Bit Slicer vs MemDBG

Bit Slicer is a free, open-source game trainer for macOS that searches for and changes values such as scores, lives and ammunition. Its scanner handles integers, floating-point values, strings, byte arrays and pointers, and can narrow search results. Users can inspect and edit live memory in a hex-editor-style window, dump memory to disk and alter memory-protection attributes. Debugging tools include instruction-access watches, live disassembly, breakpoints, backtraces, register manipulation and stepping, as well as byte or assembled-instruction changes. The app can inject assembly code into a running process, and scripts can automate virtual-memory and debugger methods. Saved Slice documents can be shared. The project says it can run as a normal user rather than root. Version 1.9.2 is listed as the latest release. The current release requires macOS 11.5 or newer, although the freeware plan lists macOS 10.8 or later. Support is directed to the wiki and Discord, and is not available 24/7.

MemDBG is a console payload and native frontend for memory inspection, scanning, debugging, trainer creation and research on PS4, PS5 and host machines. Its stated uses include offline homebrew development, reverse-engineering education, preservation and authorized security research. Scan workflows include exact values, process-wide searches, AOB patterns, pointer chains, unknown values and heuristic Smart Auto-Search. Debugging tools cover thread control, stepping, registers, breakpoints, watchpoints, stack walking and disassembly. Trainer workflows support .cht save and load, batchcode import, ON/OFF values, lock intervals and patch-to-trainer export. The frontend supports desktop-side Lua and Python plugins from repository manifests, with a public MemDBG plugin repository as its default source. It documents a GDB remote bridge for IDA Pro and an optional x64dbg plugin bridge. MemDBG is free and licensed GPL-3.0-or-later; it is in active pre-release development. Host builds bind to loopback by default, and the project recommends an allowlisted frontend IP for LAN sessions. Some macOS debugger actions may need SIP or code-signing changes; the iOS/iPadOS release artifact is unsigned.
