MemoryEditor v0.5.0 — Memory Workbench

The big one: a Memory Workbench that brings a Cheat-Engine-style workflow to the Steam Deck.

🧰 Memory Workbench (new)

Attach to a game, then press Open Memory Workbench in the Quick Access panel for a full-screen page with:

• Address list — add addresses by absolute value (0x…) or by module + offset, give each a label and a type, and watch its live value. Per row: set a new value, freeze/unfreeze, view in the hex viewer, or remove.
• Memory viewer — a hex + ASCII dump of any address.
• Cheat tables — Save / Reload / Delete a table of addresses per game, keyed by its Steam App ID, so your list is there next time.
• Static tagging — addresses inside a loaded module are labelled with the module name.
• Add to Workbench — send any search result straight into the saved table.

Everything from before

Async scans with progress + cancel · live value refresh · value freezing + frozen panel · undo · hex/negative numpad entry · range + string search · auto-detect the running game.

Install (Desktop Mode)

Download memoryeditor-0.5.0.zip below, copy it to the Deck, then:

sudo rm -rf ~/homebrew/plugins/memory-deck ~/homebrew/plugins/memoryeditor
sudo unzip memoryeditor-0.5.0.zip -d ~/homebrew/plugins/
sudo systemctl restart plugin_loader

Requires Decky Loader. Personal project — not on any plugin store; install the attached zip manually.

Notes

• Found addresses aren't guaranteed to be the same after a game restart (ASLR). Saved tables keep your labels and types; re-find the address in a new session, or use module + offset for addresses inside a module. (Pointer scanning, which makes cheats survive restarts, is the next planned step.)
• This plugin reads and writes another process's memory. It can crash games. Use at your own risk.

MemoryEditor v0.4.1

A revived and modernised fork of Memory Deck — a scanmem-based memory scanner/editor for the Steam Deck, as a Decky Loader plugin.

What's in this release

• Modern Decky toolchain (@decky/ui + @decky/api, api_version 1)
• Async scans that no longer freeze the backend, with a live progress bar and a Cancel button
• Live value refresh in the results list (values tick in real time)
• Value freezing, with a dedicated Frozen Values panel
• Undo last change
• Hex / range / string search, plus negative and hex entry on the numpad
• Auto-detect the running game (🎮 one-tap attach)
• Correctness pass: fixed float search, the match-array walk, and set N= indexing
• Review cleanups: basename-based process filter, hex on signed types, quieter logging

Install (Desktop Mode)

Warning
