i guess for people that wanna use retroarch like launchbox to get their emulators all in one app
According to forum, there is mention of āunofficial coresā but no specific list of all of them is mentioned in the search results. The mentioned GitHub repository, https://github.com/SwedishGojira/libretro-bash-launcher/, is a specific example of one of these unofficial cores.
i think this is a good place to post it , and we donĀ“t derail a thread for it if we discuss this here^^
i going to test it today

Hi!
Iām new to the libretro community and I was wondering if there is a formal process/document outlining how to submit a new core?
The reason Iās asking is because I have just created a core for my IBM 5150/5160 emulator. Core builds can be downloaded here and source code is on GitHub.
It would be cool if I could make it easier for people to find and use.

oh, thatās awesome!
To get it into the online updater, we need it to have a recipe to build on our CI infrastructure in the top-level of the source tree and a core info file submitted to the ālibretro-superā repo on github.
Are you on discord? If so, the user BoardsOfCanada on there can probably help you get the CI stuff squared away. For the core info stuff Iām happy to help with, but you can pretty much just go down the line with this annotated skeleton and fill in what applies: https://github.com/libretro/libretro-super/blob/master/dist/info/00_example_libretro.info

I had to boot off of a PC-DOS disk, swap disks, and manually run the executable. But I managed it with my first try.
Nice work @phix !!!
It will be nice to have a dedicated core to go along with my 5150 Presets.

so i was wondering if is kinda like dosbox or not but seems this just emulates the hardwareā¦
hmmm then i have to visit my dad and get the old pc-booter games that donĀ“t need dos

I think I still have the discs for Starflight around here somewhere. I think it ran straight from the discs. Canāt remember.
besides pc.man i donĀ“t know wich other pc-booter games i had a few thats sure , just know that everything is still safe by my dad in the basement
Hi, thanks!
Iāll reach out in Discord then. 
I do have a .info file here that I created. I donāt think RetroArch is happy without one? Had problems loading content without it.

There is also support for running and executing files directly from your host systems disk. But it is not included in the core. I felt like the disc swapping system is more tailored towards consoles like the Playstation etc. (make sense I guess 
)
I thought of supporting ZIP files as a compliment to the raw IMG files in the core instead of mounting a host folder like the standalone emulator does. That could perhaps work better with the Libretro way of handling ādiscsā.
It would work something like the setup I have on this site.
If the zip file could contain extracted floppy contents, compatibility would be greatly improved. I am having a tough time curating a solid set of contents. Seems disk size is really important in the RAW images.
Also. Does the standalone support multiple floppy drives? Many games require a B: drive for user data.
The standalone emulator comes with a default freedos harddrive for ease of use. So you have your A: drive free, as well as Z: mapped (read only by default) to your working directory or a path specified with the --rifs parameter.
Technically the emulator supports multiple drives. But Iām not sure if the B: drive is exposed in the UI at this point. I was not aware of any software requiring two drives? (I will create an issue for adding support in the UI.)
For the libretro core it is a little harder though, since I donāt think there is a concept of multiple drives.

Yeah, maybe not in the UI, I donāt know. MAME and DOSBox both support multiple floppies from the command line or config file. (dosbox.conf)
This sounds very convenient, and would probably negate the need for a B: drive.
From what I remember, it was never ārequiredā only more convenient. I only asked because it came up in my testing in the last 24 hours. (Bardās Tale 1)
BTW. I never loved a HDD More than my first WD 20MB MFM.

I did not read the last line of your post properly! When I glanced at your post earlier I just thought that was a picture of your real machine. Looks amazing!
This is one of the reasons I want to support a libretro core for my emulator.

Thank you!
In case you have never seen the night version.
Sure is great not to have to mess with DOSBox configs to get a CGA display!
Although Iām not 100% sure the IBM 5153 monitor supported CGA. 
I may have to do some research and add another version to my graphics pack.
Edit: The 5153 was a CGA display. The 5154 was EGA and had different colored knobs and additional text on the badge.
Looks like I have a small project in the near future. The VGA 5175 was indistinguishable (Except for more badge changes.) so the graphic will be a 2 for 1.
Thanks for the inspiration!

You should do the 5151 monochrome one for MDA as well.

The 5151 is already included in my pack.
In this case the shader forces a monochrome hue that can be adjusted with parameters.
When I finish my update we will have MDA, CGA, EGA, and VGA.

Why donāt these people include those cores directly in RetroArch?
You handle textures very well, you have to try that in 3D.
Dunno
