docs: list knulli, amberelec and emuelec

The download page drops a row whose platform has no pack in the
recorded release instead of linking a release that lacks it.

+### KNULLI, AmberELEC and EmuELEC verification
+
+**Source**: `knulli-systems` (KNULLI) and `batocera-systems` (AmberELEC,
+EmuELEC), function `checkBios`
+
+All three keep Batocera's `systems` dict and its checker, run by their
+EmulationStation's BIOS screen.
+
+- **KNULLI** runs Batocera's `checkBios` on files under `/userdata`: `md5sum()`,
+  `checkInsideZip()` for `zippedFile` entries, and the `emulator`/`core` gates
+  read from `es_systems.cfg`.
+- **AmberELEC** runs the same checker on files under `/storage/roms`. Its list
+  sets no gate, and names `neogeo/neogeo.zip` and `neogeo/aes.zip` beside
+  `bios/`, so the pack extracts into `/storage/roms`.
+- **EmuELEC** hashes the whole file under `/storage/roms` and never reads
+  `zippedFile`: an entry that names a member inside an archive compares the
+  archive's MD5 with the member's and reports `UNTESTED` whatever the archive
+  holds. Its list also names game data under `ports/`.
+
+A key written twice in the dict (`naomi` and `Dinothawr` in EmuELEC, `msx1`
+and `msx2+` in KNULLI) keeps its later value, as when Python runs the script.
