Target Hardware Matrix — Linux, ARM64 and Handhelds

Every port on Good Old Games Dev — Jagged Alliance 2, Warlords III: Darklords Rising, Anno 1503 A.D. — Royal Edition, and Arcanum — is engineered against a shared cross-platform C++ & SDL2 hardware baseline:

Platform TierTarget DevicesCPU & OS — Graphics & Audio Stack

Handheld Input and Ergonomics Layer

Classic late-1990s strategy games and CRPGs were designed for high-precision desktop mice and full 104-key keyboards. To make them feel native on handhelds (MSI Claw, Steam Deck) and couch consoles (Khadas VIM1S), all four ports share a unified SDL2 GameController input layer:

  1. Dual-Curve Analog Cursor: Left or right stick drives the tactical cursor with sub-pixel precision at low deflection and fast map panning at full deflection, plus Left Trigger (L2) precision slow-down.
  2. Tactical & Radial Shortcuts: D-pad and shoulder buttons (L1/R1) cycle squad members, stances (Stand / Crouch / Prone in JA2), zoom levels (Anno 1503), and quick-save/quick-load slots.
  3. Integer & Aspect-Aware Scaling: Classic 640×480, 800×600, and 1024×768 pixel art is scaled cleanly to 1920×1080 and 1280×800 displays without shimmer or aspect distortion.
