CoSMOS vs MemDBG

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.

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.
