DOSBox Cheat Engine vs memwatch

DOSBox Cheat Engine is a single-page web application for scanning, editing, and freezing emulated memory in DOSBox Staging. Search for values, narrow the results, and add memory addresses to a Cheat Table; values in the table can be changed by double-clicking or frozen so they do not decrease. Live memory polling can be paused during CPU-heavy game segments. Cheat tables can be exported and loaded as JSON files, and Shift-click or Ctrl-click supports range selection. The application connects to DOSBox Staging through its Web Server API, which must be enabled in the emulator configuration. It requires DOSBox Staging 0.83 or newer; the API web server's default local address is http://127.0.0.1:8086. Precompiled executables are offered for Windows and Linux, and the Python source can be run directly using only the standard library, without a pip installation. The project is MIT licensed and free. Closing the browser tab sends a signal for the Python server to shut down gracefully.

memwatch is a free, open-source macOS utility for searching and changing values in a running process’s memory through an interactive interface. Searches can target strings, floating-point numbers in 32- or 64-bit formats, and signed or unsigned integers from 8 to 64 bits. Comparisons such as equal, greater than, or less than can narrow results. Once values are found, memwatch can read, write, monitor, freeze, or unfreeze them. Its interface also has commands to pause and resume a target process and send it Unix signals, though execution-state support is described as experimental. The project presents memwatch as a macOS memory editor and says it should build and run on recent OS X versions. Its author describes using it for game cheats and as a debugging aid alongside tools such as gdb. Installation requires building from source with phosg and libamd64, then running make and sudo make install. Attaching to a target process uses sudo. The MIT License permits use without charge and supplies the software without warranty.
