Batocera runs on x86_64 mini-PCs, on the Raspberry Pi and on the ARM
handhelds alike. A cartridge is data for an emulator and runs anywhere,
which is why this store has been portable so far — but a native build
only starts on the architecture it was built for, and an x86_64 binary
installed on a Pi is worse than one never offered.
`kind` and `ext` may now be a map from architecture to value, with `*`
as a fallback; a plain string still means "the same everywhere", so
existing configs are untouched. The detected architecture is reported at
the top of `list` and as `detected_arch` in `config`, and a title with no
asset for the running machine is skipped with a reason that names it.
Verified on aarch64 against the live catalog: the cartridge config
behaves exactly as before, a bevy entry mapped per architecture pulls
bevydemo-1.0.0-linux-arm64.zip, and the binary inside is an AArch64 ELF.
A map without an entry for the machine skips and says so.
