+# Playdia (PlaydiaEmu)
+
+## Background
+
+The Playdia is a Japanese interactive CD console released by Bandai in 1994. Titles are largely full-motion video driven by a CDS-XA disc stream, with video and audio decoded on a dedicated co-processor board and interactive choices advancing the stream. PlaydiaEmu is an emulator for this platform written in Rust, with a libretro core front-end.
+
+The PlaydiaEmu core has been authored by:
+
+- Aloys
+
+The PlaydiaEmu core is licensed under:
+
+- [BSD-3-Clause](https://github.com/AloysHF/PlaydiaEmu/blob/master/LICENSE)
+
+A summary of the licenses behind RetroArch and its cores can be found [here](../development/licenses.md).
+
+## BIOS
+
+No BIOS or firmware files are required. The libretro core uses the same HLE disc player as the standalone emulator.
+
+## Extensions
+
+Content that can be loaded by the PlaydiaEmu core have the following file extensions:
+
+- .cue
+- .zip
+- .iso
+- .bin
+
+Redump-style `.zip` archives (CUE + BIN, or a single BIN/ISO) are opened by the core itself; RetroArch should pass the whole archive through (`block_extract`).
