PC handhelds
The Steam Deck and the other PC handhelds are x86-64 PCs with a built-in screen and controls. GameFrame's Windows PE path (Ghidra, Unicorn x86-64, Wine) applies to them directly.

Steam Deck
Hardware
Valve's Steam Deck came out on 25 February 2022 in North America and Europe. The OLED model followed on 16 November 2023. Its custom AMD APU is codenamed Aerith (7 nm) on the LCD model. The OLED model uses Sephiroth (6 nm). The Zen 2 CPU has 4 cores and 8 threads at 2.4 to 3.5 GHz. The RDNA 2 GPU has 8 CUs at 1.0 to 1.6 GHz. It has 16 GB of LPDDR5 on the LCD model and LPDDR5X on the OLED model. The 1280 by 800 screen is a 7-inch LCD at 60 Hz or a 7.4-inch OLED at 90 Hz (Wikipedia: Steam Deck).
SteamOS 3 is built on Arch Linux with an immutable file system and a KDE Plasma desktop. Windows games run through the Proton compatibility layer (Wikipedia: Steam Deck). Proton is Wine-based (not confirmed).
Tools
Use GameFrame's Windows PE path: Ghidra, Unicorn x86-64 and Wine (Home computers and the PC).
For an exact reimplementation
The LCD model's panel runs at 60 Hz. The OLED model's runs at 90 Hz. Record which panel a test ran on.
Other PC handhelds
Hardware
Other PC handhelds include the Asus ROG Ally and Lenovo Legion Go (2023) and the MSI Claw A1M (2024). The ROG Xbox Ally was announced in June 2025 and runs Windows (Wikipedia: Steam Deck).
Tools
These run PC games, so the Windows PE path applies as for the Steam Deck.
