Read-Only DMA Game Entity Monitor

I need a purely read-only DMA pipeline that can sit on a separate board, pull live memory from a running game, and expose the positions, states, and IDs of all in-game entities for monitoring (think an “extra-sensory perception” overlay, but with absolutely no writes back to the host RAM)...
