Request to get a BBC Micro \ Core added to RetroArch
Hi, is it possible to request the addition of a BBC Micro emulator \ core to RetroArch such as Beebem?
I don't think Beebem would be a great fit due to a fairly restrictive license: https://github.com/stardot/beebem/blob/master/COPYING
What about this Emulator? its GPLv3 and it's still being updated, well this year at least. https://github.com/tom-seddon/b2

Thanks @Ploggy, @hizzlekizzle worth a look at this one?
@hizzlekizzle any update on this? Feels criminal we are missing the mighty BBC Micro from Retroarch.
You might try to open an issue upstream requesting first if they will be interested in Libretro port ?
Ok, I made the request.. hopefully they're open to it :P Add to it if you want :) https://github.com/tom-seddon/b2/issues/186

Hiya, another wonderful emulator for the Beeb is b-em, which I believe is GPL2
I have just raised an upstream issue with b-em as well, with the same topic of porting to libretro https://github.com/stardot/b-em/issues/162
The b-em emulator has already been stripped to the essentials, and made to run on the Raspberry Pi Pico by kilog on stardot ( https://www.youtube.com/watch?v=SFlgZitnUpc )
I have no personal preference for b-em or b2, both are wonderful projects, we are so lucky to have them both. I will note that b-em has more contributors in github at the moment, but whichever project is more open to the libretro port would be a good one to go with.
If a developer from either project is willing to look into the libretro port, is there anyone on the libretro side that would be able to find the time to help answer their questions etc? I'm sure it will help them to know that they have your support.
Cheers

We're always happy to answer any questions. The easiest thing to do is come to our discord server and ask in the programming channel.
Hi all, I've raised this in the libretro discord programming channel: https://discord.com/channels/184109094070779904/876520593636335646/907298657848664105 @jeremyrayner @Ploggy

I raised it in the discird programming channel - sadly not much interest @hizzlekizzle
My comment was in response to:

It wasn't intended to imply that anyone in #programming would volunteer to make the port themselves.
You can only ask, if no ones interested there's not much more that can be done. It'll happen eventually I think, just need to wait it out :P
I would love to see this too. Considering the BBC's popularity it's seems like a glaring omission in the current lineup of home computers.
I've just been looking at RecallBox for the new Pi Zero 2 image for the GPi Case and realised that they now have BBC Micro support! https://wiki.recalbox.com/en/emulators/computers/bbc-micro/beebem "This core is under GPL license." so there should be no issue adding it to retro arch now @hizzlekizzle Details of the add are here: https://gitlab.com/recalbox/recalbox/-/issues/1948
I don't think that's correct. Relicensing a codebase is a pretty significant thing, and it requires the approval of everyone who's ever contributed. OTOH, it's very easy to mislabel a license in a large project like RecallBox. This line is particularly troublesome:
- This program must be distributed COMPLETE, with source code. Binary-only distribution is not permitted.
https://github.com/stardot/beebem-windows is the current repo, and it's apparently GPL. The licence changed at some point: https://stardot.org.uk/forums/viewtopic.php?t=2445

@hizzlekizzle would this update change anything based on Tom's response?
It's good we got clarification on the GPl issue, the problem now is someone willing to add it to Retroarch :)
Hi,
I contacted the owner of Beebem who has given permission for its usage: Mike Wyatt [email protected] To: Richard Wadsworth

Hi Rik,
Good to hear from another retro and BBC Micro enthusiast! I'm all for widening the audience for retro projects and BeebEm in particular.
BeebEm has already been used in a number of bundled emulation systems. The issue of licensing does always raise some questions. Back in 2009 I got the agreement from all of the BeebEm authors to switch the licensing of the Windows build to GPL2.
The Linux build of BeebEm though, which a lot of these third party systems use, pre-dates this GPL change, and no-one (to my knowledge) has yet updated the sources to bring them in-line with the latest Windows version. So, licensing for the Linux sources remains as the original author (Dave Gilbert) specified in the COPYING file (attached). Having said that, I'm sure Dave would have no problem with BeebEm being included in an ArkOS build, as long as it was freely available.
More of an issue is licensing for the BBC Micro OS and BASIC ROM images. Although some effort has been made to establish who owns the copyright for these ROMs, it has never been fully resolved. There remains a risk that a commercial entity may at some point object to the use of the ROMs (although no-one has ever contacted me regarding use of them).
The Linux port of BeebEm is available here:
http://beebem-unix.bbcmicro.com/
There may well be some further updates available for the Linux port scattered across the Internet - I've never looked in any detail!
I've not seen recallbox before. It looks like they picked up the Linux port and, even though they have kept their repo private, I doubt they have made any significant modifications to it.
Hope all of this helps. If you do port BeebEm to a new system, I would be happy to add a link to it from my BeebEm site.
Kind regards, Mike

I hope you don't mid the approach. I'm a child of the 80s and grew up with home computing. My favourite systems of all time are the Acorn Electron and BBC Micro. I'm also heavily into emulation and retro gaming, particularly retro handhelds such as the Anbernic RG350M and the RG351M. Where possible I've been championing the use of BBC Micro emulators onto new systems to allow more people to experience the mighty BBC Micro.
I can see that Recalbox have used your emulator in their latest build: https://wiki.recalbox.com/en/emulators/computers/bbc-micro
I'd like to be able to use your code in a couple of the most popular handheld systems: ArkOS and AmberELEC. These are strictly non profit and are done by the love of the community. I've raised this ticket to see if we can get BeebEm added to ArkOS but the lead developer has come back saying it is not publicly available - see below.
Can you let me know if you have any objections and permission to use BeebEm in these retro handhelds to bring the BBC Micro experience to the a wider community?
Many thanks
Rik
Brilliant! but we still have the issue of who is going to add it as a Libretro Core :P

Any ideas?
The only people I can think of are the Retroarch devs themselves, but we've asked them iirc? Don't get me wrong I'm not trying to crap on this I VERY MUCH would like to see this as a Core on RA :) We could ask again on the RA discord, but that could have the opposite effect ;)
Would you raise it on the RA Discord and I'll support it? See how far we can get. We are close: we have a decent emulator and permission to use it, just needs adding in :-)

I saw :) still though, need some kind soul to port it.
I've read its possible to run BBC Micro from within Retroarch's MAME Core? MAME (current) has all the MESS Cores merged into it, one of which is BBC MIcro, so possibly it wouldn't need to be ported into Retroarch since technically its already in there? If that's true could the BBC Micro Core be made into its own Core similar to what SameCDI does with the Philips CDI Core from MAME?
Its along way around I admit but it's possible?
