RetroDECK v0.10.0b is released. RetroDECK brings you an all-in-one sandboxed application to play your retro games (and even not-so-retro games) on Linux/SteamOS.

RetroDECK Changelog:
RetroDECK 0.10.0b is a major milestone release featuring a complete rebuild of the platform. While much of this work happens behind the scenes, it significantly improves maintainability and future expandability.
Important
Ponzu is not compatible with RetroDECK 0.10.0b due to the new layered Flatpak architecture. Users who rely on Ponzu should remain on an earlier version.
Core Changes
RetroDECK has been fully re-engineered with a modular, component-based infrastructure.
Each component: emulator, engine, client and system now runs in its own isolated sub-sandbox.
Upgraded runtime to org.kde.Platform 6.10.
Significantly reduced default application permissions with clearer, purpose-driven access rules.
New build and assembly pipeline reduces overall application size by approximately 800 MB.
New Components
New Emulators: XRoar (Tandy/Dragon), Azahar (Nintendo 3DS, new default), Ryubing (Nintendo Switch).
New Engine: OpenBOR with a custom RetroDECK launcher supporting .bor and .openbor formats.
New System: Flips (IPS/BPS ROM patching tool), available directly in the RetroDECK Configurator.
