, the VICE port must have that as well. I think the two screens on the 3DS are just perfect for C64 emulation. On other platforms, unless you have a real keyboard connected, you always need to interrupt the action by popping up a virtual keyboard. Not needed on the 3DS.

I know it's not what you've been waiting for.. but here's an updated 1.7.5 version of O2EM. Since it's been able to start more than 2 games now. And i actually like the videopac.. :yay:
Key's 1-4 are set in the emulator to Y X L R. Use those to start a game, if required.
Other keyboard keys are not supported, only joystick support. So only joystick supported games.

Place 'o2em_libretro.3dsx' in: 'sdmc:/retroarch/cores/'.
*requires bios, see here

Isn't pcsx-rearmed already being build with unai?

Haven't looked into it otherwise..

At least some other libretro emulators have some sort of virtual keyboard solution buildin. It's not ideal for retroarch, but if and until another solution is created.. it's all we got.
Are you aware of a virtual keyboard already being available in VICE on other platforms?

There are some other things which needs to be adressed first, before i'll even look into VICE.
Libretro currently requires an older revision of ctrulib, getting it up to date and update the builds provided in this thread have priority for now.. then maybe look into some of the other issues and cores.

For now, enjoy an up-to-date O2EM :creep:

It appears that Vice for Retropie has a virtual keyboard, that can be activated by pressing a button on the controller. Not sure how it works exactly, or how it looks like. Can't find screenshots, and I don't have a retropie (Raspberry Pie) setup.
Google "Navigating lr-vice gui"
Also, on the main sourceforge page there is a feature request for VICE getting a native virtual keyboard built in, but the developers declare it difficult
Google "#294 Virtual Keyboard in VICE"

Here's a new 1.7.7 build. Drop the .cia and/or .3dsx in sdmc:/retroarch/cores/ and launch your compressed fba roms with it.
Still runs at about 40fps in-game.

Intro


Unofficial 3DS RetroArch Builds
RetroArch 1.4.0+.​


The RetroArch Team did a wonderfull job on bringing us a 3DS version of their project.
Seeing how development on the 3DS version of RetroArch has slowed down nowadays,
i thought it would be best to just get the most out of what we've got up until today.

In this thread you will be provided with Libretro 'cores' which the RetroArch Team doesn't compile themselves for the 3DS.

[B]matt![/B] has created some genuine looking artwork for these builds, Special thanks to matt!
And of course, credits to the RetroArch team!

Initial Setup



Download the latest STABLE or NIGHTLY build from the Libretro Buildbot:
https://buildbot.libretro.com/

Stable Builds (1.6.9 )
Nightly Builds

.3dsx installation
  1. Extract retroarch_3dsx.7z
  2. Copy 'retroarch' folder to root of your SD; 'SD:/'
  3. Copy the folders including cores you want to use to: 'SD:/3ds/'


.cia installation (recommended)
  1. Extract retroarch_cia.7z
  2. Copy 'retroarch' folder to root of your SD; 'SD:/'
  3. Install all the .cia's (cores) you want to use, using your preferred method. (like FBI)
  4. (optional) Install the 'retroarch_3ds.cia', using your preferred method. (like FBI)


The 'retroarch_3ds.cia'
This is the RetroArch frontend compiled without a core.
It is used to launch the last loaded core.

To use this you need to have at least one 1.4.X+ .cia core installed.
Before launching the 'retroarch_3ds.cia', you'll need to:
  • Launch a separate core first
  • Load a game
  • Exit trough the menu
This will allow RetroArch to create a .cfg and set the last loaded core.

AvgiMPV.png
WGKr2IB.png

unofficial builds don't have icons yet

If you get the 'SD has been removed' message, it tries to load a NON-installed core.
Repeat the above steps. If you have used retroarch before (pre-1.4.X), read THIS.


^back^



Update RetroArch



When upgrading from a pre-1.4.0 version of RetroArch, it is important to start with clean configuration files.
Make sure you replace the 'SD:/retroarch/' folder.

Update 1.3.X
  • Backup / rename your old 'retroarch' folder; 'SD:/retroarch/'
  • Delete / rename your old 'retroarch' folder
  • Follow the Setup again, upgrading all cores
  • Optional: Restore savefiles from backup

Update 1.4.X+
  • Follow the Setup again, upgrading all cores. No need to replace the 'SD:/retroarch/' folder.

'rgui' / 'xmb' / 'xmb' theme

The release of 1.4.0 added support for XMB menu.

You can switch between the old 'rgui' and the new 'xmb'

You can change the 'Menu Color Theme' and the 'Menu Icon Theme' to suit your liking.
- Settings / User Interface / Menu /

*restart is required to load changes

FAQ



General:

Q) I still have the 'old' green GUI (RGUI) / theme. How do i change it?
A) Change 'Menu Driver'. See: RetroArch Themes *'RGUI' is recommended!

Q) How do i Disable / Edit the yellow console messages on the top screen?
A) Settings / Onscreen Display / Onscreen Notifications / Enable Onscreen Notifications

Q) CORE switch doesn't work, game loads with the current (wrong) core.
A) Try to remove CORE overrides: SD:/retroarch/config/*CORE/*CORE.cfg

Q) All cores are really slow on my New3DS (comparing to game compatibility lists).
A) Check if you've got 804mhz, L2 Cache enabled, using NTR or similar. (RetroArch should set this by itself)

Q) Your download contains a VIRUS!!
A) Some antivirus software may detect some 'suspicious' code inside the builds i provide.

This is called a 'false positive', the code is taken straight from Libretro's git.
Minimal changes are made to fix errors and compile 3DS builds.

Core Specific:

Q) Do CPS3 games run on my old3DS?
A) No, only on New3DS

As it turns out, Bada created a highly customized 3DS build of the VICE emulator for Commodore 64
https://gbatemp.net/threads/release-vice3ds-c64-emulator.534830/
The first public release was on March 30, and by now we have a practically finished product. So it took something like 4 months. This is not under Retroarch. It makes me question the whole idea of Retroarch. Can it deliver the best results? I'm pretty sure that an "official" retroarch port of VICE would never be as awesome as VICE 3DS. Vice 3DS is now the best portable C64 emulator, across all platforms.
