Bit Slicer vs ProMod

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.

ProMod manages memory modifications for individual processes on macOS and iOS. On a Mac, it writes four-byte ARM instructions into a target process and automatically uses code caving for larger patches. Special mods can follow an address in a CPU register and monitor or rewrite float or int32 values when thresholds are met. One-instruction mods can use hardware breakpoints without writing to the target app’s memory; the FAQ says a Mac processor allows six at a time. Keyboard shortcuts can trigger one or several mods, with audible cues. Setups can be saved and shared as portable .pro files, with built-in or password encryption. Bytes Diff scans for memory changes, and Memory Locator searches for hex patterns. Users can enter raw hex or ARM64 assembly, which ProMod assembles, and disassemble surrounding instructions. The Mac app requires an Apple Silicon Mac with macOS 12.0 or later; Intel Macs are unsupported. ProMod Mobile runs on non-jailbroken iOS devices but requires injecting libProModMobile.dylib with Sideloadly or a similar tool. The maker describes it for debugging, learning, single-player, and offline use.
