RetroArch bk Core: Elektronika BK-0010/BK-0011(M) Reference

The bk core is a port of a PDP11 emulator to libretro that runs in RetroArch. According to the official libretro documentation, it emulates the Soviet Elektronika BK computer series and also the Terak 8510/a, a 1976 American PDP-11/03 platform of which the Elektronika BK series are clones.

Emulated Systems

The official description lists three Elektronika BK machines — the BK-0010, the BK-0010.01 and the BK-0011(M) — alongside the Terak 8510/a. The BK series are described as clones of the Terak 8510/a PDP-11/03 platform, which ties the whole core to a single PDP-11 lineage.

Documented Feature Support

The official documentation includes a feature-support table for the core, and the entries in the table below reflect it. Five features are marked as supported: Screenshots, Rewind, Core Options, Controls and Remapping.

Several other capabilities are marked as not supported, including Restart, Saves, States, Netplay, Multi-Mouse, Rumble, Sensors, Camera, Location, Subsystem, Softpatching, Disk Control, Username, Language, Crop Overscan and LEDs.

What This Means for Use

Because Saves, States, Netplay and Disk Control are documented as not supported, plan around those limitations. Rewind, Screenshots, Core Options, Controls and Remapping are documented as available, so basic input configuration, per-core options, snapshots and rewind are the primary areas the source identifies as configurable.

The official documentation description notes that the page covers BIOS files, core options and controls for the bk core. Consult that page for exact BIOS filenames and current option wording, since this summary does not reproduce those file-level details.
