Arch Linux User Repository

Good news everyone: the X16 team upstream just announced they have a preliminary agreement with Cloanto, which means they don't have to rewrite the KERNAL (aka x16-rom) from scratch, and the repos are officially back online! So I'm going to revert the PKGBUILDs as they were before real soon.

Give a huge thanks to Perifractic who made this possible (you can find him on YouTube), and vote for the packages if you like them :)

@jsand Thanks for the heads up!

I’ve been able to reproduce the error message.
Turns out that the upstream developers fixed that issue in the latest stable release, r42.

Not working under C23:

You have to use llvm and clang instead. Fixed PKGBUILD:

Yeah, if you want money, either you license it for a good price or you sue. It's possible they thought the project is never going to get off the ground so they didn't bother with that, after all Cloanto is known for keeping their stuff for themselves. In recent days you had The C64 Mini and I think that's pretty much it. But The 8-Bit Guy has 1 million subs on YouTube, the Facebook group for this project has 16K members as I write this, and they already have a working prototype, I'm pretty sure it's going to sell well.

Anyway, I just wish the X16 team the best.

Yes, The 8-Bit Guy announced on the Facebook group he unfortunately removed the repositories for the emulator and the ROM until he rewrote the ROM.

This explains a lot. Thank you for clearing that up.

The "radio silence" of Cloanto regarding licensing requests for the C64 ROM has been nothing but strange. You'd think Cloanto would want to make money from licensing fees. I just don't understand it.

Yes, The 8-Bit Guy announced on the Facebook group he unfortunately removed the repositories for the emulator and the ROM until he rewrote the ROM. I posted on the forums about it, this is out of copyright concerns, it contained modified code from the original Commodore 64 and he was unable to contact Cloanto (the current copyright holder) about licensing it.

However, it does look like Michael Steil (whom I know is the main developer) has reposted the repositories on his personal account, so I guess I'm going to update the PKGBUILDs to those easily. Thanks for the tip!

EDIT: Done :) However, the tags are gone and he still haven't retagged r36 on the x16-rom repo. I changed it, but it's not gonna work until he has done so and I'm going to check this with him.

It looks like the <https://github.com/commanderx16> github account no longer hosts the the Commander x16 emulator source code or the source code for its ROM. These repositories have been migrated to <https://github.com/mist64> instead. As a result, the PKGBUILD isn't going to work anymore until it is updated to point to the new repository.

The documentation and demo code is still hosted at <https://github.com/commanderx16>, so my hunch is that the repository owners are merely separating concerns.
