Hi, I have made Basilisk II available on Flathub, which makes it easily available on most current Linux distributions. It is available for x86_64 and aarch64.
The current release is pretty much straight from the cebix github repo with some 64bit fixes. The next release will merge in the kanjitalk755 repo and i am looking to have JIT working. (Flatpak's security model is preventing JIT from operating so that requires some non-trivial work)
