Homebrew Emulator RetroArch Wii - The Return of the Extra Unofficial Cores

[SaulFabre]

This will be the continuation of @zerofalcon's thread https://gbatemp.net/threads/retroarch-unofficial-extra-cores.405410/

These cores i will mention here are not available within nightly builds, so I compiled and uploaded these for those people who want to test it or like to play with those tiny and classic emulators.
Be aware that some cores won't have so much performance (such Virtual Jaguar), and some cores aren't finished/updated anymore.

All these UNOFFICIAL cores were compiled with RetroArch Wii GUI v1.15.0

Cores I will post here:

• Virtual Jaguar - Atari Jaguar (EXTREMELY slow and unstable, https://github.com/saulfabregwiivc/VirtualJaguar-Libretro-Wii, forked from https://github.com/libretro/virtualjaguar-libretro)
• DOSBox - Microsoft MS-DOS
  You'll have two choices:
  - DOSBox-Libretro (https://github.com/libretro/dosbox-libretro)
  - DOSBox SVN (https://github.com/libretro/dosbox-svn) There's the normal one (dosbox_svn) and an (unstable) version with the PowerPC (PPC) dynarec (dosbox_svn_ppc_dynarec_unstable), in the post #3 below).
• PicoDrive - Sega Master System/Genesis/Mega Drive/Mega CD/Pico/32X/32X CD (General optimization from irixxxx, https://github.com/irixxxx/picodrive, forked from https://github.com/libretro/picodrive) There's the normal one (picodrive) and an (unstable) version with the PowerPC (PPC) dynarec (picodrive_ppc_dynarec_unstable), in the post #3 below).
• MAME 2003 Midway - Midway arcade games (https://github.com/libretro/mame2003_midway)
• A5200-Libretro - Atari 5200 (https://github.com/libretro/a5200) (thanks @ploggy!)
• VisualBoyAdvance-M / VBA-M - Game Boy/Game Boy Color/Game Boy Advance (https://github.com/visualboyadvance-m/visualboyadvance-m). I could have used this one https://github.com/libretro/vbam-libretro but upstream VBA-M is the most updated here, for compile it correctly i used this patch: https://github.com/visualboyadvance-m/visualboyadvance-m/pull/1171 (thanks @ploggy!)
• Genesis Plus GX - Sega Master System/Genesis/Mega Drive/Mega CD/Pico (official eke-eke core since the Libretro one is broken, https://github.com/ekeeke/Genesis-Plus-GX)
• Frodo - Commodore 64 (http://github.com/libretro/frodo-libretro)
• Potator - Watara Supervision, a Game Boy-type clone (https://github.com/libretro/potator) (thanks @ploggy!)
• Hatari - Atari ST/STE/TT/Falcon (https://github.com/libretro/hatari) (thanks @ploggy!)
• NeoCD-Libretro - SNK NeoGeo CD - Downloads and info here https://gbatemp.net/threads/unoffic...core-for-the-wii-powered-by-retroarch.630584/

For get the .info files of the cores for be able to use them, download them at https://github.com/libretro/libretro-core-info

Please test these builds of cores, thanks

[SaulFabre]

Here's some (unstable) builds with PPC dynarec enabled, on DOSBox SVN and PicoDrive.

yes

Hi Saul, long time no talk. Quick question: to the best of your knowledge, has anyone been able to fix the crackling audio in Picodrive with 32x games?

p.s. @SaulFabre Your builds of PicoDrive are identical. picodrive_irixxxx_libretro_wii.dol is a bit perfect copy of picodrive_irixxxx_ppcdynarec_unstable_libretro_wii.dol, or so my computer tells me.

yes

Hi Saul
The info file is not included in your download of picodrive_irixxxx_libretro_wii.dol
Can I just use the picodrive info file from the latest official libretro release?
Thanks

Thanks

yes, u can still use the .info file from Libretro, it will still work fine

Does the midway core support MK romhacks like MK2 plus and UMK3 juggernaut? Also what kind of speed does it get?

Hi @SaulFabre,

thanks for your work.

Since you obviously have the build environment, would it be too much to ask that you also provide genesis_plus_gx_wide_libretro_wii.dol?

Genesis Plus GX Wide it's already officially included on latest RA Wii builds...

 

[JuanMena]

As @SaulFabre said, Gebesis Plus Wide core is indeed included in official RetroArch-Wii releases...

But you won't be able to take advantage of the increased resolution to play widescreen. The Wii isn't capable enough. Just like ir can't use BSNES neither.
Also, little sidenote, RetroArch 1.15.0 won't save configuration even with .config files. So we're stuck with Genesis Plus core which works up to 1.9.0 or Genesis Plus Wide which works in all versions, but again, won't save configuration files.

Yes, you're right. But this one is broken.

I was hoping that you might have a working version or you could, thanks to a working build environment, find out the toxic commit via git bisect.

Here's the Potator Core for Wii This is a Watara SuperVision Emulator, a Gameboy type clone.
This is untested but I compiled the Core for WiiU and it worked fine!

works very well thank you for your excellent work

 

[Maeson]

Very curious, I did not know about this particular system! I will look for information about it.

Oh, and I wonder, did the Virtual Boy core ever got fixed?

 

[MeXen]

works very well thank you for your excellent work

Quick Question, how do you manage to make images on RA work? i NEVER, EVER got any luck, and let alone older versions of RA that had the Image Viewer core that didnt work for shit, also can you finally load PNGs and JPEGs or videos on RA wii? would make some experiments less of a hassle.

That feature of displaying pics is called a Playlist.
You have to manually create a Playlist within RetroArch to get this to work, or at least that's how it works in PC.

Your games must match a database within RetroArch in order to download each picture (Boxart, Screenshots, Titlescreens or Covers) for each game.

Didn't knew that the old Wii could handle this.

If for it to work you must create a playlist for each system, first you create a folder with the name thumbnail in ; sd or usb/retroarch/thumbnails inside the thumbnails folder you put the systems folders. example; sd/retroarch/thumbnails/snes. The snes folder must have the exact same name as the snes folder of the roms. example; sd/roms/snes. now in the snes folder you created inside thumbnails create 3 folders Named_Boxarts, Named_Snaps, Named_Titles, in those folders put the images here with each system then open retroarch go to playlist/import content/manual scancontent directory and select the snes roms folder then select the retroarch core that you want for snes you also select the extension of the rom if it is in zip write zip or snes it depends on the format of your rom and below you give start scan to create the list when you do it it seems that it was not doing anything Just wait 15 seconds and then the snes list will appear, then in retroarch settings you enter setting/user interface/appearance/show playlist thumbnail you put it on and that's it sorry my english I'm using the translator I hope it works for you

A5200 Core, I know this is in the first post, but this Core has been broken (and now fixed) and hopefully added to the Wii buildbot later today

Hey @ploggy, thanks! I could add your updated build to the first post replacing the old broken one.

Question: any chance for see how to fix video on VBA-M core when compiled for Wii? It compiles fine but when I tested any game I loaded it just displayed a white screen.

Sorry I can compile some Cores but when it comes to actually fixing code I haven't got a clue ha ha.
Any reason you want VBA-M to work in particular?
