CoSMOS vs scanmem

CoSMOS is a free self-service gamehacking tool for people who want to modify their own games while waiting for trainers. It is offered in Steam Deck, PC Beginner, and PC Advanced versions, with options for beginners and experienced gamehackers. The Steam Deck edition is a native application for Linux and Steam Deck, with a simplified memory scanner and built-in disassembler. PC Beginner is integrated with Cheat Happens Aurora. PC Advanced includes a memory scanner, VEH debugger, script engine, disassembler, dump viewer, speedhack, .NET assembly explorer, reference search, process viewers, and script editor; its listed version is 6.1.5. CoSMOS uses hardware-accelerated scans and can read and import 99% of CheatEngine tables. The free tool requires no registration, has no locked features, and includes no adware or hidden software. Cheat Happens provides technical support through its message board. The maker advises using cheats and trainers offline only and says it does not make cheats for online or multiplayer games.

scanmem is a free, open-source interactive debugging utility for finding and changing variable values in an executing process. It searches a process by PID and uses values observed over successive scans to narrow the possible memory addresses. The command-line tool can search for exact values, compare changed or unchanged values, find increases or decreases, take snapshots, and search strings when configured for string scans. It can monitor matches as their values change and set values for selected matches or all known matches. GameConqueror provides a graphical front end with a process finder, flexible search syntax, variable locking, and a memory browser and editor; users can choose search regions and types. The project separates the command-line frontend from libscanmem, which performs the scanning. The project describes scanmem as a Linux utility and documents an Android build using a standalone Android NDK toolchain. Linux interactive commands require libreadline and a mounted /proc filesystem, while the GUI has additional dependencies. The default scan data type is int, though the option command can change it. scanmem is GPLv3; libscanmem is LGPLv3.
