OpenMSX flatpak

Thanks for the explanations. I've followed your guides and it worked.

Now I have to version, a native version compiled thanks to Manuel and the flatpak version. Great!

Yeah, that should be quite easy if a development branch will be distributed via flatpak.

You mean for Windows right? (I believe Flatpaks can be made portable (create-usb), otherwise AppImage.)

I think that should be possible with PortableApps.com Launcher

It's already possible to run openMSX in a portable way with the aid of a .bat file (has been discussed here (not too long ago) & in openMSX's issue tracker). Catapult uses the registry though. That's where PA Launcher would come in.

For Linux, in addition to flatpak, there is snap and appimage that allow you to create a package that works on multiple distributions. But I have never created a snap or appimage package before. And you can install flatpak on pretty much every distribution, so I don't see a real need to create a snap or appimage package.

And as mentioned, you can make a flatpak somewhat portable with create-usb if you want to carry it around.
